Top 10 Fantasy Baseball Prospect Rankings: Second Basemen

These prospect rankings are based on fantasy baseball value, not real-life value. Considering such, hitters generally weigh a bit heavier for me due to the injury risk and higher volatility of prospect pitchers. Proximity to the Majors is also prominent in the equation, though these prospect fantasy baseball rankings are focused on long-term/dynasty outlooks. Think of these rankings as more of a five-year plan.

Rather than getting into writing mini-bios on all prospects, I’ve decided to keep my rankings simple by providing the 2024 and 2025 stats of each player across all levels, plus a player comp, a small blurb on their prime skills for fantasy and an explanation of my ranking.

I’ve also included updated fScores for any players I expect to debut in 2025 (some are updated from May, while others still feature preseason fScores), which highlights what my fScore projections believe the player is capable of at the pro level for immediate impact.

I know most people don’t care to read 250-500 words on each player, so using both box score scouting and film review, I have provided comps for each prospect. For fun, note that comps may be based on mechanics, body type, pitching arsenal or similar skills & box score style and how I think each prospect will perform once in the Majors over the next five seasons or so.

All-in-all, rankings paired with statistical info and a player comp will hit the sweet spot for the broadest category of people reading these prospect fantasy baseball rankings (or listening/watching the Fantasy Aceball podcast).

NOTE: Rookie status is determined by 130 at-bats or 50 innings pitched at the Major League level.

Top 10 Fantasy Baseball Prospect Rankings: Second Basemen

1. Luke Keaschall (2B – MIN)

• 2024 A+/AA: .303/.420/.483 | 13.4 BB% / 17.2 K% | 37 XBH, 15 HR, 23 SB (102 games)
• 2025 AAA: .261/.379/.348 | 15.5 BB%, 19 K% | 2 XBH, 1 HR, 4 SB (14 games)
• 2025 MLB (as of 6/23/25): .368/.538/.526 | 19.2 BB%, 7.8 K% | 3 XBH, 0 HR, 5 SB (7 games)
• ETA: Debuted
• fScores: 108 fContact, 116 fDiscipline, 95 fPower, 156 fSpeed
• Age: 22
• Comp: Righty Brendan Donovan with Matt McLain tools
• Prime Skills: Luke Keaschall has great bat speed with killer exit velocities. The home run power should be greater and will increase as he ages. He was having a strong season with consistent weekly production. He has a 65 grade hit tool, 60 grade plate skills and 45/50 power with 55/60 speed. I expect a lot of doubles out of him, but maybe only 15-ish homers.
• Ranking Explanation: Keaschall recovered from Tommy John surgery much quicker than expected, was promoted to the Majors and was electric in his small sample size before his broken arm after getting hit by a pitch. Don’t expect him back until after the All-Star break. Keaschall is running 93% Z-Contact rates in the Minors and Majors this year and increased his aggressiveness to a 70% Z-swing% in the Majors, which led to the killer start pre-injury. He’s a stud and it’s a shame he got injured.
• Top 150 Ranking: 16

2. JJ Wetherholt (2B, SS – STL)

• 2024 College: .331/.472/.589 | 16 XBH, 8 HR, 6 SB (36 games)
• 2024 A: .295/.405/.400 | 12.7 BB%, 11.9 K% | 7 XBH, 2 HR, 2 SB (29 games)
• 2025 AA (as of 6/23/25): .321/.443/.467 | 16.7 BB%, 13.2 K% | 18 XBH, 4 HR, 12 SB
• Age: 22
• ETA: Early 2026
• fScores: 102 fContact, 128 fDiscipline, 86 fPower, 136 fSpeed
• Comp: Corbin Carroll/Marcus Semien mash-up
• Prime Skills: JJ Wetherholt hits the crap out of the ball for a smaller guy, is athletic and has a great eye at the plate. He has a quick and easy swing with great bat control that will lead to an early career high doubles profile that later translates into more power as he gets closer to his peak. Wetherholt had an average exit velocity of 91.8 last season to go along with an aggressively effective approach in the zone with a 73.4% Z-Swing% and only a 14.1% chase rate to pair with an 86% contact rate this season in AA. He has no splits concerns as a lefty.
• Ranking Explanation: He’s going to put up 40 doubles a season with a high batting average when he first breaks into the Majors. Busch Stadium is terrible for lefty power (as we have seen with many Cardinals lefties like Lars Nootbaar), but he should still get to 15-20 homers since he has a ton of opposite-field power. He will be a much better points league player than roto player for fantasy purposes because of where he plays. He has been playing some second base with no playing time at third. He’s a good athlete and looked smooth defensively, so this could change depending on how the Cardinals change their team in the coming months. Keaschall gets the slight edge based on proximity, a better stadium and higher stolen base potential.
• Top 150 Ranking: 18

