New York Mets pitching prospect Jack Wenninger could still be the next pitcher in line for a promotion when the team needs to fill a rotation spot despite turning in his worst outing of the season in his latest start. The Mets' fifth-ranked prospect carried a sterling 1.51 ERA into Sunday's start for Triple-A Syracuse, but yielded six runs (four earned) on five hits and two walks while striking out five in 5 1/3 innings pitched. Surprisingly, two of the hits were home runs after the right-hander had allowed just one home run all season in his first eight starts (35 2/3 IP). Still, the 6-foot-4 hurler owns a 2.20 ERA (4.38 FIP), is limiting opponents to a .178 average, and has recorded 44 strikeouts in 41 innings of work, which should be enough to give the organization confidence to call on him when needed. Jonah Tong appears to be getting the nod to fill Clay Holmes' spot in the rotation for now, but if he or Christian Scott falter or someone hits the injured list, Wenninger could be on the way to Queens. For managers looking for pitching help, the former sixth-round draft pick is a worthwhile stash for his ability to limit damage and record a strikeout per inning.

Pittsburgh Pirates outfielder Jhostynxon Garcia was promoted to the majors last week, and he's an encouraging waiver wire target given his potential to launch home runs. Garcia has yet to homer through 27 MLB at-bats (between 2025 with the Red Sox and 2026 with the Pirates), but he launched 21 homers across 114 minor league games last year, and he had slugged another six this year. Strikeouts are a major concern for the 23-year-old, who owns a 28.6% K% in the majors in 2026. However, as he starts to get more comfortable against MLB pitching, his strikeout rate should go down and his home run rate should go up. There's above-average power potential here, so managers should consider making him a priority addition on the waiver wire. At the moment, he's still available in 98% of fantasy baseball leagues.

Colorado Rockies outfield prospect Cole Carrigg has been a consistent producer all season at Triple-A Albuquerque, reaching base via hit or walk in 43 of his 47 games played. The Rockies' sixth-ranked prospect's season slash line stands at a robust .358/.424/.551 with five home runs, while his speed has helped him to five triples (second-most in the minors) and 26 steals. That kind of multi-category production should interest fantasy managers, and with just a 14.2 percent strikeout rate, the switch-hitter clearly doesn't appear to be overmatched at that level. A promotion to the big league club could happen in the coming weeks, and with solid contact, power, and above-average speed, the 24-year-old has quickly become a top hitter to stash in most leagues.

New York Yankees designated hitter Giancarlo Stanton (right calf) is currently on the 10-day injured list with a right calf strain, but he's getting ready to return to the active roster within the next week or two. Stanton is a talented power hitter when healthy, and he's worth stashing in fantasy baseball leagues ahead of his impending return. Prior to the injury this year, Stanton was slashing .256/.302/.422 with three home runs, 14 RBI, a 6.3% walk rate, a 30.2% strikeout rate, and 105 wRC+. The power output was down a little, but that could just be attributed to a small sample size. Since landing on the IL, Stanton's roster share across fantasy baseball has fallen to just 27%. He's available in 73% of leagues, making him an intriguing stash in hopes that he can offer a boost to your lineup from June through September.

Philadelphia Phillies third baseman Alec Bohm's counting statistics have been underwhelming this year, but his underlying metrics provide reason for optimism. So far, he's slashing .210/.274/.331 with very little power (five home runs) and even less speed (zero steals). He has a wRC+ of 70, which is the worst of his career and his first sub-100 mark since 2022. Bohm has a paltry 3.2% barrel rate, but we're encouraged by his 90.1 mph average exit velocity (64th percentile) and his 36.4% squared-up rate (97th percentile). The quality of contact has been decent, and that could lead to more home runs (or, at the very least, more extra-base hits) going forward. He's also not a major strikeout liability, as his strikeout rate, chase rate, and whiff rate are all 84th percentile or better. We're not saying Bohm is a lock to turn things around, but now that he's rostered in just 31% of leagues, he's a worthwhile stash in deeper formats based on some encouraging underlying data.

