Could Franklin Arias Make His MLB Debut in 2026?
Though Boston Red Sox shortstop prospect Franklin Arias went 0-for-4 on Sunday, he's still riding a 12-game on-base streak after getting hit by a pitch in the game, and he has now reached base safely in 37 of 41 games at Double-A Portland. The 20-year-old's 1.026 OPS is second-best in the Eastern League, second only to Jonah Cox, who was recently promoted straight to the majors by the Giants. Hitting .331 with a low 12.3 percent strikeout rate, the 5-foot-11 Venezuelan seems destined for Triple-A in the near future, and with a good showing there, he could be in the mix for a debut in the majors later this season. Given his age (Cox is four years older than Arias), a Cox-like promotion straight to the majors is unlikely, but with Trevor Story (hernia) out for several more weeks at a minimum, it wouldn't be totally out of the question with how good Arias has looked. Fantasy managers should keep the youngster on their radar, as he could quickly become a stash target.

Cole Carrigg Remains a Must-Stash for Stolen-Base Upside
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.

Coleman Crow Holding His Own in MLB Debut, Worth an Add in Deeper Leagues?
Milwaukee Brewers rookie right-hander Coleman Crow made his MLB debut earlier this season and has shown real promise in limited action. The 25-year-old prospect has a 3.14 ERA and 0.98 WHIP across 14 1/3 innings in three big-league starts, striking out eight while walking just three hitters. After performing well at Triple-A Nashville earlier this season, Crow has earned a look in Milwaukee's rotation and has the stuff to stick around if he continues to command his pitches. Crow was initally called up to replace Logan Henderson, who was shifted to the 15-day injured list with a back injury. He's still widely available in most leagues and represents a high-upside speculative add for managers in need of pitching. If you have the roster space in deeper leagues or are looking for a young arm with upside, Crow is worth a flier as he should remain in the Brewers rotation for the time being.

Is Thomas White a Stash Option Without Clear Timetable for Return?
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.

Kirby Yates Emerging as Priority Closer to Roster in Angels Bullpen?
Los Angeles Angels veteran closer Kirby Yates is starting to look like a sneaky waiver wire priority for managers chasing saves. The 39-year-old has a track record of closing (98 career saves entering 2026) and has already picked up his 99th save in limited action this season. With Robert Stephenson and Ben Joyce dealing with injuries early on, Yates has a clear path to high-leverage work and save chances under manager Kurt Suzuki, who has been vocal about his trust in the veteran. The right-hander opened the season on the shelf with a knee injury, which allowed Ryan Zeferjahn and Jordan Romano (who was designated for assignment in late April) to operate as the primary ninth-inning options. With limited competition in this current bullpen, Yates has a clear path to quickly claim this role. During the 2024 season, Yates showed promise in the closer role for the Rangers, tallying 33 saves with a 1.17 ERA. Even though he has endured some growing pains since returning from injury (4.32 ERA over 8 1/3 frames), his high-leverage experience gives him the edge to emerge as the ninth-inning option in this bullpen.

Walker Jenkins Nearing Rehab Assignment, Worth Stashing Ahead of Return?
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.

Spencer Horwitz Swinging a Hot Bat, Entering Must-Add Territory?
Pittsburgh Pirates first baseman Spencer Horwitz is putting together a productive season and remains a strong waiver wire target for managers needing corner infield help. The 28-year-old is hitting .289 with a .389 OBP and .858 OPS in 173 at-bats, showing excellent plate discipline with a low strikeout rate and strong walk rate. He's been especially hot in May, hitting safely in 17 of his last 21 games at one point, and has already chipped in seven home runs on the season. Horwitz has earned an everyday role in the Pittsburgh lineup, playing first base and typically batting leadoff against right-handed pitching. He's still available in a large percentage of leagues and offers a nice blend of average, on-base skills, and emerging power. If you're looking for a steady, high-floor option at corner infield, Horwitz is worth picking up.

Charlie Condon Riding 12-Game Hitting Streak, MLB Debut Imminent?
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.

Gavin Sheets Worth an Add for Power Upside
San Diego Padres first baseman/outfielder Gavin Sheets is putting together a very productive season and could be a worthwhile waiver wire pickup for managers needing corner infield or outfield help. In just 163 at-bats, the lefty has already hit nine home runs with 23 RBI and is posting a strong .807 OPS. He's been very effective against right-handed pitching, posting a .879 OPS with an elite .529 SLG. While his playing time can be inconsistent as a platoon bat, when he's in the lineup, he's been producing at a high level. Under the hood, Sheets is impacting the ball quite hard, as evidenced by his 71st percentile 45.5% hard-hit rate and 82nd percentile 74.8 mph average bat speed. Sheets is still widely available in most leagues, sitting at just 23% rostered on Yahoo, and offers a nice combination of power and on-base skills. If you're looking for a depth outfielder or corner infielder with above-average power, he's worth a look.

Jake Burger Emerging as Priority Pickup for Power Upside
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 looking for some cheap pop down the stretch, Burger is a strong add right now as he has begun to find his footing.

Braden Montgomery Breaks Out of Slump, Remains Firmly on Stash Radar
Chicago White Sox outfield prospect Braden Montgomery broke out of a recent slump with a strong four-game stretch at Triple-A Charlotte that saw him go 8-for-16 (.500) with two doubles, a home run, four RBI, seven runs scored, and a stolen base. Perhaps most impressive of all was that the switch-hitter did not strike out once in those four games, his longest stretch of the season without a strikeout, while also drawing three walks. Chicago's second-ranked prospect is performing admirably since earning a promotion to Triple-A, hitting .281 with seven doubles and three home runs in 23 games for the Knights, getting on base at a .366 clip thanks to a solid 10.9 walk rate, and he's also swiped two bags. At this rate, the former first-rounder looks poised for a midseason call-up to the majors, and with a blend of contact, power, and speed, the 23-year-old makes for a stashworthy fantasy asset in deeper leagues.

Josh Hader Set to Return from Injured List on Tuesday
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.

Francisco Alvarez Starting a Rehab Assignment on Tuesday
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.

Corey Seager Starting Rehab Assignment on Tuesday
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.

Gleyber Torres Returning From Injured List on Tuesday
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.
