Arizona Diamondbacks outfielder Ryan Waldschmidt has impressed through his first 10 games in the majors and looks ready to be a long-time fixture in Arizona's outfield moving forward. The 23-year-old is the team's No. 1 prospect according to MLB Pipeline and has lived up to the hype, hitting .313 (6-for-32) with four doubles, three stolen bases, three walks, and six RBI. He hasn't hit a homer yet in the majors, but had 18 in 134 games in the minors in 2025 and three in 34 games in Triple-A before his promotion. He has a 16.7% barrel rate and has caught barrels in back-to-back games after going 3-for-3 with two doubles in Monday's 12-2 rout of the Giants. Waldschmidt is a great fantasy baseball addition if you need outfield depth at this point in the season and offers well-balanced production with good speed and batting average production right away.

Washington Nationals third baseman Brady House was optioned to Triple-A on Monday, in the corresponding move that brought outfielder Dylan Crews back to the MLB roster. House has seven homers in his 44 games with a .227 batting average and .302 wOBA. House had a 43% hard-hit rate and 10.5% barrel rate, and his BABIP of .280 was below league-average. Some of his lower numbers were tough luck, but he also did have a 28.2% strikeout rate. He's always been a high-strikeout, high-homer prospect, but his defense has dropped off significantly this season. He seemed to be trending up lately, but the team may want him to get more full-time work in Triple-A while they fill in with Jorbit Vivas and Jose Tena in the majors. At this point, House is droppable in almost all formats, although he does have power upside if he gets another call later in the season.

Seattle Mariners shortstop/third baseman Colt Emerson only needed two career games to make an impact as he hit his first MLB homer on Monday night in his team's 6-1 win over the White Sox. Emerson went 1-for-4 with the eighth-inning three-run blast. He started each of the last two games at the hot corner for the Mariners, who are set to give him a long look at that spot with Brendan Donovan (groin) on the injured list. Emerson is just 20 years old but hit .255 with seven homers and 10 stolen bases in his 38 games in Triple-A before his promotion. He is a top-10 prospect in all of baseball (according to MLB.com) and looks ready to make an immediate impact. In mixed leagues, he's a nice grab if still available, although there isn't a clear spot for him when Donovan returns. Emerson has a solid plate approach, but he did have a 27.2% K% in Triple-A. He has the tools to be a great fantasy contributor if he keeps his strikeouts under control and climbs to a more prominent spot in Seattle's batting order.

Las Vegas Athletics' SP J.T. Ginn recorded 10 strikeouts in 8 innings but took the loss in a 2-1 loss to the Angels on Monday, May. 18.

San Francisco Giants shortstop Willy Adames (hand) was pulled from Monday's game early against the hosting Arizona Diamondbacks after committing an error in the bottom of the fifth inning and taking a ground ball off of his right hand, according to The San Jose Mercury News' Justice delos Santos. Before injuring his hand, Adames had a solo home run (his fourth of the year) and a walk before Casey Schmitt shifted from left field to shortstop. Fantasy managers should consider the 30-year-old Dominican to be day-to-day heading into Game 2 of the series at Chase Field on Tuesday. Adames, like many other Giants hitters this year, has been a major disappointment, as he entered Monday's game in Arizona with a .234/.265/.356 slash line, .622 OPS, three homers, 13 RBI, 17 runs, and a stolen base in his first 46 games. Adames reached the 30-homer mark for the second straight season and the third time in the last four years in 2025, but he also hit just .225 (133-for-591) over 160 games played. Schmitt would most likely take over at the 6 going forward in San Fran if Adames' injury requires an extended absence.

San Francisco Giants left-hander Robbie Ray (quadriceps) left his start early on Monday night on the road against the division-rival Arizona Diamondbacks after fielding a comebacker that deflected off his quadriceps, according to Justice delos Santos of The San Jose Mercury News. delos Santos speculates that Ray's exit might not have been injury-related, though, after he allowed a whopping 10 runs (nine earned) on 11 hits (two homers) while walking two and striking out only one in 4 1/3 innings of work to take his sixth loss of the season. Either way, we'll be keeping a close eye on Ray's status in the coming days, and fantasy managers should be mindful that his next start could be up in the air. The 34-year-old former Cy Young winner and two-time All-Star came into Monday's start in the desert with a solid 3.04 ERA, 1.17 WHIP, and 49 punchouts in 50 1/3 innings across nine starts, but his nightmarish outing ballooned his ERA to 4.28. If Ray's leg injury isn't too serious, he could be one of the more popular trade targets this summer in the final year of his contract in San Fran.

