Coming into the 2026 fantasy baseball season, second base is a fascinating position. While it’s not a flashy position full of top stars, there are some strong options at the top of the rankings, with a few strong fantasy baseball sleepers to consider once the top names are off the board. If you miss on the very top options, it might be a good idea to grab a couple 2B sleepers to see how the early part of the season plays out.
Whether you prefer season-long leagues, DFS contests or DraftKings Best Ball, DK Network will have you covered throughout the upcoming season. I began this series with fantasy baseball sleepers at catcher and at first base, and in this post, we’ll look at the three second base sleepers that I’m watching to outperform expectations this season.
Jorge Polanco, New York Mets
Moving from coast to coast, Polanco will be playing for the Mets this season after spending the last two seasons in Seattle. It’s surprising to see him going outside the top 15 at 2B after his big year last year and strong postseason performance.
Polanco hit .265 with 26 homers in 138 games last season, all his highest marks since 2021. The switch-hitter hit .308 against lefties with a .380 wOBA, while hitting 21 of his 26 homers against righties, with a .342 wOBA. Most of his production came at home, but he’ll actually be getting a slight park upgrade with the move to Citi Field from pitcher-friendly T-Mobile Park.
Even if he doesn’t match last year’s impressive numbers, the 32-year-old has been consistent with at least 14 homers in five straight years and a wOBA of .333 or higher in six of his last eight seasons.
The early word out of Mets camp is that Polanco could be the team’s preferred option at cleanup hitter this year. If he hits in the heart of the productive order with Juan Soto, Bo Bichette and Luis Robert Jr. around him, he should be in a prime position to produce better run-production stats than his ADP indicates. Most of my fantasy baseball sleepers are young players on the rise, but in this case, Polanco is a veteran player whose value has slipped too low.
After proving he still had plenty in the tank last year, Polanco should be ready to run it back with a good first year with the Mets.
Colt Keith, Detroit Tigers
Keith is a potential post-hype sleeper to watch this season with the Tigers. He brings extreme positional flexibility after playing 1B, 2B and 3B throughout last season. That flexibility will be key for his team again this season after Gleyber Torres accepted the qualifying offer, and it can also help him be a nice piece to fortify the infield depth on your fantasy team as well.
In 2024, as a 22-year-old, Keith played 148 games and hit .260 with 13 homers and a .301 wOBA. He made steady progress last season, hitting .256 with 13 homers in 137 games. His walk rate increased from 6.5% to 10.3% and his barrel rate jumped from 5.6% to 9.2% and his hard-hit rate climbed from 35.0% to 43.7%.
His improvement in average exit velocity was the 14th-largest of all MLB, and his hard-hit rate was the ninth-largest improvement. The increase in selectivity and improvement in quality of contact did boost his wOBA a little bit, but it’s also a good sign that he could continue to improve in 2026, since he’s still only 24 years old coming into the year.
Keith will likely play 3B for the most part this year, but his multi-positional eligibility only makes him a better fit as he looks to continue his steady, impressive progress. Coming into spring training, he’s only the No. 25 2B in ADP, so he can be an elite value if he steps up in again this season.
Christian Moore, Los Angeles Angels
Moore makes sense as a late-round, end-of-the-draft option if you’re looking more for a young prospect as a “swing for the fences” pick to fill in at 2B as one of your fantasy baseball sleepers. Moore was a top-10 pick from the 2024 MLB Draft, and the Angels fast-tracked him to the majors, as they have with several prospects over the last few years.
The 23-year-old played games at Single-A, Double-A and Triple-A, getting in exactly 300 plate appearances and hitting .271 with a .366 wOBA. The Halos called him up for his debut in June, and in 53 MLB contests, he hit only .198. However, he did have seven homers, three of which came in his final call-up for the last 14 games of the season.
The Angels acquired Vaughn Grissom from the Red Sox and re-signed Yoan Moncada, so they do have some options in the infield if Moore needs more time in the minors. However, Moore’s batted-ball metrics indicate he wasn’t quite as bad as his results show last season. In Triple-A, he hit .292 with five homers, four stolen bases and a 41.5% hard-hit rate.
The big question with Moore is whether he’s ready to make the jump to the majors or will start again in the minors. Since he’s the No. 37 2B in ADP, he’s a deep-league sleeper with upside at this pointn and can be a late-round dart throw if you’re looking for depth at the position.
