10 Hottest MLB Prospects Taking Over the League
The minor leagues are bursting with talent, and a handful of players are pushing hard on the door to the big leagues. These prospects are heating up with loud numbers, tools that pop, and timing that lines up with major league needs. Here’s a look at 15 players who are doing the most to force the next call-up.
1. Roman Anthony

Hard contact has become routine for Boston’s top outfield prospect. Through 56 games in 2025 at Triple-A Worcester, Roman Anthony is slashing .290/.421/.495 with 10 home runs, a 21.1% strikeout rate, and an elite 18.8% walk rate. His average exit velocity sits around 92.5 mph, with multiple batted balls exceeding 110 mph. Anthony also continues to handle both fastballs and offspeed pitches with maturity.
2. Samuel Basallo

Power has never been a question for Samuel Basallo, who launched 20 home runs in 2023 and already has 11 in 2025 through 50 games at Double-A Bowie. What’s made him more dangerous lately is how much better he’s controlling at-bats—his strikeout rate has dropped to 18.9%, and his walk rate has climbed to 10.6%, which shows real maturity at the plate.
3. Brady House

Pitchers haven’t found a consistent way to beat him lately—Brady House is batting .312 with a .538 slugging percentage over his last 25 games at Double-A Harrisburg, with most of his damage coming against fastballs up in the zone. Defensively, House’s arm strength—graded 65 on the scouting scale—and improved footwork at third base have held up under pressure, especially on backhand plays and throws across the diamond.
4. Colby Thomas

Over his last eight games, Thomas has been hitting .382 with three homers and a 1.227 OPS. The strikeouts are still there, but so is improved zone contact. With Oakland fading fast in the standings, there’s no reason to delay giving Thomas a shot.
5. Chase DeLauter

The stat line might not jump out–180 average and just three homers–but the contact quality does. DeLauter’s average exit velocity sits near 95 mph, and his 57.9% hard-hit rate suggests he’s due for better results. If luck starts cooperating, he could be the bat Cleveland’s underwhelming outfield needs.
6. Bryce Eldridge

Bryce has been meeting that challenge with a more refined approach. His long frame doesn’t stop him from generating quick, compact swings. San Francisco just moved on from a veteran first baseman, and Eldridge brings much-needed upside to a lineup lacking pop.
7. Jordan Lawlar

Adjustments at the plate have paid off—Lawlar has shortened his load, timed breaking pitches more effectively, and shown better plate coverage against right-handed arms. His defense at short remains consistent. After two quiet MLB stints, Lawlar looks ready for another shot with far more polish.
8. CJ Kayfus

Kayfus isn’t too flashy, but his contact skills are among the sharpest in Cleveland’s pipeline. He’s shown he can hit left-handed pitching and is making consistent zone contact while adding corner outfield to his résumé. He could plug into several roster spots.
9. Jonathon Long

Long handled both velocity and breaking stuff, with consistent pull-side loft and clean two-strike swings. The Cubs haven’t given him a clear runway yet, but his contact quality and plate discipline are better than a few of the guys ahead of him on the depth chart.
10. Deyvison De Los Santos

De Los Santos has cut down on his swing length, and it’s showing in his results. He’s still generating top-end exit velocities, but his improved two-strike approach has helped him avoid the extended slumps that plagued earlier seasons.
11. Aidan Miller

Miller’s quick hands and compact swing make him tough to beat inside, as shown by his .486 slugging percentage on pitches in the inner third during his High-A stint in 2025. He doesn’t chase much and has adjusted well to pitchers relying on spin. He’s still developing physically, but Philadelphia sees a clear future role—and it may arrive faster than expected.
12. Walker Jenkins

Jenkins’ bat control is what’s separating him in Minnesota’s system. Through 38 games at High-A Cedar Rapids, he’s batting .305 with a .374 OBP and showing consistent contact against both velocity and spin. Defensively, he’s still limited to right field but has shown improved route efficiency and reaction time in recent tracking data.
13. George Klassen

He’s reached 100 mph multiple times this season and has improved his control enough to remain a starter. The Angels tend to push pitching prospects aggressively, and with Klassen already in the upper minors, his debut could come by late summer.
14. Coby Mayo

Triple-A pitchers haven’t found a way to keep the ball in the yard when Mayo gets extended. He’s crushed outer-half pitches and shown better bat control in two-strike counts. Third base remains a question defensively, but Baltimore has DH at-bats to spare.
15. Carson Williams

Williams remains one of the most polished defenders in Tampa Bay’s system, with a .978 fielding percentage over 56 games at shortstop in Triple-A Durham. His power stroke has come alive over the past few weeks. He’s cut down on chasing breaking balls in the dirt and started turning on fastballs inside—two things that slowed him down earlier this year.
