Texas Rangers first baseman Jake Burger is starting to look like a legit waiver wire target for managers needing corner infield help. The 30-year-old has already mashed 10 home runs with 37 RBI in just 215 at-bats, and he's shown real signs of a resurgence this year. After a rough April, Burger has been much better in May, with a .284 average, improved plate discipline, and a surging pull rate that has led to more hard contact and higher home run totals. He's been hitting in the middle of a decent Rangers lineup and continues to post elite exit velocities. He's still only rostered in 30% of Yahoo leagues in most formats, which feels way low for a guy with this kind of raw power. If you're thin at 1B or just looking for some cheap pop down the stretch, Jake Burger is a strong add right now.

Houston Astros closer Josh Hader (biceps) is being activated off the injured list on Tuesday, manager Joe Espada confirmed. Hader had been sidelined since before Opening Day with left biceps tendinitis (he also dealt with shoulder issues late last season). He's progressed through his rehab without setbacks and is now ready to rejoin the big-league bullpen. While the Astros are expected to be cautious with his workload in the early going, Hader should quickly settle back into his role as the primary closer. For fantasy managers, this is a significant boost in saves leagues, especially if you've been streaming or holding onto a committee. Keep an eye on his first few appearances to see how the Astros deploy him, as they may slightly monitor his usage. With Hader set to return, fantasy managers should expect Bryan King, Enyel De Los Santos, and Bryan Abreu to operate as the primary setup options.

Colorado Rockies outfield prospect Cole Carrigg has cooled off somewhat over his last five games, going 3-for-18 (.167) over that stretch, but two of his three hits went for extra bases (doubles), he continued to get on base with a 4:5 BB:K, and stole three bases during that time. For the season, the Rockies' sixth-ranked prospect is slashing an impressive .345/.412/.532 at Triple-A Albuquerque, with five home runs and 29 steals. A strikeout rate of just 14.8 percent and a 9.6 percent walk rate show a disciplined approach, and he should be a strong consideration for a major league debut in the coming weeks. The switch-hitter's most appealing attribute is his speed, having stolen 99 bags between 2024 and 2025, but with 32 home runs combined in those two seasons, there is certainly some pop in his bat as well, and he is a career .283 hitter in the minors, so the 6-foot-2 slugger has a fantasy-friendly skillset. Given his proximity to the majors, Carrigg should be considered one of the top prospect hitters to stash in fantasy leagues, especially for managers searching for steals.

Miami Marlins pitching prospect Thomas White (shoulder) was placed on the 7-day injured list on May 20 (retroactive to May 19), but has yet to come off the IL and is not listed as the probable starter for any of Triple-A Jacksonville's upcoming games, so a return timetable remains unclear. Marlins president of baseball operations Peter Bendix stated last week that the southpaw was dealing with a "bit of shoulder thing" and that it was not something "particularly concerning," but there has been no update to his status since then. Regardless, assuming it is indeed a minor issue, the team's top-ranked prospect might need a short rehab assignment before rejoining Jacksonville, so a mid-to-late June return seems like the most optimistic scenario for the lefty. The 6-foot-5 hurler was flashing strong strikeout potential before the injury, with a 30.9 percent K% through five Triple-A starts, but the team will likely want to see some improved command upon return from the IL, as he'd walked 15 batters and hit two batters in 18 2/3 innings pitched. With his strikeout upside, though, and the likelihood of a debut by midseason, the 21-year-old will likely be a top pitcher to stash once he returns to the mound in some capacity.

Colorado Rockies corner infield/outfield prospect Charlie Condon's 31-game homerless stretch feels like a distant memory after the week and a half that he's had for Triple-A Albuquerque, blasting four home runs in his last seven games, including a walk-off winner in his latest contest. The power surge is part of a longer 12-game hit streak during which time the Rockies' second-ranked prospect has gone 16-for-45 (.356), which includes not only those four home runs, but also seven doubles, boosting his season-long slugging percentage to .471 with eight total home runs and a .262 batting average. A strong 15.1 percent walk rate has also buoyed a robust .391 on-base percentage. A high strikeout rate may limit the 23-year-old's batting average whenever he gets to the majors, but the power should play well at Coors Field, and a debut there could happen in the coming weeks. The 6-foot-5 power hitter is still a solid stash option in deeper leagues, especially for managers in search of home runs.