New York Mets starting pitcher Christian Scott tossed 5.2 innings of scoreless baseball during his latest start against the Miami Marlins on Sunday. Along the way, he allowed four hits and two walks while striking out five batters. Scott is 0-3 through 15 career starts, but it's not for a lack of quality outings. He owns a 4.09 career ERA, including a 3.20 ERA and a 3.47 FIP this season. Across six starts (25.1 innings) in 2026, he has also amassed 10.66 K/9, 4.97 BB/9, 0.36 HR/9, and a 28.6% ground ball rate. Given how well he has pitched this year, Scott has emerged as a priority target on the waiver wire in fantasy baseball. He ranks #81 among starters in RotoBaller's latest fantasy baseball rankings, and he is available in more than 90% of leagues.

Milwaukee Brewers infield/outfield prospect Jett Williams has hit safely in nine of his last 12 games, going 13-for-45 (.289) over that stretch with three doubles, two triples, and two home runs, upping his season-long slash line to .247/.411/.578. The Brewers' third-ranked prospect also has 11 steals for Triple-A Nashville and is boasting a 14.0 percent walk rate (21.6 percent strikeout rate) through 49 games. The former first-round draft pick could be nearing an MLB debut, and with his skillset, along with positional versatility (eligible at 2B, SS, OF on Yahoo!), the 22-year-old should be considered a top hitter to stash for his multi-category contribution potential.

Colorado Rockies corner infield/outfield prospect Charlie Condon's major league debut could be right around the corner as the former third-overall draft pick is in the midst of a seven-game hit streak, during which time he's gone 9-for-28 (.321), including four doubles and a home run. Not only that, but Rockies first baseman TJ Rumfield exited Monday's contest after being hit by a pitch on the hand. X-rays were negative, but if it is determined that he'll need to miss some time, then Condon could very well be his replacement. After the recent seven-game hit streak, Condon is slashing .247/.374/.404 with five home runs and four steals, and although his strikeout rate remains elevated at 25.6 percent, a 14.2 percent walk rate shows that the Rockies' second-ranked prospect has a keen eye. With a potential debut on deck while calling Coors Field home, the 6-foot-5 power hitter should be considered a top offensive stash in most leagues for his home run upside.

Kansas City Royals veteran right-handed reliever Carlos Estevez's (foot, shoulder) velocity was noticeably down in spring training, and then he allowed six earned runs on four hits in just one-third of an inning before being placed on the 15-day injured list with a foot injury. While rehabbing in the minors and working on his mechanics, Estevez suffered a rotator-cuff strain in his right shoulder, pushing his return back even further. Despite his rough 2026 season so far, though, he is rostered in exactly half of Yahoo leagues because of the potential for him to be reinstated as KC's primary closer when he returns to full health. It's unclear when Estevez might come off the IL, but current closer Lucas Erceg blew his fourth save of the season and was hit with his second loss in the 4-3 loss to the New York Yankees on Monday. Fantasy managers desperate for saves with room on their IL should consider stashing Estevez, who had a league-leading 42 saves in his first year with the Royals in 2025.

Milwaukee Brewers left-handed reliever Aaron Ashby has zero saves and zero holds in 33 innings pitched so far in 2026 in 24 appearances (one start), but he's rostered in 38% of Yahoo leagues. He's made up for that with a league-high eight wins, a 2.18 ERA (2.25 FIP), and a 1.30 WHIP with a career-best 33.6% strikeout rate in 33 innings pitched for the Brew Crew. The 28-year-old southpaw originally came up in the Brewers' system as a starting pitcher, but frequent injuries have turned him into a full-time reliever. The role has suited him well because of his high-end velocity and swing-and-miss secondary offerings. Fantasy managers cannot rely on Ashby to continue vulturing wins, though, and he's also sporting a career-high 12.1% walk rate. However, his strikeout upside in a high-leverage, multi-inning role makes him attractive in deeper leagues. He was also quite good in 2025, sporting a 2.16 ERA, 1.17 WHIP, a career-high three saves, and a 76:24 K:BB in 66 2/3 innings.

