Toronto Blue Jays outfielder Addison Barger (elbow) is currently on the injured list with right elbow inflammation, but he could be an intriguing waiver wire target once he's activated back to the 26-man roster. Barger has played in just nine games this season and is off to a putrid start, going 1-for-22 with zero home runs, two RBI, five walks, and seven strikeouts. The poor results at the plate were likely caused by his injury issues; he missed a month earlier this season with an ankle injury, and now, he has a right elbow problem. Assuming this second IL stint allows him to shake off the injury bug and return at 100%, there's a strong chance that he'll produce better results at the plate. Theoretically, he could get back to his 2025 form, which included a .243/.301/.454 slash line with 21 home runs and 107 wRC+. Managers should consider stashing Barger now, so that they can reap the potential rewards when he returns. Then, even if he does continue to struggle after clearing the injury hurdle, managers can drop him -- no harm, no foul. There's minimal risk and plenty of upside in adding Barger off the waiver wire while he's still injured.

Los Angeles Angels starting pitcher Reid Detmers allowed eight runs on Tuesday, but he's still a potential waiver wire addition given his consistent ability to generate strikeouts. Detmers' ERA jumped to 5.07 in the loss, but his 3.25 xERA and 3.10 FIP both suggest that he could be due for some favorable regression going forward. We already know he's capable of racking up strikeouts, as he posted 11.31 K/9 last year and is sitting at 9.98 K/9 across 10 starts so far in 2026. He limits walks and home runs, too. Detmers' ugly 1-5 record is a reflection of the Angels' struggles this year, and fantasy managers should feel comfortable adding him off the waiver wire based on his expected metrics and strikeout rate. He's available in 71% of leagues, and he ranks as the #72 starting pitcher in RotoBaller's latest fantasy baseball rankings.

Detroit Tigers starting pitcher Troy Melton (elbow) made his fourth rehab appearance on Wednesday, allowing one run, two hits, zero walks, and six strikeouts across five innings of work with the organization's Class-A affiliate. Melton has been on the 60-day injured list since March, and he has not yet pitched in an MLB game this season. He's eligible to be activated from the IL as early as Sunday, but the Tigers are also allowed to keep him on rehab assignment through the rest of the month, if they desire. It does seem like he's very close to returning, as Melton has tossed 11.2 innings across four rehab starts with just two earned runs and 16 strikeouts. Given how well he has pitched in the minors, he represents an intriguing waiver wire addition in fantasy baseball. Managers would be wise to stash him ahead of his return to the Tigers' 26-man roster. He's currently rostered in just 2% of leagues, but that percentage will increase once the Tigers officially activate him. Managers should be optimistic about his potential to build on his rookie season last year, when he posted a 2.76 ERA between the rotation and bullpen.

San Diego Padres starting pitcher Randy Vasquez has been highly effective in 2026, generating waiver wire interest across most fantasy baseball leagues. Through nine starts this year, Vasquez is 5-1 with a 2.68 ERA, 3.31 FIP, 8.05 K/9, and 2.32 BB/9. He was highly effective with zero runs and zero walks over six innings in his latest outing against the Mariners on Friday, and he'll have a chance to build off that success in his projected start against the Los Angeles Dodgers this Wednesday. Managers in need of a starting pitcher -- whether it's for today only, or rest-of-season -- should strongly consider Vasquez. While his strikeout numbers aren't otherworldly, he has effectively limited walks and runs while pitching deep into games. As it stands, he is available in 45% of leagues and ranks #69 among starters in RotoBaller's latest fantasy baseball rankings.

Miami Marlins outfielder Esteury Ruiz isn't the flashiest name in fantasy baseball as he hovers near the Mendoza line, but his ability to steal bases still makes him an intriguing waiver wire addition. He is slashing .200/.219/.467 with two homers, a 3% walk rate, and a 28% strikeout rate across 19 games (32 plate appearances). Interestingly, he has reached base seven times and has stolen seven bases, reminding fans and managers just how successful he can be on the basepaths. He's also tapped into a little more power (albeit over a small sample size), keeping his wRC+ at a mark of 79. Playing time has been hard to come by for Ruiz, largely due to the fact that he isn't getting on base a lot. However, his power and speed combo still makes him an intriguing waiver wire addition, especially if he gets in the lineup more often. He's widely available in most leagues, with a current roster share of just 1%.

