2025 Top Second Basemen for Dynasty Fantasy Baseball

We won’t get too deep into the analysis because the reality is you know most everything you need to know to about the Major Leaguers at this point. Prospects are where the true writeups and reports are needed.

Tier 1: Mookie Betts

Betts is the clear-cut top at the second base position. Sure, he has a bit of a down year in 2024, hitting just 19 home runs and stealing 16 bases, but he also slashed .289/.372/.491 while having eligibility at second base, shortstop, and outfield.

Now 32 years old, some have asked if Betts is in decline, and I just don’t think so. He still put up strong underlying data. The average exit velocity was around his career average at 90 mph. His sweet spot rate was one of the best in baseball at 39.3 percent, but somehow, Betts had the worst barrel rate of his career since 2017.

The contact skills and approach are still there. Betts should be a five-tool player for several more years.

Tier 2: Ketel Marte, Ozzie Albies

Marte had a career-best season in 2024, mashing 36 home runs while slashing .292/.372/.560. Nearly every quality of contact metric was in the 90th percentile or better for MLB hitters. His average exit velocity of 94 mph was one of the best marks in baseball.

He has a well-rounded skillset given his solid contact and chase rates, plus Marte can steal bases. He probably won’t hit 36 home runs against, but 30 with 5-8 stolen bases will play, especially when you get a solid batting average and OBP from him.

There is significant name value with Albies, and rightfully so. He has put together some great seasons, including 2023 when he hit 33 home runs and slashed .280/.336/.513. There is an argument that Albies was a bit lucky that season, as he hit .318 against breaking balls with a .251 xBA. He also mashed fastballs and had 22 home runs against them.

Albies will never light up his Baseball Savant page, and that is okay. He has lived mainly on lower exit velocities but has perfected pulling the ball to the foul poles for home runs. The batted ball profile shifted slightly in 2024, and Albies hit more pop-ups and ground balls. His barrel rate dropped two percentage points in the process.

The lower average exit velocity was previously mentioned, but Albies 90th percentile was 101 mph in 2024, an incredibly low mark for an MLB veteran. Yes, he pulled 46 percent of his fly balls but had just a 93 mph average exit velocity on that demographic of batted balls.

The positive in the profile is that there has been a three-year trend of lower chase rates. Albies cut that number from 43 percent in 2022 down to 35 percent in 2023 to 33.5 percent in 2024. The contact skills are solid as well.

It will be interesting to see what 2025 looks like for Albies, as his value has the potential to sink.