San Francisco Giants outfielder Jung Hoo Lee (back) was pulled early from Monday's contest against the division-rival Arizona Diamondbacks with back spasms, according to Shayna Rubin of the San Francisco Chronicle. Before leaving the game, Lee went 1-for-2 at the plate out of the leadoff spot for the Gigantes. He was replaced in right field by Will Brennan. Lee should be considered day-to-day for now, and he'll almost certainly be absent from the starting nine for Game 2 of the series in Arizona on Tuesday against the D-backs. Fantasy managers will want to check back later to see if Lee's back injury is serious enough to require a stint on the 10-day injured list. The 27-year-old Japanese native probably is not rostered in most mixed fantasy leagues after combining for only 10 home runs, 63 RBI, and 12 stolen bases in 187 games in his first two years in the big leagues. Going into Monday's action, Lee was hitting .266 (47-for-177) with only three homers, 17 RBI, and 20 runs across 191 plate appearances. He's currently rostered in only 12% of Yahoo leagues.

New York Yankees infielder Jose Caballero (finger) played catch on Monday, manager Aaron Boone told Gary Phillips of the New York Daily News. Caballero has already been fielding in the last few days, but he's not throwing yet. Boone added that Caballero still has a chance to spend the minimum 10 days on the injured list, but the Yankees will see how the next few days go. The speedy 29-year-old fractured his right middle finger on May 10, but he is making good progress and could return from the IL when he's eligible on Thursday. The Yankees have already said that Caballero will reclaim starting duties at shortstop in the Bronx from Anthony Volpe when he returns to the Bronx. The native of Panama was playing a solid shortstop for the Yanks before his injury while slashing .259/.320/.400 with a .720 OPS, four home runs, 13 RBI, 13 stolen bases, and 18 runs scored in 135 at-bats. Caballero is mostly useful in fantasy leagues for his speed and positional versatility, as he's eligible at second, third, shortstop, and outfield in Yahoo leagues.

Kansas City Royals left-hander Cole Ragans (elbow) threw a 30-pitch bullpen session in Kansas City on Sunday that went as expected, according to MLB.com. If all goes well with Ragans when he plays catch on Monday and Tuesday, he will throw another bullpen on Tuesday. Ragans was placed on the 15-day injured list on May 8 with a left-elbow impingement, but he could return to KC's starting rotation by the end of May if he can avoid any setbacks. It's unclear as of now if the Royals will want to see Ragans go on a minor-league rehab assignment. Despite being limited to only 13 starts in 2025 due to injuries and dealing with the injury bug again early in 2026, Ragans is still rostered in over 90% of Yahoo leagues for his strikeout upside. He has a 1-4 record and 4.84 ERA (6.18 FIP) through his first eight starts of this season, but he also has 45 strikeouts and 23 walks in his 35 1/3 innings pitched. Ragans was money for fantasy managers in 2024, recording a career-high 223 strikeouts with a 3.14 ERA across 32 starts in his first full season with the Royals.

Milwaukee Brewers starting pitcher Brandon Woodruff (shoulder) threw a 30-pitch bullpen on Monday and is "tentatively" scheduled to face live hitters on Friday, per Adam McCalvy of MLB.com. Woodruff has been on the 15-day injured list with right shoulder inflammation since he experienced a drastic drop in his velocity during his start against the Arizona Diamondbacks on April 30. Woodruff was off to a solid start to 2026 before the injury, posting a 2-1 record with a 3.60 ERA, 1.03 WHIP, and 25 strikeouts across 30 innings (six starts). However, the 33-year-old has made just 29 starts since the start of the 2023 season and has an extensive history of shoulder issues. He appears to be making progress towards a return in early June, but Woodruff remains a major injury risk for fantasy managers going forward.