Colorado Rockies outfield prospect Cole Carrigg is now firmly on the stash radar in Week 8 of the fantasy baseball season. Carrigg opened the 2026 season by making his Triple-A debut and has shown minimal growing pains when facing the top pitching of the minor leagues. Over his first 42 games at the top club of the Colorado system, Carrigg has posted a dominant .355/.415/.538 slash line with nine doubles, five triples, four home runs, and an eye-catching 26 stolen bases. During this stint, he has also shown a strong eye at the dish, striking out just 25 times and drawing 16 walks. In 2025, the San Diego State product spent his entire season at Double-A but posted a much lower .237 AVG. Given that Brenton Doyle and several corner outfielders on the MLB roster have not put together strong starts, Carrigg could be in the mix for a debut in the immediate future. His high-end speed makes him a top option to stash in all 12-team leagues.

Minnesota Twins shortstop Brooks Lee has emerged as a potential waiver wire addition in fantasy baseball as managers look for midseason upgrades. One of Lee's biggest strengths is his role; he has played at shortstop nearly every day for the Twins, logging 46 games and 178 plate appearances so far in 2026. He's also having a fair season at the plate, slashing .248/.299/.388 with five home runs, three steals, a 6% walk rate, an 18% strikeout rate, and 92 wRC+. While he's hitting a bit below average, that slash line, walk rate, and wRC+ also represent the best marks of his young career. Because he has flashed modest power and slightly improved on-base skills, Lee has waiver wire appeal in deeper fantasy leagues. With a roster share of 26%, Lee, who is eligible at third, second, and shortstop, remains available for infielder-needy managers in most leagues.

New York Yankees right-handed pitching prospect Carlos Lagrange has continued to improve in the minor leagues and is seeing his stash value continue to climb each week. Even though Carlos Rodon is back in action and Gerrit Cole is set to return later this week, fantasy managers should monitor Lagrange at Triple-A, as he could be called up during the second half. Lagrange is currently viewed as the team's No. 4-ranked prospect on MLB.com and the overall No. 76 prospect in the game. Last summer, the flamethrower split his time at High-A and Double-A, which earned him the ticket to Triple-A to open the 2026 campaign. During his first taste of Triple-A, Lagrange has continued to flash impressive strikeout upside, totaling 52 over 38 1/3 innings. However, he has endured some growing pains, holding a 4.23 ERA and a 1.33 WHIP. While he needs to improve his command to be in serious contention for a promotion, another injury to the Yankee pitching staff could pave the way for an early debut. For now, he remains a sneaky stash target for those in deeper leagues with multiple N/A spots.

Miami Marlins outfield prospect Kemp Alderman (wrist) was on pace to compete for an early MLB debut this season, but he suffered an injury earlier this week and was officially moved to the seven-day injured list. Alderman sustained a wrist injury during a collision at a Triple-A contest. While this does hurt his short-term value, managers in deeper formats should continue to monitor his status, as he may not need another lengthy stint in the minors once he is cleared to play. While Alderman has primarily been an outfielder in the minor leagues, they have begun moving him to first base, which is a position of weakness on the MLB roster. Through 40 games with the Jumbo Shrimp this season, Alderman has launched nine home runs while holding a .303/.376/.526 line. While the injury has hurt his short-term stash value, he remains a must-watch name as he could continue to have a clear path to the big leagues once activated.

Milwaukee Brewers infield prospect Jett Williams is quickly knocking on the MLB door as he has swung a hot bat in May at Triple-A Nashville. Since May 1, the infielder has carried a stellar .308/.464/.577 slash line with four doubles, two triples, two home runs, three stolen bases, and a 13:14 K:BB. This is worth noting, as Williams struggled in April, posting a much lower .227/.324/.361 slash line with a modest .685 OPS. The Brewers acquired Williams in the winter as part of the move that sent their former ace, Freddy Peralta, to the New York Mets. Last summer, Williams spent most of his time with Double-A before joining Triple-A Syracuse in the second half. While the Brewers may keep Williams at Triple-A for a bit longer, he is showing he is more than capable of earning a taste of MLB pitching in the coming weeks.