3. Kevin McGonigle (2B, SS – DET)

• 2024 A/A+: .309/.401/.452 | 14 BB%, 8.5 K% | 25 XBH, 5 HR, 22 SB (74 games)
• 2025 Season (as of 6/23/25): .371/.460/.664 | 24 XBH, 5 HR, 1 SB
• Age: 20
• ETA: Late 2026
• fScores: N/A
• Comp: Chase Utley wannabe (with less power and more speed) plus bit of a Steven Kwan profile in the middle infield
• Prime Skills: Kevin McGonigle has an insane hit tool, running only an 83% contact rate in the small sample size this year, he also has a 91% Z-Contact% on the short season. It’s a small sample size, but the average exit velocity is up at 93.8, while the 90th is still below 104 and the max is under 108. Even with a large focus this offseason on building power, he may just be a plus-doubles guy with speed.
• Ranking Explanation: McGonigle had missed most of the season once my rankings came out a few weeks ago, with an ankle sprain, but he’s been insane since coming back and deserves a major rankings boost. He’s been a great contact hitter (near 95% Z-Contact% in 2024), avoids strikeouts (only a 22% chase rate) and steals bags. The exit velocities have still been slightly below average despite increased power, and the speed has been disappointingly down this year, but the hit tool is top-level. Wetherholt is in the same bucket, but has a higher power/speed potential than McGonigle.
• Top 150 Ranking: 36

4. Travis Bazzana (2B – CLE)

• 2024 College: .407/.568/.911 | 48 XBH, 28 HR, 16 SB
• 2024 A+: .238/.369/.396 | 13.9 BB%, 25.4 K% | 10 XBH, 3 HR, 5 SB (27 games)
• 2025 AA (as of 6/23/25): .252/.362/.433 | 12.8 BB%, 26.2 K% | 12 XBH, 4 HR, 8 SB
• Age: 22
• ETA: Early 2026
• fScores: 96 fContact, 122 fDiscipline, 90 fPower, 155 fSpeed
• Comp: Daniel Murphy with more athleticism and quickness
• Prime Skills: Travis Bazzana has the killer Oregon State hit tool and has professional experience already with wood bats, playing in Australia as a pro as a teenager. He has power and speed, but to what degree both will show up as a pro is the big question, as the game power just appeared in 2024 and is relatively a newer tool. We haven’t seen it come around yet in the Minors, and this injury will halt his development.
• Ranking Explanation: Bazzana was tagged with an oblique injury that will put him on the shelf until August, which dings him a bit as he definitely won’t debut this season, and it will push his development behind some of the others. Bazzana may have more power and speed potential than Wetherholt and will play in a slightly better stadium, but Wetherholt has a better hit tool and plate approach.
• Top 150 Ranking: 26