San Francisco Giants right-hander Logan Webb (knee) will make a minor-league rehab start later this week, according to the team. Alex Pavlovic of NBC Sports doesn't think that Webb will need more than one rehab start before coming off the 15-day injured list to rejoin San Fran's starting rotation. The 29-year-old landed on the 15-day injured list on May 9 with bursitis in his right knee, but barring a setback during his rehab start this week, his next start should be back with the Gigantes at some point next week. Webb's surface stats don't look all that great through his first eight starts of 2026, as he sits with a 2-4 record, 5.06 ERA (3.55 FIP), and 1.39 WHIP with 42 strikeouts and 15 walks in 48 innings pitched. The two-time All-Star also has a concerning hard-hit rate in the seventh percentile and an xwOBA in the 33rd percentile. Webb sits in the 37th percentile in strikeout rate, too, after leading the league with 224 strikeouts in 207 innings pitched in 2025. He also led the league with 210 hits allowed last year, and three straight seasons of 200-plus innings could be wearing on the eight-year veteran's arm.

Texas Rangers outfielder Wyatt Langford (forearm) did another "strength test" on his forearm on Sunday and recovered well on Monday, according to Shawn McFarland of The Dallas Morning News. McFarland writes that it's a good sign and is an improvement for Langford, although he'll still need to pass a few more tests before he starts his hitting and throwing progressions. The 24-year-old is progressing, but rather slowly, and at this rate, we might not see him return from the 10-day injured list until June. Once Langford is finally cleared to resume baseball activities, he figures to need at least a short minor-league rehab assignment, too. Fantasy managers might be running out of patience with the former fourth overall pick in 2023 out of the University of Florida. He still has immense power/speed potential, but injuries continue to be the story here. Langford has only played in 20 games so far in 2026 and has hit .238 (19-for-80) with a homer, four RBI, three steals, and nine runs. He had his first 20-20 season in 2025 with 22 homers, 62 RBI, and 22 steals in just 134 contests.

Tampa Bay Rays left-hander Steven Matz (elbow) came through his bullpen session on Sunday well and will come off the 15-day injured list to rejoin the starting rotation for a matchup on Wednesday against the division-rival Baltimore Orioles, according to Marc Topkin of the Tampa Bay Times. Matz has been out with left-elbow inflammation. Even though the matchup against the O's is a good one -- they currently rank 28th in baseball with a .699 team OPS -- Matz won't be a recommended fantasy streamer this week since he didn't go on a minor-league rehab assignment and will most likely be limited from a pitch-count perspective in his first game back from the IL. The 34-year-old veteran southpaw has posted a 4-1 record with a 3.86 ERA (4.81 FIP), 1.09 WHIP, and 28:13 K:BB in 37 1/3 innings across his first seven starts for Tampa this year in his return to a starting role. Matz has exceeded expectations so far, but he lacks high-end strikeout stuff, and his underlying metrics predict regression. It's likely why he's only rostered in 18% of Yahoo leagues.

Seattle Mariners right-hander Luis Castillo is slated to work as a piggyback reliever behind Mariners starter Bryce Miller on Tuesday against the Chicago White Sox, per Adam Jude of The Seattle Times. While Castillo has been one of the more dependable starting pitchers in baseball for nearly a decade, this move to the bullpen is a result of his brutal start to 2026. Across 44 innings (nine starts) so far this year, Castillo has recorded a 1-4 record with a 6.34 ERA, 1.57 WHIP, and 43 strikeouts. Miller opened 2026 on the injured list due to an oblique injury, but the combination of his return and Mariners right-hander Emerson Hancock's breakout may make it difficult for Castillo to rejoin the rotation. Even if the veteran gets another chance, his career-worst 13.4% K-BB rate could be an indicator that his time as a fantasy-relevant starting pitcher has come to a close.

Boston Red Sox outfielder Roman Anthony (wrist) is sore after taking some swings on Monday, so he will not swing again until after the off day on Thursday at least, according to Christopher Smith of MassLive.com. It's bad news for the 22-year-old former top outfield prospect as he attempts to return from the 10-day injured list due to a wrist injury. He has been out since early May and currently has no timetable for a return to Boston's starting lineup. Anthony will most likely need to go on a minor-league rehab assignment, too, so he probably is at least another week or two away from rejoining the big-league roster. The former second-rounder in 2022 teased his upside in a 71-game stint with the BoSox last year before ending the season on the IL, and now he's hurt again early in 2026. Despite hitting .229 (25-for-109) in his first 30 games this year with a homer, five RBI, and two steals, Anthony should be stashed in all fantasy baseball leagues for his high-end power/speed upside in Beantown. Until he's ready to return, Masataka Yoshida will continue to see regular at-bats against right-handed pitching. The Japanese native still has zero home runs in 77 at-bats, though, and offers a low fantasy ceiling.

