Fantasy Baseball First Basemen Sleepers 2023

5. Spencer Torkelson, Detroit Tigers

Last season was a disaster for the Tigers, including Torkelson. Pegged by many as a preseason Rookie of the Year candidate, the former first-overall draft pick simply wasn't ready for the majors. His first season was a massive disappointment, yielding just 8 home runs, 28 RBIs and a .604 OPS in his first 110 games. Expect better performance from the 23-year-old in 2023, however, especially after Detroit overhauled its coaching staff in the offseason. New hitting coaches could help Torkelson get back on track, and he should feel more comfortable in the bigs after a full season to acclimate.

4. Brandon Belt, Toronto Blue Jays

After 12 seasons with the San Francisco Giants, Belt is finally getting a change of scenery. It couldn't come at a better time for the 34-year-old, whose numbers should see a significant boost in Toronto. Not only is he joining a stacked Blue Jays lineup, but he's also going to a much better hitting environment, especially after the team moved in the outfield fences this offseason. Belt's had trouble staying healthy in recent seasons, but his pop has remained mostly intact and could be capable of producing his second 20-homer campaign in three seasons.

3. Seth Brown, Oakland A's

The A's lost 102 games last year and Brown doesn't have much of a supporting cast, so he isn't getting the attention he deserves. He built on his 2021 breakout with an even better campaign in 2022, playing everyday for the first time in his career and improving his numbers across the board. On top of swatting at least 20 home runs in each of the last two seasons, he's also a surprisingly good baserunner for his size, swiping 11 bags in 13 attempts last year. That type of impact on the basepaths is hard to find at first base and boosts his value considerably, as does his outfield eligibility.

2. Triston Casas, Boston Red Sox

Big things are expected from Casas this year, who's viewed as an AL Rookie of the Year candidate thanks to his advanced power and plate discipline for his age. The 23-year-old showed plenty of both in his cup of coffee last season, smacking 5 home runs and drawing 19 walks in 27 games for Boston. The former first-round draft pick is one of the Red Sox's top prospects for a reason, and there's 25-to-30-homer potential here if he lives up to his potential.

1. Joey Meneses, Washington Nationals

Meneses dominated after replacing Josh Bell last summer following the latter's trade to the San Diego Padres. The 30-year-old helped many players win their fantasy leagues by slashing .324/.367/.563 with 13 homers and 34 RBIs in 56 games following his MLB debut in August. Obviously, some regression is to be expected and he doesn't have a ton of help in Washington's lineup, but there's no reason he can't smash 30 homers with a full complement of at-bats.
