MLB trade season has officially kicked into high gear with contenders looking to add to their rosters for the stretch run ahead and rebuilding teams aiming to stockpile young players with an eye to the future before Thursday’s 6 p.m. ET deadline arrives.
As the moves go down, you can probably form your own opinion of the MLB veterans headed to new teams, but it’s much more difficult to figure out what to make of the minor leaguers who have moved.
Don’t worry, we’ve got you covered. Here’s our running ranking of every notable prospect who was dealt during July sorted by tiers using my Future Value grades so you can see where they slot in an MLB top 100 list or your team’s farm system ranking.
This story will be updated with top prospects headed to new teams added to the list with every new deal, so come back every time a move goes down to see which stars of tomorrow are on the move this month.
40+ FV tier
Acquired from Seattle Mariners in Josh Naylor deal
A 2023 11th-rounder out of Texas A&M, Garcia was a sleeper in the Seattle system who broke through as a starter in 2024. This season, he was moved into a full-time relief role, leading to his big league debut earlier this month.
He has an upper-body-reliant delivery with very short extension and a near-sidearm slot that nonetheless creates a lot of velocity, with his fastball peaking at 100.4 mph this season and living at 95-98 mph with his plus sinker. He also mixes in an 88-90 mph cutter and 84-86 mph sweeper that are both plus pitches. Garcia’s fastball command improving and the cutter continuing to be a useful weapon against righties are keys to him becoming a late-inning reliever.
Acquired from Milwaukee Brewers in Danny Jansen deal
Areinamo is listed at 5-foot-8, is a below-average runner and has below-average range that will keep him from being a long-term everyday shortstop; he’s already splitting time between shortstop and second/third base in High-A this year. Those facts limit his upside a bit, though he has an average arm and can catch the ball when he gets to it. The sales pitch is that he’s growing into fringe-to-average power with a sometimes wild swing but manages to also post plus contact rates. The offensive hesitation is that Areinamo, as his swing suggests, can get a little wild chasing pitches out of the zone, even if his standout bat control bails him out of some bad swing decisions. With some progress on his chase rate, Areinamo could move from a projected platoon guy to a lower-end starter at second base.
40 FV tier
Acquired from New York Yankees in Ryan McMahon deal
Herring signed for $800,000 after being selected in the sixth round of the 2024 draft. He made only one start over two seasons at LSU but showed starter traits. Through 16 appearances as a starter this year, pitching across both Single-A levels, that theory has mostly held up.
His 88-92 mph heater touches 94 and looks as if it’ll be a fringe-to-average pitch, while his slider is above average and his changeup (which should be used more often) also flashes above average. He’ll move up to the 40+ FV tier with a little more bulk of performance and/or a strong finish/promotion in Double-A.
Acquired from New York Mets in Gregory Soto deal
Aracena was a low-profile international signee, getting a $70,000 bonus in 2022 out of the Dominican Republic. He sat 90-94 mph for his first two pro seasons, then his velo exploded in 2024 to 95-98, hitting 100 mph. This year he’s been even a bit higher, sitting 96-99 and hitting 101 mph at 20 years old as a starter in Single-A.
The reason he isn’t ranked higher is his command is below average to the point that his likely career outcome is as a reliever. His fastball also plays below its velocity right now due to his command issues and higher arm slot, which creates a nonideal plane and a cutting action to the pitch. His 89-95 mph slider (possibly a cutter and slider that run together) is nasty, a clear plus pitch, while his changeup is rarely used and rudimentary.
The raw ability here is impressive and Aracena is young and athletic enough to get another year or two to prove he can start, but he also has late-inning potential as a reliever if that doesn’t work out. Aracena will move into the 40+ FV tier with either a tick more of command, developing a legitimate changeup or just keeping his head above water performance-wise as a starter in High-A.
Acquired from the Detroit Tigers in Chris Paddack deal
Jimenez is a 19-year-old, switch-hitting catcher playing in Rookie ball who has a solid chance to stick behind the plate long term, but as you’d guess, he still has some defensive work to do. He’s a slightly above-average framer (particularly to his glove side) and has above-average arm strength (catching 34% of baserunners this year) but is a below-average blocker of pitches in the dirt.
He’d benefit from getting more agile behind the plate, but the athleticism is there to do so: Jimenez is a solid-average runner right now despite a stout 5-foot-9 frame. His raw power projects as fringe to average given his lack of physical projection, though he has solid ball flight (think 15ish homers at peak), with a grade more power as a left-handed hitter. Jimenez’s contact and on-base skills grade about average, so the sales pitch here is an overall average offensive threat, which is enough to warrant playing him at other positions to get his bat in the lineup as a platoon option, but also hoping he can progress in all phases enough to become a primary catcher.
