With the trade deadline in the rearview mirror, some prospects have changed organizations, others have been called up to replace departed veterans, while many are still waiting for their shot in the big leagues. This article features a mix of 10 prospects, some of whom just got the call this past week and others to keep an eye on as potential stash options who could make a difference over the remainder of the 2025 season.

Jakob Marsee, OF, Marlins (NR)
Marsee closed last week's stash article as a wild card to keep an eye on, and now he headlines this week's edition after a red-hot start to his big-league career. He was called up after the trade deadline to fill the roster spot vacated by Jesus Sanchez and has impressed through five games, going 6-for-12 with three doubles, a triple, a home run and three RBI. While that level of offensive production isn't likely to last, two factors point to Marsee remaining relevant.
First, he's already drawn five walks in just 17 plate appearances, showing off the same plate discipline and pitch recognition he demonstrated in the minors. Second, his top tool — speed — has yet to make an impact. Marsee has 46 steals in the minors this year but is 0-for-1 on stolen base attempts in the

He was called up after the trade deadline to fill the roster spot vacated by Jesus Sanchez and has impressed through five games, going 6-for-12 with three doubles, a triple, a home run and three RBI.

First, he's already drawn five walks in just 17 plate appearances, showing off the same plate discipline and pitch recognition he demonstrated in the minors. Second, his top tool — speed — has yet to make an impact. Marsee has 46 steals in the minors this year but is 0-for-1 on stolen base attempts in the majors so far, something that's almost certain to change soon. It's a tiny sample, and expecting him to keep hitting at this pace would be misguided, but his on-base skills and speed give him staying power even if the bat cools off.
Samuel Basallo, C, Orioles (#6, #1 C, #1 BAL)
Basallo has yet to make his MLB debut, but the signs suggest it's likely to happen this season. The Orioles traded away several regulars — Ryan O'Hearn, Ramon Laureano and Cedric Mullins — in prospect-focused deals, and Jake Rill of MLB.com reported that GM Mike Elias indicated it would be valuable for both Basallo and Dylan Beavers (more on him later) to get a taste of the majors in 2025.
Widely regarded as baseball's top catching prospect, Basallo has little left to prove in the minors, boasting a .998 OPS with 16 doubles, 22 home runs and 58 RBI through 70 games at Triple-A Norfolk. While everyday catching duties aren't realistic with Adley Rutschman entrenched behind the plate, there's little reason for the Orioles not to get Basallo's bat into the lineup regularly during the final stretch of a disappointing season.
Dylan Beavers, OF, Orioles (#104, #23 OF, #4 BAL)
The trade deadline worked out perfectly for Beavers, as the departures of Ryan O'Hearn, Ramon Laureano and Cedric Mullins have opened a clearer path to big-league playing time. Combine that with Mike Elias specifically naming Beavers as someone who could benefit from MLB experience this season and he becomes a top stash candidate.
Beavers' strong 2025 campaign has kept rolling, as he hit 11-for-28 with five homers in his previous seven games. For the season, the outfielder is slashing .310/.423/.539 with a .962 OPS, 13 doubles, two triples, 18 home runs, 22 stolen bases and 48 RBI across 86 games for Triple-A Norfolk. His tools may take time to fully translate to the next level, but he brings all five to the table.
Logan Henderson, SP, Brewers (#65, #17 SP, #6 MIL)
In most other organizations, Henderson would've spent the majority of the season in the majors, but due to the Brewers' deep pool of pitching talent, he's spent most of this year in the minors. Milwaukee recalled him to fill a rotation spot Sunday following Nestor Cortes' departure and Jacob Misiorowski's tibia injury.
Henderson made the most of his opportunity, tossing 4.1 innings of one-run ball against the Nationals. Through five MLB starts (25.1 innings), he owns a 1.78 ERA, 0.99 WHIP and 11.7 K/9, significantly outperforming his already strong Triple-A Nashville numbers (a 3.59 ERA, 1.11 WHIP and 10.1 K/9 across 16 starts). Expecting him to maintain that elite production in the majors would be overly ambitious, but the 23-year-old is a polished arm who's proven he can thrive when given the chance.
Bubba Chandler, SP, Pirates (#19, #4 SP, #2 PIT)
The Pirates may not have moved as many starting pitchers as expected at the deadline, but Bailey Falter's departure does create an opening in the rotation — one that top prospect Bubba Chandler could fill. Carmen Mlodzinski, who's made nine starts this year, is currently on the major-league roster but has recently worked more out of the bullpen, while Thomas Harrington's struggles make him an unlikely candidate to leap ahead of Chandler.
Chandler hasn't been sharp in his past two outings, giving up eight earned runs, three homers and five walks over 10 innings. Still, those struggles shouldn't keep the Pirates from giving him a shot. His season numbers — a 3.69 ERA and 1.40 WHIP across 92.2 innings (22 starts) for Triple-A Indianapolis — don't jump off the page, but the right-hander's high-octane fastball and swing-and-miss ability (11.0 K/9) make him one of the most electric arms in the minors. While command remains a concern (4.5 BB/9), Pittsburgh isn't in contention, and with a rotation spot available, giving Chandler a look in the majors down the stretch makes plenty of sense.