5. Jett Williams (2B, SS, OF – NYM)

• 2023 A/A+/AA: .263/.425/.451 | 43 XBH, 13 HR, 45 SB
• 2024 A/AA/AAA: .215/.358/.298 | 14.9 BB%, 23.6 K% | 9 XBH, 0 HR, 5 SB (33 games)
• 2025 AA (as of 6/23/25): .298/.407/.514 | 14.7 BB%, 20.5 K% | 30 XBH, 6 HR, 21 SB
• Age: 21
• ETA: Late 2025 (September)
• fScores (pre-season): 86 fContact, 146 fDiscipline, 78 fPower, 148 fSpeed
• Comp: Jose Altuve build with Bryson Stott-like production
• Prime Skills: Jett Williams has good plate skills and speed, but his contact tool is still developing. It should ultimately be a good tool for Williams, as he has gotten the hit tool back to his pre-injury 2023 levels with an 80.1% contact rate. He has non-zero power. His quick swing leads to a surprising number of extra-base hits.
• Ranking Explanation: Williams was a top-30 prospect before his injury last year. He returned to the Arizona Fall League with two homers and seven steals after a short season. Williams projects as a future 10-15 homer and 30-40 steal player with an insanely good plate approach if he can increase the aggressiveness in his approach, as that’s what seems to be holding down the average. The 170 wRC+ this season is fantastic. He’s still young for the AA level and could debut this season. His fScores would be much improved from last year, as they were based on an injured Williams. He’s a top-flight prospect. Second base is stacked right now, prospect-wise.
• Top 150 Ranking: 37

6. Michael Arroyo (2B, SS – SEA)

• 2024 A/A+: .285/.400/.509 | 12.3 BB%, 23 K% | 56 XBH, 23 HR, 18 SB
• 2025 A+ (as of 6/23/25): .269/.422/.512 | 12.7 BB%, 21.2 K% | 29 XBH, 15 HR, 3 SB
• Age: 20
• ETA: Mid 2026
• fScores: N/A
• Comp: More athletic Ronnie Belliard build with a Jorge Polanco-ish to Matt McLain-lite profile.
• Prime Skills: Michael Arroyo is a short, swinging, stocky athlete with quick hands and a ton of power in his fire hydrant frame. He has some speed. He has a good plate approach and above-average contact tool, which led to the 2024 breakout.
• Ranking Explanation: Arroyo’s contact rates are down a bit this year, resulting in a bit less damage, but he’s still putting up a 136 wRC+ — slightly below the average age to level by enough to provide maybe a 10-point boost to his wRC+. The speed has not been a part of his game this season, which I kind of expected based on his frame, making him more of a points league play longer term rather than an option in categories leagues. Looks like a .255/.370/.430 player who will pop 20-25 bombs with only a few steals as a Major League second baseman. Arroyo was finally promoted to AA with Lazaro Montes the other day and likely has the highest power ceiling (right there with Wetherholt) out of all the second base prospects thus far in the rankings. The others have elite hit tools or, in the case of Jett Williams, an elite plate approach with a solid hit tool teamed with plus-speed.
• Top 150 Ranking: 51

7. Christian Moore (2B – LAA)

• 2024 College: .375/.451/.797 | 55 XBH, 34 HR, 5 SB
• 2024 A/AA: .347/.400/.584 | 8.2 BB%, 26.4 K% | 12 XBH, 6 HR, 2 SB (25 games)
• 2025 AA/AAA: .279/.374/.422 | 13 BB%, 27.3 K% | 18 XBH, 5 HR, 8 SB
• 2025 MLB (as of 6/23/25): .167/.194/.333 | 3.1 BB%, 34.4 K% | 2 XBH, 1 HR, 0 SB
• Age: 22
• ETA: Late 2025
• fScores: 95 fContact, 78 fDiscipline, 96 fPower, 109 fSpeed
• Comp: Connor Norby profile with some Alex Bregman mechanics
• Prime Skills: Christian Moore is a big second baseman with a sweet righty swing through the zone with some easy power for a middle infielder. He has killer middle infield power with a great field of hit and very good plate skills. He has some strikeout issues and the hit tool is below average (68.2% contact rate), but the power should play up at second base even with lower-than-expected exit velocities this season (87.4 average exit velocity; 108.7 max exit velocity).
• Ranking Explanation: Moore started hot last season in the Minors, and is a gamer with a lovely swing. He’s already been promoted to the Majors, but hasn’t done much outside of a homer and a triple in 10 games. He’s a tier off from the above prospects (two tiers off in some cases). He has some Arroyo-esque power potential, but he doesn’t have as good of a hit tool or plate skills.
• Top 150 Ranking: 63

