Top 10 Second Base Prospect Rankings for Fantasy Baseball (2025)

For the most part, the second base position has been one of the weaker positions on the field offensively. After several seasons with this position on the rise, we saw second base fall off as a whole last season due to injuries and some of the aging top options at the position fall off.

But luckily, the current crop of second base prospects is pretty exciting with two Top 10 overall prospects and plenty of intriguing targets for dynasty leagues. And per usual, we'll see some shortstops slide over here eventually as well, as not everyone can stick at shortstop. Even if they want to.

Second Base Prospect Rankings for Fantasy Baseball

Age and highest level in parenthesis

1. Kristian Campbell, BOS (22/AAA)

The astronomical rise of Kristian Campbell in 2024 was one for the ages. He went from an intriguing fourth-round pick in 2023 to one of the best prospects in baseball and inside my Top 5 overall. In 115 games across three levels, Campbell slashed .330/.439/.558 with 32 doubles, 20 home runs, and 24 steals.

There were some questions about Campbell's power entering the season, but he silenced any doubts by posting above-average quality of contact metrics, including a 46.2% hard-hit rate in Triple-A to pair with an 81.8% contact rate and 90.8% zone contact rate.

All the ingredients are there for Campbell to be a high-impact fantasy bat. He makes plenty of contact, hits for power, is an above-average or better runner, and has a solid plate approach. All of that from the second base position is incredibly exciting.

2. Travis Bazzana, CLE (22/A+)

Everywhere Travis Bazzana has played, he's hit and hit well. After three standout years at Oregon State along with a great showing in the Cape Cod League back in 2023, Bazzana was the first overall pick in the 2024 draft and was assigned to Hi-A Lake County for the final several weeks of the minor league season. In 27 games, Bazzana only hit .238, but with three home runs, five steals, 17 walks, and a .369 OBP.

Bazzana was considered to be one of the best pure hitters in the entire 2024 draft class and should post higher AVGs and OBPs annually. But he's far from a contact-only hitter thanks to above-average power and speed, which could have him pushing 20/20 annually as well.

2 weeks ago I met with Travis Bazzana, the #1 overall pick in the 2024 MLB draft.

We had a conversation I wish all baseball players could have heard.

Here's the #1 takeaway (that made him the first overall pick): pic.twitter.com/IUqehJelvJ

This is a well-rounded offensive profile and one that could push Bazzana to elite ranks at the second base position for fantasy purposes. We could see him up with Cleveland by the end of 2025 as well.

3. Kevin McGonigle, DET (20/A+)

Out of all the hitters from the 2023 draft class, you could make a case that Kevin McGonigle is the best pure hitter overall. After hitting .315 with a .452 OBP in 21 games after the draft in 2023, McGonigle slashed .309/.401/.452 in 74 games last season along with 25 extra-base hits, five home runs, 22 steals (only caught twice), and more walks (46) than strikeouts (28).

I'm not one to hand out 70-grade hit tools often, but McGonigle fits the mold thanks to his near-90% contact rate and phenomenal approach at the plate. He's also an average or better runner with a high efficiency stealing bags and there's sneaky power here (89.5 mph AVG EV) with more waiting to be unlocked.

At his peak, McGonigle doesn't project as a massive power/speed threat, but he could be a 20/15 type with a high AVG and OBP. You'll definitely take that outcome.

4. Michael Arroyo, SEA (20/A+)

Without question, Michael Arroyo is one of the more underrated prospects in baseball. No single tool stands out, but Arroyo is an above-average hitter who can work the count and provide at least average power and speed. That power is still trending up too, so don't be surprised if Arroyo is an above-average power bat when he reaches the majors.

In 120 games this past season between Lo-A and Hi-A, Arroyo combined for 26 doubles, 23 home runs, 18 steals, and a .285/.400/.509 slash line in 120 games. This was the third straight season Arroyo had an OBP of .400 or higher and the first where he really started tapping into his raw power. This is a Top 50 fantasy prospect in my eyes and one who doesn't often get ranked that highly.

5. Luke Keaschall, MIN (22/AA)

Without a ton of fanfare, Luke Keaschall quietly had a productive season in 2024. In 102 games between Hi-A and Double-A, Keaschall slashed .303/.420/.483 with 21 doubles, 15 home runs, and 23 steals. Keaschall is a plus hitter who posted a contact rate above 80% along with a 13.4% walk rate and a 17.2% strikeout rate in 2024. He's also an above-average runner.

