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 before the hype catches up. Let’s dive into their picks!
Fantasy Baseball Sleepers
Which hitter outside the top 150 overall in ECR do you expect to be this year’s biggest sleeper and why?
Fantasy Baseball Sleepers: Hitters
“Second base is light this year, and this time last season, people couldn’t wait to overpay for Jackson Holliday. Now, he’s being drafted at pick No. 199, which is an equally ridiculous overreaction. He’s made off-season adjustments, ditching the big leg kick, and Holliday is still very much the guy who slashed .304/.443/.486 over 218 minor-league games. We expected too much from the 20-year-old last season, and we’re not expecting enough this season. He could end up being a 20/20 player in 2025 with a decent BA and counting stats, depending on his lineup spot.”

“Gobble up hefty portions of Heliot Ramos this draft season. The Giants left fielder finds the barrel 14.5% of the time and has an average exit velo of 91.5mph. He uses the whole field and has a hard hit rate of 47.5%. Pass on someone like Riley Greene and snag Ramos five rounds later.”

“Are we totally sure Victor Robles’ numbers in Seattle to end 2024 were complete fool’s gold? He looked like a completely different player compared to his tenure in Washington. Robles had 3.1 WAR, batted .328, and stole 30 bases…in just 77 games! His xBA was much lower at .257, so of course, some regression is coming from that .388 BABIP. But he was on pace for over 60 stolen bases in a full season, and even in an environment where steals are up across the board, that’s still a needle mover. He’s also, somehow, only 27 years old still, and it wouldn’t be entirely unheard of for a 27-year-old former elite prospect to finally put it all together at the plate. I’m not saying Robles is a league winner, but as a guy being drafted outside the top 225 picks, I think he’s a great bet to return lots of value in certain formats.”

“Victor Robles after 200 is a steal this year. After being traded to Seattle, in 77 games, Robles hit .328/.393/.467 with 4 HRs and 30 SBs. Yes, double those numbers, and the full-year pace was 8/60. I don’t expect 60 SBs, but 7/40 with a .300 average looks nice, especially when guys like Brice Turang, Andres Gimenez, Xavier Edwards, and Masyn Winn are going multiple rounds earlier.”
– Brandon ‘B_Don’ Myers (Razzball)
“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.”

“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.”
– Jeff Boggis (Fantasy Football Empire)
“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.”