Minnesota Twins outfield prospect Walker Jenkins (shoulder) is making progress in his return from a Grade 2 AC joint sprain in his left shoulder as he's reportedly begun to take swings off a hitting machine and could be ready to start a rehab assignment next week, according to Twins general manager Jeremy Zoll. The Twins' top-ranked prospect hasn't played in a game since May 3, but had begun to hit his stride at the plate at Triple-A St. Paul, going 9-for-21 (.429) with four doubles, a home run, a 6:4 BB:K, and two steals during a six-game hit streak before hitting the injured list. For the season, the former fifth-overall draft pick is slashing .256/.396/.389 with two home runs, five steals, and more walks (19) than strikeouts (18). If the 21-year-old can get back on track once he returns to the St. Paul lineup, a major league debut could happen by August, so the 6-foot-3 slugger could become a top hitter to stash in the weeks ahead.

The New York Mets plan to have catcher Francisco Alvarez (knee) start a minor-league rehab assignment on Tuesday with Triple-A Syracuse, manager Carlos Mendoza told Andrew Tredinnick of The North Jersey Bergen Record. Alvarez has been making good progress since having surgery to fix the meniscus in his right knee just several weeks ago. Initially, the Mets estimated that he would be out for around eight weeks. They will most likely slow-play Alvarez in the minors, but barring a setback, it looks like he's going to beat his initial timetable by quite a bit. Until he returns, the Mets will continue to roll with veteran Luis Torrens as their primary backstop, with Hayden Senger backing him up. Alvarez was hitting .241/.317/.392 with a .710 OPS, four home runs, 10 RBI, and 12 runs scored in 112 at-bats at the time of his knee injury in mid-May. The oft-injured Venezuelan catcher has provided above-average pop in the past, but his lengthy injury history makes him hard to trust in single-catcher fantasy leagues. Alvarez is currently rostered in only 15% of Yahoo leagues.

Detroit Tigers second baseman Gleyber Torres (oblique) will be activated from the 10-day injured list on Tuesday and return to the starting lineup for the contest against the Tampa Bay Rays and left-hander Steven Matz, manager A.J. Hinch told MLB Network Radio. The Tigers are ready to bring Torres back after he played in just two minor-league rehab games. The 29-year-old has been out since early May due to a strained left oblique, but now that he's back, he'll return to starting duties at the keystone in Motown, pushing Hao-Yu Lee and Zach McKinstry to utility roles. Lee could end up being sent to Triple-A Toledo. Torres was hitting .259/.389/.328 with a .716 OPS, only two home runs, 11 RBI, and 18 runs scored in 116 at-bats this year at the time of his oblique injury. He offers very modest power and speed as middle-infield depth in deep-mixed fantasy leagues. Torres is mostly valuable for his plate discipline, contact-oriented approach, and on-base skills.

Texas Rangers shortstop Corey Seager (back) is starting a minor-league rehab assignment at Double-A Frisco on Tuesday, according to the team. He is scheduled to bat second and play shortstop for the Rough Riders on Tuesday. Seager is one step closer to returning from inflammation in his lower back that has kept him out since May 13. But if he doesn't have a setback with his back this week, he could be reinstated from the 10-day injured list later this week or the weekend. Ezequiel Duran has been filling in nicely at the 6 for the Rangers with Seager sidelined, and he'll go back to more of a super-utility role for the team once Seager is back on the active roster. Seager was hitting a disappointing .179 (28-for-156) to begin the 2026 season before injuring his back, but he also had seven home runs, 20 RBI, 22 runs scored, and a steal. Despite durability concerns in his early-30s, Seager is a must-roster fantasy SS. He's only available in 10% of Yahoo leagues.

