Top Second Base (2B) Fantasy Baseball Prospects for 2025

Zach's top fantasy baseball prospects sleepers at second base for 2025 redraft leagues. His top breakout rookies and call-ups at second base (2B) for 2025.

Second base can be tricky for fantasy baseball. It's not typically a "glamor spot" where the fastest, most athletic, or even most powerful players end up. However, at the MLB level, a few elite players offer strong combinations of power and speed, making them even more valuable because they produce elite numbers from a position lacking depth.

One strategy for attacking second base is to try to grab a young prospect who is ready to make an impact this season. Several of the top options offer good blends of multiple skill sets and could be big producers once they reach the majors. There are question marks about when they'll arrive in the majors, though.

If you're in a redraft league, these five options are close enough to make an impact and are worth watching. You can add them late in the draft or snag them when they are called up mid-season. At some point this season, it looks like there will be some exciting young players at this spot in 2025, even if most of these options start the year in the minors. Here are my top five prospects to watch at 2B in redraft leagues.

Kristian Campbell, Boston Red Sox

Campbell is a huge part of Boston's young core of prospects, which makes it one of the top farm systems in the MLB. Before the Alex Bregman signing, there was talk of giving Campbell the everyday 2B job and letting him play every day, but with Bregman in the mix, his path to an everyday role is a little more murky.

Last year, Campbell skyrocketed through the minors and went from a fourth-round pick that wasn't on anyone's top lists to the Baseball America Minor League Player of the Year and one of the top prospects in the game. He started the year at High-A in Greenville and finished in Triple-A with the Worcester Red Sox. In his 115 games, he hit a combined .330 with 20 home runs, 24 stolen bases, and a .447 wOBA.

He struggled early in Spring Training but started to have better at-bats as Spring Training went along. He also made some noise at the Spring Breakout showcase against the Rays.

Campbell could bring a very productive combination of power and speed to 2B this season and move around enough to be a valuable utility asset for your fantasy team. He has played the outfield in Spring Training, and if he mashes in Triple-A, he could be in the MLB quickly.

Christian Moore, Los Angeles Angels

Moore was the No. 8 overall pick in the MLB Draft just last year, but he's already nearing his arrival in the MLB. The Angels have pushed other prospects like Nolan Schanuel and Zach Neto quickly to the majors, and Moore may be next in line. He was already expected to compete for playing time at 2B before Anthony Rendon’s hip injury, which stretched the depth chart even thinner.

Moore looked very good in 25 games across Single-A and Double-A last season. Moore hit .347 (35-for-101) with six doubles, six homers, and a .449 wOBA. While there's obviously not much sample size there, he could have gotten a September call-up if not for a late-season injury.

This Spring Training, Moore went 9-for-38 (.237) with six walks, a stolen base, and a triple.

He's right on the borderline of making the roster or starting in Triple-A. Either way, once he arrives, he'll have good speed and average upside. He doesn't seem quite as ready as Campbell, but it helps that he doesn't have much blocking his way in the Angels' infield.

Orelvis Martinez, Toronto Blue Jays

Martinez has a much longer track record than either Campbell or Moore and has worked his way up through the Blue Jays system since 2019 when he signed as a 17-year-old. He has 28 home runs in 2023 with a .243 batting average and .363 wOBA in 125 games and hit a solid .267 in 17 homers and a .375 wOBA in Triple-A last year.

He was ranked as the No. 89 prospect in baseball by MLB Pipeline but only played one game in the MLB before being hit with an 80-game suspension last year for PED use. He did not return to the field after that suspension last year.

This Spring Training, though, Martinez has been battling for a roster spot and looking to earn playing time in a crowded infield. With newly-acquired Andres Gimenez likely locked in at 2B, Martinez could play 3B if he can get time from Ernie Clement, who is a great fielder but not as consistent at the plate.

He started spring strong, going 8-for-24 (.333) with a home run, three RBI, and a pair of walks.

This is a statement spring for Orelvis Martinez and he showed out today with his first HR of the spring!

Martinez is right on the edge of the roster, like both Moore and Campbell. If he gets playing time, he does have power potential, although his speed doesn't give him quite as diverse potential as Campbell or Moore. He's worth watching and could be worth grabbing if he starts the season with the Jays or is called up early in the season.

Luke Keaschall, Minnesota Twins

Keaschall is another 2B prospect on the rise, but he isn't quite as close to the MLB as the options listed above. Keaschall was sent to minor league camp and will likely start the season at Double-A, although the Royce Lewis injury could shake up the organization's infield depth.

The Twins drafted Keaschall in the second round in 2023, and he reached Double-A for the first time last season. In 102 games last year, he hit a solid .303 with 15 homers and 23 stolen bases while posting a very solid .416 wOBA. He has excellent plate discipline, earning 62 walks and only striking out 80 times. Those numbers are even more impressive when you remember he was playing through an elbow injury that ultimately required Tommy John surgery.

Keaschall's defense is still a work in progress, but he showed promise at the plate this spring with a .238 batting average and this home run before being reassigned.

Like many of the Twins' prospects, Keaschall has had injury issues, but if he continues to develop, he could arrive in Minnesota by the middle of the season.

Travis Bazzana, Cleveland Guardians

Bazzana could end up as the best prospect on this list eventually, but he also has the longest way to go before being ready to contribute in redraft leagues. He was the No. 1 pick in the 2024 MLB Draft out of Oregon State and was touted as one of the most MLB-ready bats available in the draft for a while.

He looked ready to deliver on that promise in his first taste of the pros in High-A last season. He hit .238 with seven doubles, three homers, five home runs, and a .365 wOBA.

In Spring Training, he went just 2-for-12 but both hits went for extra bases with a double and a home run.

The Guardians are planning on him reaching the MLB quickly. The team traded Andres Gimenez to the Blue Jays to clear the way for him and have some "bridge" options to get to him. They've had nothing but great things to say about the 22-year-old lefty's work ethic and how quickly he's already growing, using all the resources the team has available for him.

This season will be fascinating to watch how quickly he can rise through the system. In redraft leagues, you probably can't carry him until his midseason arrival, but if he catches on in the minors and gets the call-up, he'll be a great waiver wire option since the team views him as a cornerstone of their franchise going forward.