Minnesota Twins right-hander Mick Abel (elbow, triceps) was placed on the 15-day injured list on April 20 with right-elbow inflammation, and he had a setback in early May, when he complained of soreness in his right triceps after throwing a bullpen session. The 24-year-old is being built back up slowly, but the good news is he has been feeling better since receiving a cortisone injection in his triceps muscle. Since Abel has yet to face hitters, he probably won't be able to rejoin Minnesota's starting rotation until at least mid-June or later. Still, fantasy managers in deeper leagues in need of starting pitching depth should consider stashing the former first-round pick by the Philadelphia Phillies back in 2020. In his first four appearances (three starts) for the Twins in 2026, Abel posted a 3.98 ERA (2.73 FIP) and 1.57 WHIP with 23 strikeouts and 10 walks across 20 1/3 innings pitched. Abel has above-average velocity and plenty of strikeout upside, but control remains an issue. If he can throw more strikes, Abel could be a breakout candidate in 2026 once he gets healthy. He's rostered in only 13% of Yahoo leagues.

Cincinnati Reds second baseman Matt McLain went 13-for-41 (.317) with three home runs, three doubles, 10 RBI, seven runs scored, and two stolen bases in 12 games from May 6 to May 18. In four games since then, though, he has gone hitless in 19 plate appearances with an RBI, no walks, and seven strikeouts. In 21 games in May, McLain is batting .178 (13-for-73) with three homers, three doubles, 11 RBI, seven runs, two steals, six walks, and 17 strikeouts across 80 plate appearances. On the season, the 26-year-old former 17th overall pick in 2021 out of UCLA is hitting under .200 with a .296 on-base percentage, .326 slugging percentage, and .622 OPS in 187 at-bats in his third season in the big leagues. McLain had an impressive 31 home runs, 100 RBI, and 32 steals in 236 games in his first two seasons in the majors (he missed 2024 due to injury), making him a nice sleeper candidate in fantasy going into this year. He has stayed healthy so far, but the results have been disappointing. If McLain continues to struggle, he could start to lose playing time as we get into the summer months.

Atlanta Braves starting pitcher Spencer Schwellenbach (elbow) has yet to pitch in 2026 after undergoing surgery to remove bone spurs in his right elbow in February. However, the 25-year-old is reportedly on the verge of beginning a throwing program and could be progressing towards a mid-summer return to the big leagues. Schwellenbach showcased high-end upside in 2025, recording a 7-4 record with a 3.09 ERA, 0.97 WHIP, and 108 strikeouts across 110 2/3 innings (17 starts) before fracturing his right elbow in late June. Given his track record of elbow issues, Schwellenbach's profile carries a fair amount of injury risk for fantasy managers. Still, he's provided must-start production when healthy since making his MLB debut in May 2024. For any fantasy manager with an open roster spot, Schwellenbach could be worth targeting on the waiver wire as a stash candidate.

As the early portion of the 2026 MLB season gives way to the summer months, Cleveland Guardians outfielder Angel Martinez looks like he could be on the verge of a breakout campaign. Across his first 186 plate appearances of the year, the 24-year-old is hitting .246/.286/.468 with nine home runs, 27 RBI, 24 runs scored, and eight stolen bases. Martinez has added significant power while also reducing his swing-and-miss, raising his barrel rate from 3.5% to 8.5% and cutting his strikeout rate from 22.7% to 18.8%. He's also been significantly more aggressive as a runner, as his current stolen base total (eight) already matches what he posted across 139 games in 2025. While Martinez may not provide elite production in any one fantasy category, he profiles as a balanced contributor who should provide quality counting stats due to his everyday role in the Cleveland outfield. He should hold broad waiver wire appeal for fantasy managers across most formats.

Toronto Blue Jays right-hander Max Scherzer (forearm) will throw a live batting practice session in Toronto on Wednesday, manager John Schneider told Ben Nicholson-Smith of Sportsnet. In addition to right-forearm tendinitis, Scherzer is battling left-ankle inflammation and a thumb issue. The 41-year-old future Hall of Famer is breaking down near the end of his career, but as per usual, he's not going down without a fight. The three-time Cy Young winner and eight-time All-Star is building himself back up to try to return to Toronto's starting rotation, although it's been a long process. Scherzer has been on the 15-day injured list since late April and will most likely need a lengthy minor-league rehab assignment, so in a best-case scenario, he might not rejoin the Jays' starting rotation until mid-June or later. He struggled in his first five starts before landing on the shelf, going 1-3 with a 9.64 ERA (8.32 FIP) and 1.61 WHIP with 10 strikeouts and eight walks in 18 2/3 frames. Scherzer is only rostered in 4% of Yahoo leagues and should be ignored in mixed formats all year.

