Colson Montgomery, SS, Chicago White Sox

Level: Triple-A
2025 stats: 58 G, .217/.294/.425, 11 HR, 31 RBI, 30 R, 4 SB, 7.9% BB%, 32.9% K%, .286 BABIP, .321 wOBA, 80 wRC+

A former top prospect and first-round pick, Montgomery has endured a fall from grace over the past season and a half. Still, we're not out on him, especially as he continues to show spurts of optimism at just 23 years old in Triple-A.

A seemingly anomalous 2023 has tailspun into a concerning 2024 and 2025, with Montgomery showing major swing-and-miss concerns while struggling to get on base. With that said, he's a dependable defender with a great glove and arm strength. He's a solid shortstop for now and could survive a move to third base. The power speaks for itself as he owns a 4.7 percent home run rate this year.

Last week, Montgomery went 11-for-22 (.500) with two doubles, one triple, and four home runs. He added eight RBI, one walk, and five strikeouts along the way. While the poor K/BB rate is glaring, the steady power output, ability to drive in runs, and increased productivity at the plate should leave fans with some optimism. When he does get the call to the majors, he has the tools to overcome some early adversity.

Connelly Early, SP, Boston Red Sox

Level: Double-A
2025 stats: 12 G, 9 GS, 6-1, 55.2 IP, 1.94 ERA, 2.20 FIP, 13.10 K/9, 3.88 BB/9, 0.16 HR/9, 52.7% GB%, .305 BABIP

Early is a former fifth-round pick out of Virginia, and he's the second Portland Sea Dogs pitcher to appear in this series over the last two weeks. Drafted in 2023, Early has emerged as one of the best pitching prospects within Boston's promising farm system.

Early gets the best results when he can set the tone early in counts with his fastball and slider. Then, he's able to get plenty of whiffs against both left- and right-handed hitters with his changeup. The strikeout rate shows no lack of control, although we'd like to see a slightly lower walk rate at the Double-A level.

Last Sunday, Early went six full innings, allowing zero earned runs, three walks, and seven strikeouts. He earned the win, jumping to 6-1 on the year. He continues to blank opponents, limit loud contact, and rack up strikeouts. Cutting down on walks will be the next big task for the left-hander.

Absolute dominance from Connelly Early on Sunday. 😮‍💨

Colton Ledbetter, OF, Tampa Bay Rays

Level: Double-A
2025 stats: 64 G, .280/.362/.414, 5 HR, 27 RBI, 40 R, 22 SB, 10.9% BB%, 26.1% K%, .373 BABIP, .366 wOBA, 131 wRC+

Ledbetter was the Rays' second-round pick in 2023, and he's in the midst of his third pro season after an impressive run at Mississippi State. The 23-year-old outfielder has impressed in the minors, and he's making a case for a promotion to Triple-A soon.

The hit tool has historically been viewed as Ledbetter's biggest weakness, and while his strikeout rate is still elevated, he's also drawing more walks and delivering excellent contact. He's shown the occasional flash of power, too. Defensively, he's an above-average fielder with good speed and a strong arm. He's seen more time in right field than center this year, but he can certainly handle either.

Last week, Ledbetter went 12-for-23 (.522) with one home run, three doubles, four RBI, five walks, and four strikeouts. He also went 1-for-3 stealing bases. The baserunning results were abnormally poor, but otherwise, he put together a phenomenal week at Double-A. Rays fans should feel optimistic about Ledbetter if his bat can continue to play.

Ended Kimchi Night with a SPLASH!

Robby Snelling, SP, Miami Marlins

Level: Double-A
2025 stats: 13 G, 13 GS, 3-5, 67.1 IP, 3.74 ERA, 2.75 xFIP, 10.29 K/9, 2.81 BB/9, 0.67 HR/9, 51.7% GB%, .318 BABIP

Snelling is a southpaw whom San Diego selected with the 39th pick in the 2022 draft. He was flipped to Miami in last summer's Tanner Scott trade. The 21-year-old went straight from prep baseball to the minor leagues, inking a $3 million contract along the way.

Snelling throws a mid-90s fastball with ride, and it's merely an average offering that can be used early or behind in counts. He gets much better results from his changeup and slider, both of which can induce plenty of swings and misses.

Last Tuesday, Snelling went seven complete innings, allowing zero runs, zero walks, and just three hits. He struck out seven batters along the way, strengthening his impressive strikeout rate. Miami does not need to rush Snelling, but he's certainly making his impression in the minors. A promotion to Triple-A is likely in his future.

John Peck, SS/3B, Detroit Tigers

Level: High-A
2025 stats: 64 G, .308/.368/.442, 7 HR, 44 RBI, 52 R, 12 SB, 7.7% BB%, 28.4% K%, .424 BABIP, .381 wOBA, 132 wRC+

Peck is the lowest-profile name on this list, but he bears mentioning after a spectacular month of June. The 22-year-old was drafted by Detroit in the seventh round of the 2022 draft after a solid collegiate career at Pepperdine. He plays on the left side of the infield, with the majority of his reps coming at shortstop.

The modest power we've seen Peck flash from time to time is back on display this year. He can launch the ball to all parts of the field, delivering quality contact. His K/BB ratio isn't ideal and should be the primary area of focus as he works with Detroit's development department. He runs pretty well and plays solid defense, which should allow him to stick at shortstop long-term.

Last week, Peck went 14-for-29 (.483) with one home run, two doubles, seven RBI, one walk, and five strikeouts. He also stole two bases. Keep Peck on your radar as he climbs through the minors. Even if the power doesn't quite pan out, he should remain a steady producer both in terms of hitting and defense.

Just a single for John Peck, but it’s an excuse to talk about his terrific month of June. He’s now 32-for-89 (.360) with 7 doubles, a triple, and 3 homers in 20 games. Also has 5 steals, but the plate discipline needs work (3BB, 22K). pic.twitter.com/hSUaVa4lKD