Arizona Diamondbacks infield/outfield prospect Jordan Lawlar (wrist) has been on the 60-day injured list for the majority of the regular season but has recently begun to make strides in his return. Earlier this week, the former top prospect took dry swings for the first time. Additionally, the team's manager, Torey Lovullo, noted that his wrist fracture continues to heal quite well. While Lawlar is still several weeks away from returning to game action, it appears he is progressing well through the early stages of his recovery. Before the injury, Lawlar appeared to have emerged as a primary option in the outfield, appearing in six games and posting a .333 AVG with one double and one home run. During spring training, he flashed high-end upside, holding a .333/.448/.604 line over a 17-game stint. Given that his potential return date may not be for another month, managers should only consider stashing him in deeper 15+ team leagues for the time being.

San Francisco Giants outfielder Jung Hoo Lee (back) remains out of the team's starting lineup for Wednesday's series finale against the division-rival Arizona Diamondbacks, according to MLB.com. Drew Gilbert is making the start in center field and is batting ninth against D-backs right-hander Merrill Kelly. Lee is making progress since being removed from Monday's game in Arizona early with back spasms, but he will take a seat for the second straight game as a precaution. The Gigantes don't have a game on Thursday, so Lee may return to the starting nine for Friday's series opener against the Chicago White Sox. The 27-year-old Japanese native doesn't offer fantasy managers much in any one category, and he's currently slashing .268/.311/.385 with a .696 OPS, three home runs, 17 RBI, and 20 runs scored in 193 plate appearances across 48 games played in 2026. However, he's been better in May, going 13-for-46 (.283) with a homer and five RBI in 11 games. He's currently riding a modest five-game hitting streak.

Houston Astros right-hander Hunter Brown (shoulder) got up to 96 mph in a 22-pitch live batting practice session on Tuesday, manager Joe Espada told Chandler Rome of The Athletic. As long as Brown feels good on Wednesday, he will start a minor-league rehab assignment this weekend. Everything is progressing on schedule for Brown, who could be ready for activation from the 60-day injured list when he's eligible in mid-June. The 27-year-old former fifth-round selection by Houston in 2019 out of Wayne State has quickly developed into a fantasy baseball ace. He was a first-time All-Star in 2025, going 12-9 with a 2.43 ERA (3.14 FIP) and 1.02 WHIP with a career-high 206 strikeouts and 57 walks in 185 1/3 innings across 31 starts in his third full season in the majors. Brown allowed just one earned run with six walks and 17 K's in 10 2/3 innings in his first two starts in 2026 before injuring his shoulder. He's rostered in 95% of Yahoo leagues and should be stashed everywhere.

Colorado Rockies center fielder Brenton Doyle (oblique) is considered day-to-day with a left-oblique contusion that he suffered when diving for a ball in Tuesday night's game against the Texas Rangers, according to Manny Randhawa of MLB.com. Fantasy managers will want to check back shortly to see if Doyle is in the lineup for Wednesday's game against the visiting Rangers at Coors Field, but there's a good chance he'll be out of action. The Rockies begin a series in Arizona against the Diamondbacks on Thursday, and Doyle might also be unavailable for that contest. Although the good news is that Doyle's injury isn't a typical oblique strain that often requires an injured-list stint, he could still miss some time. The 28-year-old former fourth-rounder in 2019 out of Shepherd University had 23 home runs, 72 RBI, and 30 steals in a breakout 2024 campaign, but he failed to live up to expectations last year and continues to fall in 2026, hitting just .207 (23-for-111) with just one homer, four RBI, and nine steals in 43 games to this point. Doyle's tumble has cost him regular playing time in Denver.

Minnesota Twins right-hander Zebby Matthews took the loss on Tuesday against the visiting Houston Astros at Target Field, but he had another promising performance in his second start this year in the big leagues. The 25-year-old allowed two earned runs on five hits (one homer) while walking none and striking out six in six innings of work. In his two starts for the Twins, the former eighth-round selection out of Western Carolina in 2022 has a 1.38 ERA (2.65 FIP) and 0.77 WHIP with 11 strikeouts and only one walk in 13 innings pitched against the Astros and Miami Marlins. Matthews settled in nicely after allowing a two-run homer to Isaac Paredes in the first inning, and he threw 66 of his 100 pitches for strikes on the evening. He is scheduled for a two-start week next week, with his first matchup coming against the Chicago White Sox, so he should become more popular off the waiver wire going into Week 9 of the fantasy baseball season. Matthews is only rostered in 26% of Yahoo leagues and deserves a look for his solid control and strikeout upside.