Houston Astros closer Josh Hader (biceps) has yet to pitch in the big leagues in 2026 as he recovers from left biceps tendinitis. However, the 32-year-old has already made seven minor league rehab appearances and is reportedly targeting a return to the Houston bullpen in the first week of June. Hader was one of the game's elite relievers in 2025, pitching to a 2.05 ERA and 0.85 WHIP with 76 strikeouts and 28 saves across 52 2/3 innings (48 games). He's looked like his vintage self in his rehab outings as well, racking up 11 strikeouts while allowing just six baserunners across seven innings of work. Hader profiles as a high-end fantasy closer once healthy and should be stashed off the waiver wire in all league formats.

Across 129 plate appearances so far in 2026, Athletics infielder/outfielder Zack Gelof is hitting .229/.283/.424 with six home runs, 17 RBI, 21 runs scored, and six stolen bases. The 26-year-old opened the season with Triple-A Las Vegas, but he's worked his way into an everyday role as the A's third baseman since being recalled in mid-April. While Gelof's 25.6% strikeout rate in 2026 is a significant improvement from the 34.4% rate he posted across 547 plate appearances in 2024, he still profiles as a negative contributor in the batting average category for fantasy managers. However, Gelof owns a 9.8% career barrel rate at the big-league level and has swiped 46 bases across 275 total MLB games. As long as he limits his whiffs enough to stay in the everyday lineup, Gelof carries 20-homer, 20-steal upside.

According to Jeff Passan of ESPN, the Athletics are promoting top left-handed pitching prospect Gage Jump to the major leagues. Currently, the southpaw is ranked as the overall No. 41 prospect in the entire sport on MLB.com. Jump was selected with the 73rd overall pick in the 2024 MLB Draft out of LSU and was enjoying a dominant stretch at Triple-A Las Vegas prior to his promotion. Over his last two outings (11 frames), Jump did not allow a run while racking up 15 punchouts to just one free pass. Over his first 27 innings of the season, the southpaw posted a much higher 6.67 ERA but continued flashing elite strikeout potential, totaling 41 over this stretch. While Jump does not have much experience against the top hitting of the minor leagues, he has shown he can tally strikeouts at a dominant rate. Managers should expect Jump to slot into the starting rotation when he joins the roster, which makes him a solid pick-up in all 12+ team leagues ahead of his debut.

New York Mets rookie outfielder Carson Benge got off to a rough start to his MLB career in the early portion of 2026, hitting .189 with a .525 OPS across 97 plate appearances through the end of April. However, the 23-year-old has turned the corner in May, hitting .307/.378/.398 with one home run, 12 RBI, 16 runs scored, and three stolen bases across 98 plate appearances so far this month. Benge's 8.0% barrel rate for the season likely limits his power upside. Still, he should provide fantasy managers with 15-plus homer power over the course of a full season while bringing surplus value in the speed and batting average categories. Benge has also batted in the leadoff spot in the Mets' lineup in each of his last 14 games played, helping him rack up counting stats. In leagues where he's not already rostered, Benge profiles as a steady cross-category contributor with upside to target on the waiver wire.

Cincinnati Reds right-hander Hunter Greene (elbow) has not yet pitched in 2026 after undergoing elbow surgery in mid-March. However, the 26-year-old is slated to throw a bullpen on Tuesday and could be nearing the start of a minor league rehab assignment. Greene was one of the best pitchers in baseball in 2025, recording a 7-4 record with a 2.76 ERA, 0.94 WHIP, and 132 strikeouts across 107 2/3 innings (19 starts). He averages 99.4 miles per hour on his fastball and recorded an elite 25.2% K-BB rate. Greene is currently on the 60-day injured list and will likely require at least a few starts in the minors before he makes his return to the big-league mound. Still, fantasy managers should be looking to stash Greene off the waiver wire due to his league-winning upside once he returns to full health.