Mick Abel, SP, Twins (#114, #36 SP, #5 MIN)
Abel's value for the rest of the season received a major boost after the righty was traded from the contending Phillies to the rebuilding Twins. While Minnesota didn't immediately insert Abel into its big-league rotation, the current state of the staff — with few stable options behind ace Joe Ryan — suggests a call-up could be on the horizon.
Abel pitched well for Triple-A Lehigh Valley prior to the trade, logging a 2.31 ERA and 1.16 WHIP over 13 starts (74 innings), and he impressed in his Twins organizational debut with five scoreless frames for Triple-A St. Paul on Sunday. The 2020 first-round pick leans on a powerful fastball and mixes in both a curveball and slider to keep hitters off balance. Though his initial stint in the majors with Philadelphia didn't go smoothly (5.04 ERA in 25 innings), much of that came down to control issues and home-run trouble. Abel still needs to sharpen his command to stick in a big-league rotation, but his minor-league track record and the clear opening in Minnesota make him a name to watch closely.
Carter Jensen, C, Royals (#99, #9 C, #1 KC)
Jensen earns a spot on this list thanks to both his strong individual performance and the growing opportunity within the Royals' roster. Kansas City dealt Freddy Fermin at the trade deadline, elevating Luke Maile to the backup catcher role behind Salvador Perez. While Maile has been solid in limited action (17 plate appearances), the 34-year-old career backup isn't likely to block a top prospect like Jensen for long.
Promoted from Double-A Northwest Arkansas to Triple-A Omaha on June 24 after posting a .781 OPS with 19 extra-base hits in 69 games, Jensen has taken a step forward at the higher level. In 26 Triple-A contests, he's slashing .253/.366/.558 with a .924 OPS, five doubles and eight homers. Though the left-handed hitter has swing-and-miss in his game, he also displays a good eye at the plate — a skill that will help him settle in the majors once he gets the call-up.
Bryce Eldridge, 1B, Giants (#13, #1 1B, #1 SF)
Eldridge joins the stash list as one of baseball's top hitting prospects and could get a shot at the majors if the Giants continue to slide out of playoff contention. Rafael Devers is locked into either first base or designated hitter long-term, and while Wilmer Flores has been a consistent presence in the lineup for several years, the veteran is currently dealing with injuries and carrying a sub-.700 OPS, potentially opening the door for Eldridge.
The 20-year-old brings massive raw power to the table, with 18 home runs across 66 games between Double-A Richmond and Triple-A Sacramento this season. That total doesn't fully capture the kind of strength Eldridge possesses. There's a significant amount of swing-and-miss in his approach, as evidenced by strikeout rates in the mid-to-high 20s throughout his time in the minors, and those issues likely won't disappear in the big leagues. Still, his ability to crush the baseball makes him a high-upside bat worth tracking.
Emmanuel Rodriguez, OF, Twins (#44, #11 OF, #3 MIN)
The Twins' deadline fire sale created plenty of opportunities for young players, and Rodriguez would likely already be in the majors if not for the right oblique strain that landed him on the shelf July 21. With Byron Buxton (ribs) sidelined, Austin Martin and Alan Roden are seeing time in the outfield, but once Rodriguez is healthy, he could be next in line for a call-up.
The 22-year-old has been productive when available, slashing .254/.411/.428 with an .839 OPS in 43 games for Triple-A St. Paul. His 13 extra-base hits undersell his elite raw power, but his 19.8 percent walk rate highlights the advanced plate discipline that sets him apart. Strikeouts have been a concern throughout his minor-league career, and they'll likely follow him to the majors, but his ability to generate hard contact should offset some of those swing-and-miss issues. Health will be the key, but Rodriguez could make a strong case for a promotion once his oblique is fully healed.
George Klassen, SP, Angels (#274, #97 SP, #6 LAA)
In most organizations, Klassen likely wouldn't be in the mix for a big-league debut this season, but the Angels' aggressive approach makes him a deep sleeper worth keeping an eye on. While the team stayed relatively quiet at the trade deadline, they're not necessarily positioned to make a serious playoff push, and Jack Kochanowicz doesn't appear to have a firm grip on the fifth rotation spot.
Klassen's surface-level stats at Double-A Rocket City — a 5.84 ERA and 1.45 WHIP across 69.1 innings in 17 starts — aren't exactly impressive, but his underlying numbers tell a more promising story. His 3.45 FIP better reflects his performance, and his 10.8 K/9, though a career low, remains impressive. His near triple-digit fastball is a weapon, but it's his breaking stuff, particularly his sharp slider and curveball with strong movement, that stand out. While Caden Dana and Sam Aldegheri are also candidates to join the rotation, Klassen's upside makes him the most intriguing of the group.