8. Cole Young (SS – SEA)

• 2024 AA: .271/.369/.390 | 12.1 BB%, 15.8 K% | 36 XBH, 9 HR, 23 SB
• 2025 AAA: .277/.392/.461 | 12.7 BB%, 11.4 K% | 23 XBH, 5 HR, 4 SB
• 2025 MLB (as of 6/23/25): .236/.271/.291 | 5 BB%, 26.7 K% | 3 XBH, 0 HR, 0 SB
• Age: 21
• ETA: Late 2025
• fScores: 104 fContact, 126 fDiscipline, 81 fPower, 106 fSpeed
• Comp: Jackson Holliday-lite
• Prime Skills: Cole Young has a plus-hit tool (83.3% contact rate and 90.2% Z-Contact%) to go along with great plate skills, especially for a player his age. He is always playing a couple of years ahead in age-to-level. The speed is good, but not great. He has quick hands and is starting to hit the ball in the air more as he moves up each level.
• Ranking Explanation: I like Young as a real-life player rather than a fantasy asset, especially now that the power is improving from the lower rungs. He’s going to be a winner in points leagues with a 122 wRC+ in AAA, a 30-40-point bump for the age-to-level is fair, and the power is coming along (89.9 average exit velocity and 109.2 max exit velocity this year). He’s had a rough transition to the Majors after his promotion, as his contact rate is below the average jumper from the Pacific Coast League to the Majors. I think he will adjust, but it might not be for a few months, if not until next year.
• Top 150 Ranking: 74

9. Aroon Escobar (2B, 3B – PHI)

• 2024 CPX: .338/.495/.481 | 20.2 BB%, 9.6 K% | 5 XBH, 3 HR, 9 SB
• 2025 A (as of 6/23/25): .295/.387/.466 | 11.2 BB%, 17.5 K% | 20 XBH, 10 HR, 6 SB
• Age: 20
• ETA: 2027
• fScores: N/A
• Comp: Jean Segura
• Prime Skills: Aroon Esocbar has a fire hydrant build at 5-foot-10 and 180 pounds. Has simple swing mechanics and a naturally laid-back load that leads to a solid hit tool (82.4% contact rate last year; 77.8% this year) with a plus-plate approach and emerging power to pair with above-average speed. I admittedly wasn’t the biggest fan of his profile this offseason due to the lack of extra-base hits, but the power has appeared this year with a 105.9 90th percentile exit velocity and 28% line drive rate, which has brought about the extra-base hits in 2025.
• Ranking Explanation: Escobar is likely ready for High-A, which might be more age-appropriate for someone ranked this high. He’s been killing it in the sweet spot department this year and is highly aggressive in-zone, equally mashing against both righties and lefties. There’s a lot to like here, but he is only in Low-A, and there’s a lot of development left for him.
• Top 150 Ranking: 80

10. Termarr Johnson (2B – PIT)

• 2024 A+/AA: .237/.366/.386 | 15.6 BB%, 21.3 K% | 39 XBH, 15 HR, 22 SB
• 2025 AA (as of 6/23/25): .249/.336/.389 | 11.5 BB%, 17.6 K% | 16 XBH, 7 HR, 10 SB
• Age: 20
• ETA: Mid 2026
• fScores: N/A
• Comp: Short Jason Kipnis; might have some Hunter Dozier-esque or Brandon Phillips-esque seasons
• Prime Skills: Termarr Johns has amazing plate skills for his age and the hit tool is a tad underrated as he has a 73.9% contact rate, which is reasonable considering the upper-tier plate skills and the solid home run power. It would be nice to see some gap power come around, as he doesn’t hit as many doubles as you would like.
• Ranking Explanation: The power has been surprisingly above average, but that may be at the expense of the hit tool, which was supposed to be his top tool when he was drafted. Johnson needs to develop more of a doubles profile to make it. He’s underrated as a prospect right now, as there is some prospect fatigue, but a 112 wRC+ as a barely 21-year-old in AA is nothing to be ashamed of. Age-to-level, he deserves a 40-point assumed bump, but he hasn’t been great since my rankings update. Demetrio Crisantes would have been ahead of him if healthy.