Chicago White Sox catcher Kyle Teel (hamstring, knee) has been diagnosed with a sprained LCL in his right knee that is expected to keep him out for three to six weeks, per James Fegan of SoxMachine.com. Teel suffered the injury during a rehab game with Triple-A Charlotte while working his way back from a hamstring injury. The 24-year-old has yet to appear in an MLB game in 2026 and could now remain sidelined through June. Teel played well for the White Sox after making his MLB debut in 2025, hitting .273/.375/.411 with eight home runs, 35 RBI, 38 runs scored, and three stolen bases across 297 plate appearances. If he can get back to full health at some point in 2026, Teel profiles as a high-upside catcher option for fantasy managers to target on the waiver wire. In his absence, Drew Romo and Edgar Quero project to split catching duties for the White Sox.

Los Angeles Dodgers starting pitcher Tyler Glasnow (back) has yet to progress to throwing off a mound because of renewed discomfort in his back, per Sonja Chen of MLB.com. Glasnow is eligible to return from the 15-day injured list on May 22, but the team has already announced that he will not be ready at that point. The 32-year-old was off to a strong start to the 2026 season before getting injured, posting a 3-0 record with a 2.72 ERA, 1.10 WHIP, and 49 strikeouts across 39 2/3 innings (seven starts). However, injuries have been a major issue throughout Glasnow's career, as he's never made more than 22 starts in a season since breaking into the big leagues in 2016. If Glasnow's back troubles prevent him from throwing off a mound for much longer, he may require a rehab stint in the minors before he returns to the Dodgers.

Los Angeles Dodgers starting pitcher Blake Snell (elbow) will undergo a "nano-scope" procedure to remove loose bodies in his left elbow on Tuesday, per Alden Gonzalez of ESPN. Gonzalez notes that it's the same procedure that was recently performed on Detroit Tigers starter Tarik Skubal (elbow), and that the Dodgers are hoping for a relatively short return timeline for Snell. It's been a nightmare season to this point for Snell, who opened the year on the injured list due to a shoulder issue. The 33-year-old made just one start for the Dodgers before experiencing pain in his elbow that led to his current IL stint. Snell remains a high-upside fantasy starter when healthy, but the veteran left-hander has now made just 32 starts since the beginning of the 2024 season. He could be worth stashing in deeper formats or leagues with an IL spot. However, Snell's profile is riddled with injury risk at this point in his career.

Los Angeles Dodgers manager Dave Roberts said that he is planning for starting pitcher/designated hitter Shohei Ohtani to both hit and pitch during his start against the San Diego Padres on Wednesday, per Alden Gonzalez of ESPN. Ohtani has dominated on the mound so far this season, posting a 3-2 record with a 0.82 ERA, 0.82 WHIP, and 50 strikeouts across 44 innings (seven starts). However, the 31-year-old hasn't quite performed to his usual elite standard at the plate, as he entered play on Monday hitting .258/.385/.454 with seven home runs, 24 RBI, 30 runs scored, and six stolen bases across 201 plate appearances. The Dodgers have given Ohtani days off at the plate when he's been on the mound, but it appears as though the team will have him do both against San Diego.

The Baltimore Orioles announced that they reinstated infielder Jackson Holliday (hand) from the 10-day injured list on Monday and optioned catcher Maverick Handley to Triple-A Norfolk in a corresponding move. Holliday is back with Baltimore, but he wasn't included in the team's starting lineup for Monday's series opener in Tampa against the division-rival Rays. The 22-year-old will be Baltimore's starting second baseman now that he's back from a broken hamate bone in his right hand that required surgery back in spring training, and he should make his 2026 season debut in Game 2 of the series at Tropicana Field against the Rays on Tuesday. Although fantasy managers might be skeptical of Holliday after he hit just .176/.291/.284 with a .574 OPS in 22 minor-league rehab games, he deserves to be rostered in more than the 41% of Yahoo leagues that he currently is. Holliday was the former first overall pick in 2022 and made strides in his first full big-league season in 2025 with 17 home runs, 55 RBI, 17 stolen bases, and a .242/.314/.375 slash line in 149 total games.