Philadelphia Phillies third baseman Alec Bohm is off to a rough start to the 2026 season, hitting .210/.271/.335 with six home runs, 24 RBI, and 17 runs scored across 221 plate appearances. However, the 29-year-old's overall line is dragged down by a brutal showing in March and April, when he hit .151 with a .426 OPS across 119 plate appearances. Bohm's production bounced back to his established norms in May, as he slashed .277/.333/.439 with five home runs, 11 RBI, and 11 runs scored across 102 plate appearances last month. With a 6.4% career barrel rate and 18 stolen bases across 774 career MLB games, Bohm offers limited power and speed upside for fantasy managers. Still, Bohm remains a fixture in the Phillies' everyday lineup, and he's hit no lower than fifth in the batting order since May 13. As long as his early-season struggles are behind him, Bohm should provide batting average and quality counting stats for fantasy managers the rest of the way in 2026. In deeper leagues, Bohm's May bounce-back makes him a worthy waiver wire target despite his ugly overall slash line.

Across 67 innings (12 starts) so far in 2026, Washington Nationals starting pitcher Foster Griffin has recorded a 6-2 record with a 3.76 ERA, 1.15 WHIP, and 65 strikeouts. The 30-year-old has cooled off a bit in recent weeks after a red-hot start to the season, allowing 17 earned runs over his last 20 1/3 innings (four starts). The long ball has been an issue for Griffin, as he currently owns a 1.75 HR/9. Still, Griffin has limited opponents to a 37.8% hard-hit rate and owns a quality 15.7% K-BB rate. There's also reason to think he's been a bit unlucky to give up homers as often as he has, as his 18.1% home run to fly ball rate is well above league average. Griffin may not offer crazy upside, but he remains a solid starting pitcher streamer for fantasy managers to target on the waiver wire.

San Francisco Giants reliever Caleb Kilian had a rough outing on Friday in Colorado against the Rockies, allowing two homers and five earned runs across 2/3 of an inning. However, even with the recent blow-up, Kilian's overall numbers for the season are strong. Across 26 innings (24 games), the 29-year-old has pitched to a 3.86 ERA and 1.15 WHIP with 29 strikeouts and three saves. Kilian's average fastball velocity currently sits at 96.9 miles per hour, and he's struck out 26.9% of the batters he's faced. The Giants have utilized multiple relievers in the ninth inning this season, so fantasy managers should not expect Kilian to see every San Francisco save opportunity. Still, the hard-throwing right-hander has emerged as a quality source of both saves and strikeouts for deep-league fantasy managers to target on the waiver wire.

Athletics pitching prospect Gage Jump made his MLB debut last Tuesday against the Seattle Mariners, allowing nine hits and four earned runs while striking out five across five innings of work. While the 23-year-old's first start in the majors was a bit of a struggle, he remains a potentially intriguing starting pitching option for fantasy managers. Across 38 innings (nine starts) with Triple-A Las Vegas before his promotion, Jump pitched to a 4.50 ERA and 1.47 WHIP with 56 strikeouts. Particularly given that he will be making his home starts in the hitter-friendly Sutter Health Park, Jump may not provide much value in the ERA and WHIP categories for fantasy managers. However, the young lefty carries significant strikeout upside after posting strikeout rates of 33.1% and 28.4% in the minors in 2026 and 2025, respectively. Fantasy managers in need of whiffs may want to consider targeting Jump on the waiver wire ahead of a potential breakout.

Since being acquired from the Tampa Bay Rays in early May, Minnesota Twins reliever Yoendrys Gomez has emerged as a key piece in his new team's bullpen. Across 11 1/3 innings (13 games) with Minnesota, Gomez has pitched to a 0.79 ERA and 0.88 WHIP with 14 strikeouts and two saves. The 26-year-old has also finished six games on the mound for the Twins. Minnesota has opted for a committee approach to the ninth inning in 2026, as 11 different relievers have earned saves for the team so far this season. However, Gomez and veteran lefty Taylor Rogers are the only Twins pitchers currently on the active roster with multiple saves, and Rogers has struggled to a 4.15 ERA and 1.57 WHIP in his 25 appearances. If Gomez can continue his strong work, he could take hold of the closer role in Minnesota. He profiles as a worthy waiver wire target in deeper leagues.

