Identifying early sleepers is one of the best ways to gain an edge in fantasy baseball drafts. Whether it’s a breakout hitter poised to take the next step or a pitcher ready to exceed expectations, finding undervalued players can make a huge difference in your championship pursuit. To help you stay ahead of the competition, we asked our Featured Pros to highlight their top early sleepers for the 2025 fantasy baseball season. Their expert insights will help you target the right hitters and pitchers before the hype catches up. Let’s dive into their picks!

Fantasy Baseball Sleepers

Jordan Walker (OF – STL)

“Jordan Walker sank last year behind another season where he wasn’t given a chance to be the guy. This year, he is locked into a starting role. He spent the offseason shortening his swing to get to the ball quicker. That is key, as he still has tremendous 30-plus home run power and can barrel consistently. If he cuts the strikeouts and makes more contact, he has a chance to be a top-100 fantasy player in 2025.”

Zach Neto (SS – LAA)

“The hitter outside the top 150 overall in ECR that I expect to be this year’s biggest sleeper is Zach Neto of the Los Angeles Angels. Neto may be slipping in early drafts due to his offseason shoulder surgery. He still is unable to make full-length throws across the infield, but he is now able to take batting practice. In 2024, Neto Neto was the Angels’ best player, as he delivered .249/.318/.443 with 23 home runs, 34 doubles, 77 RBIs, and 30 stolen bases across 155 games. Keep an eye on him during spring training to monitor his progression from offseason surgery. He’s good for at least a 20/30 season.”

Matt Wallner (OF – MIN)

“Matt Wallner had a very productive 2024 in limited action. He hit 13 home runs in 267 plate appearances and slashed .259/.372/.523. With the departure of Max Kepler, there is everyday playing time for Wallner, and RosterResource has him batting at the top of a decent Minnesota lineup. His OBP has been north of .370 each of the last two seasons, and even with a dip, he should still collect plenty of runs and give you 20+ homers. He may not be the most exciting sleeper option, but there is excellent potential for a guy going in the 23rd round of drafts.”