6. Ashton Izzi, RHP, Arizona Diamondbacks
Acquired from Seattle Mariners in Josh Naylor deal
Izzi was a classic projection righty who signed for $1.1 million after being selected in the fourth round of the 2022 draft out of an Illinois high school.
He has delivered on that projection, with his average fastball velo having crept up from 93.1 to 94.0 to 94.5 in his three pro seasons. His four-seamer is a solid-average pitch, while his slider can get to average with slightly better locations and his sweeper is an above-average pitch, maybe plus.
The issue is Izzi’s sinker; although it has a fine velocity/movement combination, it is too center-cut in the zone and has been hammered by hitters while being used almost as much as his four-seamer. He also doesn’t use his changeup much — but probably should, especially as he dials back his sinker. With some progress in his mix and locations, this is a No. 4 starter package, but Izzi is more of a long reliever as currently constituted.
Acquired from Kansas City Royals in Randal Grichuk deal
Hoffmann was a 12th-round pick out of Illinois in the 2021 draft who was traded to the Royals in 2022 and finished the season in Double-A, beating predraft expectations. He was seen as a potential back-end starter at that point, but moved to full-time short relief this season en route to making his big league debut.
His mid-90s fastball is a solid-average pitch that plays up due to his funk and deception, and his main weapon is a plus changeup that tunnels well to the bottom of the zone. His slider is a clear third pitch and is fringy, which is why he was moved to relief to focus on using his two best pitches. With better fastball locations, Hoffmann could move from middle relief into the later innings.
35+ FV tier
Acquired from New York Yankees in Amed Rosario deal
Beeter was a second-round pick in the 2020 draft and has slowly moved down the starter-to-reliever spectrum to becoming a full-time reliever for the first time in 2025. He’s 26 years old with five career big league appearances under his belt, but Beeter is still in Triple-A for now because of his walk rate: 7.2 per 9 innings — including issuing seven walks in his last 8⅓ innings pitched.
Beeter is still a solid prospect because of his 65-grade slider and above-average fastball that peaks at 99 mph. His fastball command is the variable that, with more progress, could turn him into a late-inning reliever, but Beeter is a higher-variance middle reliever who needs to avoid walks in Triple-A to get his next big league shot.
Acquired from the Tampa Bay Rays in the Nick Fortes deal
Etzel is a long-term left field fit who was also traded at last year’s deadline from Baltimore in the Zach Eflin deal. Etzel is an above-average runner with some feel for stealing bases and fits long term as a potential platoon corner outfielder if things go well. He has a solid feel for drawing walks and pulling/lifting the ball with his solid-average raw power (think 15-20 homers at peak). His contact rates suggest he might be a .230 or .240 hitter, so Miami is hoping it can get a solid role player out of Etzel.
10. Browm Martinez, CF, Washington Nationals
Acquired from New York Yankees in Amed Rosario deal
Martinez signed for a $130,000 bonus last January and was solid last summer in the Dominican Summer League before having a huge repeat season in the league this year — posting an OPS of 1.139 driven by higher contact rates.
There is still a wide range of potential outcomes for Martinez as an 18-year-old playing in the lowest level of the minors, but the key here is he has above-average bat control and pitch selection at the plate, arguably the two most important things to demonstrate at lower levels.
He’s also a solid-average runner who has 34 career stolen bases, and that speed could allow him to stay in center field. There’s some physical projection left given his age, but his power projects to continue to be below average, so sticking in center would be key to his long-term value.
11. Josh Grosz, RHP, Colorado Rockies
Acquired from New York Yankees in Ryan McMahon deal
Grosz is a potential No. 5 starter/swingman type with some feel and deception from his abruptly quick delivery. He throws a 92-95 mph dead-zone fastball with heavy tail that plays around average, an above-average changeup and a fringy slider.
He has a tougher road to being a solid big leaguer if he can’t stick as a starter because most teams prefer a middle reliever to have an above-average breaking ball to get right-handed hitters out.
12. Cameron Foster, RHP, Baltimore Orioles
Acquired from New York Mets in Gregory Soto deal
Foster is a 26-year-old long reliever who sits 93-96 and hits 99 mph from a high slot (it’s on the whole an average big league pitch). He also mixes in an 86-88 mph cutter (a solid-average pitch), an 81-84 mph slurve (an above-average pitch), and a big loopy 75-78 mph curveball (effective as a fourth offering that’s used in certain situations). He’s a solid back-end-of-the-roster-type utility arm who can be used in multiple roles and should debut this year or next. He needs to be added to the 40-man roster after the season to protect from the Rule 5 draft.