Seattle Mariners right-hander Bryce Miller had his 2026 season delayed by an oblique strain that he suffered in spring training. However, the 27-year-old has been effective since returning in mid-May, recording a 1-0 record with a 1.71 ERA, 0.86 WHIP, and 20 strikeouts across 21 innings (four games). While Miller made one appearance as a reliever as Seattle manages its impressive rotation depth, he's pitched at least five innings in all four of his outings. The young right-hander owns an impressive 21.5% K-BB rate that is buoyed by his elite 3.8% walk rate. After posting a 5.68 ERA across 90 1/3 innings in 2025, Miller appears to be back to the form he displayed in 2024, when he logged a 2.94 ERA across 180 1/3 innings. In any leagues where he's not already rostered, Miller should be a priority waiver wire target with upside for fantasy managers.

Los Angeles Angels relief pitcher Kirby Yates gave up one earned run on two hits in the ninth inning on Monday, taking the loss as his team fell to the Rockies, 9-8. Yanes gave up a single to Kyle Karros and a double to Jake McCarthy before the game-winning sacrifice fly from T.J. Rumfield. Yates was entering the game in a non-save situation after a wild eighth inning, in which the Rockies scored five times to take the lead, and the Angels answered with two runs to tie the game back up when Yates entered. The 39-year-old righty has a 4.32 ERA and 4.04 FIP in his nine games this season, and before Monday, he allowed just one run in his previous six appearances. He has only had a single save this season since the Angels don't present a ton of opportunities, but he'll likely remain the top closer for now in the absence of any other experienced options at the back of the bullpen.

Detroit Tigers relief pitcher Kyle Finnegan was expected to step in as the team's fill-in closer while Kenley Jansen (pelvis) is on the injured list, but that wasn't how the script unfolded on Monday. Finnegan entered an 8-5 game in the seventh inning in a high-leverage spot against the top of the Rays' order. He allowed a single to Yandy Diaz, but struck out Jonathan Aranda, and then induced an inning-ending double play from Richie Palacios. The eighth and ninth innings didn't go smoothly for Beau Brieske and Will Vest, but the team held on for a wild 10-9 win, with Vest earning the save. Finnegan could still end up getting short-term save opportunities, especially with his effective outing on Monday, but the full-time closer job isn't going to be his alone. He's a speculative add in most leagues at this point, but he brings intriguing upside for as long as Jansen is unavailable.

Texas Rangers relief pitcher Jacob Latz earned a save for the second day in a row on Monday night, closing out his team's 2-1 win over the Cardinals. Latz worked a clean ninth inning, picking up back-to-back strikeouts to end the game. The 30-year-old lefty has a 2.00 ERA and 0.59 WHIP in his 27 innings this season, totaling 26 strikeouts. He has picked up three saves and a win in his last four appearances and has emerged as the clear leader for save situations. He has worked back-to-back days, so his availability for Tuesday is uncertain, but if you need saves, Latz is one of the best options you can pick up from the waiver wire.

Detroit Tigers relief pitcher Will Vest closed out his team's 10-9 win over the Rays on Monday night, earning his first save of the season. The 30-year-old righty entered a messy situation in the eighth inning with the bases loaded and one out while his team was holding a 10-5 lead. He gave up a double and a single, allowing four runs to score, but preserved the lead. Things went much more smoothly for Vest in the 1-2-3 ninth inning, finishing with back-to-back strikeouts. He was charged with one run in his 1 2/3 innings, but he still lowered his ERA to 7.23 on the season. His 3.45 FIP and 3.35 xERA indicate he has pitched better than his elevated ERA indicates, but he is still very high-risk after his rough start to the season. Even though he's risky, he does have enough upside to consider from the waiver wire, though, since the Tigers are without closer Kenley Jansen (pelvis) and saves should be available. Vest got the job done on Monday and does have potential to be a short-term source of saves for deep leagues.

Seattle Mariners first baseman Josh Naylor smashed a solo home run to tie the game in the seventh inning of Monday's extra-inning win over the Mets, but he left the game with back spasms before the bottom of the inning. He was replaced at first base by Patrick Wisdom, and the Mariners could also use Luke Raley at the position if Naylor misses any games due to the issue. On the season, Naylor is hitting .254 with six home runs, 25 RBI, and 12 stolen bases in his 57 games. He has a .301 wOBA, which is well below his career average, but he had hit safely in seven of his last eight games with a .303 batting average and .319 wOBA before the injury. As long as he avoids the injured list, he's still worth holding in most leagues at this point, although there could be some extra value for Wisdom and Raley in the next few days if Naylor is sidelined.