Luke Keaschall stays red hot with his third straight multi-hit game while also clubbing his second leadoff HR in three games 🥵

He went 3-4 with a HR (100.1 mph)

Over his last 30 games in Double-A, he is slashing .339/.447/.513 (.960 OPS), which is a 168 wRC+📈#MNTwins pic.twitter.com/H1hAbW8v4x

— Twins Player Development (@TwinsPlayerDev) July 12, 2024

The power lags a bit, but there's enough power in the tank to be a 15-homer bat long-term to add to a higher AVG/OBP and possibly 20 steals as well. It might not be a sexy profile with below-average power, but this is a high-floor profile with sneaky offensive potential and one we could see with Minnesota during the 2025 season.

6. Ronny Mauricio, NYM (23/MLB)

Remember him? After back-to-back 20/20 seasons in 2022 and 2023, along with a 26-game cup of coffee with the Mets, Ronny Mauricio missed the entire 2024 season after tearing his ACL in winter ball. All indications are that he should be 100% ready for spring training and could make a push for a starting spot with the Mets out of camp.

Mauricio's aggressive nature will always limit him, especially in the OBP department, but the upside is a 20/20 player from the second base position who can hopefully hit at least .250. While there's elevated risk here, Mauricio is a solid dynasty buy this offseason.

7. Christian Moore, LAA (22/AA)

After a standout final collegiate season at Tennessee, Christian Moore was selected 8th overall by the Angels and immediately was put into their MLB lineup. I'm obviously kidding, but Moore did find himself in Double-A after just two Single-A games and immediately made his presence felt in the Southern League with five home runs in his first six games at the level.

However, after a torrid first nine games where he had 20 hits and six home runs, Moore slashed just .231/.296/.292 the rest of the way with 24 strikeouts in six games.

It's hard to read into either of those two small sample sizes though. I'm not sure Moore ever provides more than 5-10 steals annually, but he's an above-average or better power bat with 25-30 homer upside from the second base position and can draw plenty of walks. If he can make enough contact and keep the strikeout rate in check, Moore could develop into a standout fantasy second baseman.

8. Adael Amador, COL (21/MLB)

It was a weird season for Adael Amador. After being limited to 69 games in 2023, Amador played in 100 games this past season with 14 home runs and 35 steals, but his AVG and OBP dropped from .302 and .392 to .230 and .343 respectively. That OBP is still solid, but what happened to the AVG?

Amador was still making contact at a near 80% clip, but it appears he was trying to tap into more power as his groundball rate dropped and the pull rate rose to over 50% in 2024. That didn't exactly work, as most of his home runs came in one series here in Portland, Maine.

Yes, Amador has some power, but he's more valuable when he's hitting for a high AVG and getting OBP. I'd rather have that with around 15 home runs and steals than the version of Amador we saw in 2024.

9. Yoeilin Cespedes, BOS (19/CPX)

After breaking out in the DSL back in 2023, Yoeilin Cespedes was having another impressive season at the Complex Level before a broken hand ended his season early. In 25 games before the injury, Cespedes slashed .319/.400/.615 with 10 doubles and five home runs.

While he's not considered much of a runner, Cespedes packs a punch at the plate with quick hands and a solid frame creating above-average power for his age. He's also shown an advanced feel for the zone for his age which hopefully translates to full-season ball in 2025. There's a chance Cespedes could be Boston's next exciting infield prospect and rise up rankings considerably in 2025 and 2026.

10. James Triantos, CHC (21/AAA)

All Triantos has done since entering the minors back in 2021 is hit, hit, and hit some more. After a .300 AVG in 2024, Triantos is now hitting .289 for his minor league career over 336 games and has never hit below .272 at any level (said low mark came back in 2022 in Lo-A). Over the last two seasons, he's been above .285 at every level with a combined 11% strikeout rate.

Triantos does two things incredibly well: make contact and steal bases. He posted a contact rate of around 85% in 2024 while stealing 47 bags in 50 attempts. I'm not sure he's ever more than a 10-12 homer bat, but that should come with a high AVG and potentially 30-35 steals annually.