Although San Francisco Giants right-handed reliever Caleb Kilian picked up a hold on Tuesday night, he was also hit with the loss in the 5-3 defeat at the hands of the division-rival Arizona Diamondbacks. Kilian struggled in a high-leverage spot, allowing three runs (two earned) on two hits while striking out one to pick up his second loss of the season. The 28-year-old earned his second save on May 12 in a scoreless appearance with a strikeout against the division-rival Los Angeles Dodgers, but he also allowed a solo home run in two-thirds of an inning against the Athletics on May 16. So Kilian has now allowed three earend runs in two innings in his last two appearances, and in May, he's surrendered seven runs (five earned) on seven hits (two homers) while walking five and striking out six in 7 1/3 frames with two losses, two saves, and a hold. Lefty Matt Gage blew the save against Arizona on Tuesday night, but Kilian is firmly on the hot seat in San Fran's closer-by-committee approach, with Keaton Winn and Erik Miller trending up for fantasy managers desperate for saves.

St. Louis Cardinals right-handed closer Riley O'Brien blew his fourth save of the season on Tuesday in an eventual 9-6 win over the Pittsburgh Pirates in 10 innings, allowing two runs on two hits while walking one and hitting two batters in an inning of work. The 31-year-old flamethrower could not protect a two-run lead in the ninth inning. Despite the rough appearance on Tuesday night, O'Brien is still 3-1 with a 3.13 ERA and 1.00 WHIP with 25 strikeouts across 23 innings. He is still tied for third in the league with 13 saves. O'Brien has blown two saves in May but has also picked up five saves while allowing six earned runs on nine hits in 7 2/3 innings of work. He has not been perfect and has given up multiple runs in four outings this year, but overall, O'Brien has mostly been solid for the Red Birds and shouldn't be in any immediate danger of losing save opportunities in St. Louis.

Minnesota Twins right-hander Taj Bradley (pectoral) is throwing a bullpen session on Wednesday, so he may return from the 15-day injured list to make a start on Saturday in Boston against the Red Sox if everything goes well with his bullpen session, according to Matthew Leach of MLB.com. Bradley threw 65 pitches in a minor-league rehab outing with Triple-A St. Paul on Sunday and could return to Minnesota's starting rotation this weekend. This is a reminder for fantasy managers to check their waiver wires to see if Bradley is available. If he is, he's certainly worth a pickup, especially with a potential matchup this weekend against the last-place Red Sox, who currently rank 27th in baseball with a .675 OPS. The 25-year-old Bradley was pitching very well before suffering from pectoral inflammation, going 4-1 with a 2.87 ERA (3.50 FIP) and 1.19 WHIP with 52 strikeouts and 17 walks in 47 innings across his eight starts. He's currently rostered in 75% of Yahoo leagues.

St. Louis Cardinals shortstop Masyn Winn (knee) is considered day-to-day after an MRI exam on his left knee came back negative, according to Amber Winkler of the St. Louis Post-Dispatch. Despite having an off day on Monday, Winn was not in the starting lineup for the series opener against the Pittsburgh Pirates on Tuesday after injuring his knee in the loss to the Kansas City Royals in Sunday's series finale. The good news with his MRI means that Winn could be back in action as early as Game 2 of the series against Pittsburgh on Wednesday. With Winn out on Tuesday, the Cards gave Cesar Prieto the start at the 6. The 24-year-old former second-round pick back in 2020 has slashed .255/.331/.353 with a .684 OPS, only one home run, 17 RBI, 18 runs scored, and four stolen bases in 175 plate appearances this season across 41 games played. Fantasy managers will want to check back a bit later to see if Winn is back in St. Louis' starting lineup against Pirates right-hander Carmen Mlodzinski.

Toronto Blue Jays starting pitcher Shane Bieber (elbow) has yet to pitch in 2026 as he deals with lingering inflammation in his surgically repaired right elbow. However, the veteran right-hander has progressed to facing live hitters and could be nearing a rehab assignment. Bieber has barely pitched over the last two seasons after undergoing Tommy John surgery in April 2024. Still, he was effective in a small sample size of 40 1/3 innings (seven starts) for Toronto in 2025, posting a 4-2 record with a 3.57 ERA, 1.02 WHIP, and 37 strikeouts. While fantasy managers must take Bieber's considerable injury risk into account at this point in his career, the 30-year-old should still be capable of providing quality production when healthy. Managers with an open roster spot may want to consider stashing Bieber off the waiver wire ahead of his potential return, which appears as though it could come in mid-to-late June.
