The 2025 fantasy baseball season is almost here, and securing a top-tier first baseman can provide the power and consistency your team needs to dominate. First base remains a cornerstone position for offensive production, with players contributing high batting averages, home runs, and RBIs. Whether you’re looking for an elite option in the early rounds or a sleeper pick to deliver value later in the draft, this guide breaks down the best fantasy first basemen for 2025.

Top Tier: The Elite Sluggers

These players are the cream of the crop at first base, offering reliable production across all major fantasy categories.

1. Vladimir Guerrero Jr (Toronto Blue Jays)
   • 2025 projected stats: .312 AVG, 41 HR, 110RBI, 96R
   • Why He’s Elite: Guerrero continues to prove he’s one of the best hitters in the game, combining raw power with exceptional plate discipline. Batting in the heart of a potent Blue Jays lineup, he’s a lock for high run production. His durability and consistency make him an early first-round pick.
2. Freddie Freeman (Los Angeles Dodgers)
   • 2025 projected stats: .318 AVG, 28 HR, 101 RBI, 115 R
   • Why He’s Elite: Despite being in his mid-30s, Freeman remains one of the most reliable bats in fantasy baseball. His elite plate approach minimizes slumps, and hitting in a deep Dodgers lineup ensures plenty of opportunities to rack up runs and RBIs.
3. Bryce Harper (Philadelphia Phillies)
   • 2025 projected stats: .293 AVG, 36 HR, 107 RBI, 91 R
   • Why He’s Elite: Harper’s transition to first base in 2024 was seamless, and he continues to shine as one of baseball’s premier hitters. His ability to contribute across all five fantasy categories makes him a high-end option at the position. Paired with his elite plate discipline and power, Harper is a top-tier pick who brings both star power and reliability to your roster.
4. Matt Olson (Atlanta Braves)
   • 2025 projected stats: .276 AVG, 44 HR, 118 RBI, 93 R
   • Why He’s Elite: Olson’s power numbers are unmatched at the position. Anchoring the Braves powerful offense, he offers league-leading home run potential and massive RBI production. While his strikeout rate is higher than others in this tier, his power upside is worth the risk.

Second Tier: High-Value Contributors

These first basemen may not match the all-around dominance of the top tier but still provide excellent production.

1. Paul Goldschmidt (New York Yankees)
   • 2025 projected stats: .281 AVG, 28 HR, 92 RBI, 87 R
   • Why He’s Valuable: The veteran slugger continues to deliver steady production, combining a good batting average with solid power. Though he’s no longer in his prime, Goldschmidt remains a top-10 option thanks to his ability to contribute across multiple categories. A new hitter friendly ballpark should help add to his production.
2. Pete Alonso (Free Agent)
   • 2025 projected stats: .244 AVG, 42 HR, 102 RBI, 84 R
   • Why He’s Valuable: Alonso’s raw power is his calling card, and he’s a safe bet to hit 40+ home runs if healthy. While his batting average can be a drag, his contributions in HRs and RBIs make him a solid second-tier pick for fantasy picks.
3. Spencer Torkelson (Detroit Tigers)
   • 2025 projected stats: .281 AVG, 33 HR, 98 RBI, 82 R
   • Why He’s Valuable: Torkelson’s breakout season in 2024 has vaulted him into fantasy relevance. Still young, he’s only improving as the centerpiece of Detroit’s lineup. His growing power and improved plate discipline make him a rising star at the position.

Third Tier: Breakouts and Bounce-Back Candidates

These players have the potential to exceed expectations and deliver excellent value for your fantasy team

1. Christian Walker (Houston Astros)
   • 2025 projected stats: .267 AVG, 34 HR, 94 RBI, 79 R
   • Why He’s a Sleeper: Walker’s power and run production often come at a discount in drafts. He’s a consistent source of 30+ home runs and fits well as a mid-round selection for teams looking to bolster their power stats. A change of scenery in Houston could help benefit him as well.
2. Ryan Mountcastle (Baltimore Orioles)
   • 2025 projected stats: .261 AVG, 28 HR, 85 RBI, 77 R
   • Why He’s a Bounce-Back Option: Mountcastle battled injuries in 2024 but still displayed power potential. If he stays healthy, his upside in Baltimore’s young and dynamic lineup could surprise fantasy owners.
3. Josh Naylor (Arizona Diamondbacks)
   • 2025 projected stats: .283 AVG, 22 HR, 87 RBI, 75 R
   • Why He’s Underrated: Naylor’s steady contributions in batting average and RBIs often fly under the radar. He’s a great pick for managers who need balance rather than all-or-nothing power.

Deep Sleepers: Late Round Gems

1. Triston Casas (Boston Red Sox)
   • 2025 projected stats: .268 AVG, 26 HR, 88 RBI, 76 R
   • Why He’s a Breakout Candidate: Casas showed flashes of brilliance in 2024, and his growth as a hitter makes him an intriguing option for 2025. With Boston’s offense showing signs of some resurgence, Casas could be poised for a big year.
2. Andrew Vaughn (Chicago White Sox)
   • 2025 projected stats: .260 AVG, 24 HR, 82 RBI, 72 R
   • Why He’s a Sleeper: Vaughn has shown flashes of the talent that made him a top prospect. With more consistent playing time in 2025, he could finally put it all together and deliver strong numbers.
