Outfield (OF) Fantasy Baseball Draft Values - Later-Round Sleepers, Upside Targets (2025)

RotoBaller's outfield fantasy baseball draft sleepers for the later rounds of 2025 drafts. These are sneaky fantasy baseball outfield value picks with upside.

Now that our mid-round fantasy baseball draft targets series has been published, it's time to focus on the later rounds and finding more fantasy baseball draft sleepers. The outfield position can get scarce once we get deeper into the draft, especially in leagues that require you to start five of them. Finding those hidden gems in the later rounds is equally essential, and we have some late-round OF picks that could be the key to unlocking your team's full potential.

Today, we're looking at some late-round outfielders for you to consider drafting in your season-long leagues this season. Are their ADPs undervalued? Will they make significant fantasy contributions and become a priority late-round draft target? Read on to see our take.

Victor Robles, Seattle Mariners

After providing little to no fantasy value from 2020 through the first half of 2024, a trade from Washington to Seattle seemed to jumpstart Victor Robles' career as the former top prospect had a strong end to the season. In 224 plate appearances after the All-Star break, Robles slashed .323/.385/.449 with a whopping 26 steals.

For those of you who added him mid-season, you probably finished higher in steals than you were sitting mid-season. Robles isn't a burner, but he's a solid runner and was highly efficient stealing bases last season, converting on 34 of his 36 attempts. The speed is why you want Robles this year and we just need to hope he can be adequate enough at the plate.

Poor quality of contact metrics don't bring much hope in the power department, but Robles had an 81% zone contact and 75% overall contact rate last season while only striking out 18% of the time

Roman Anthony, Boston Red Sox

In 119 games between Double-A and Triple-A in 2024, Boston Red Sox outfielder Roman Anthony slashed .291/.396/.498 with 18 home runs and 54 extra-base hits. The combination of contact, plate discipline, power, speed, and defense make him a true five-category asset. Starting with his contact and approach at the plate, Anthony starts with his hands and a slightly open stance. He uses a leg kick to create quite a wide stance but helps create good hand-to-hip separation.

Leading with his body, Anthony creates good lag with the bat thanks to his strong hands and electric bat speed. His bat speed ranks at the very top of all hitters in baseball. Given the bat speed, the power metrics are off the charts, though, as Anthony has a 90th percentile exit velocity near 109 mph.

Topping out north of 116 mph and showing solid average exit velocities, Anthony easily shows plus or better power. The biggest flaw with the power is a ground ball rate just shy of 48 percent which is something to watch. The plate discipline skills are impressive, and Anthony knows the strike zone as well as anyone. He chased just 21 percent of pitches out of the zone.

The contact skills follow along right with the discipline, as Anthony posted a 75 percent overall contact rate with an 83 percent in-zone mark. Anthony may not make the team out of spring training but expect him to get the call to the show in May. Providing power and speed and having a high floor thanks to his plate discipline and contact skills, his 297 ADP on NFBC is quite palatable.

Garrett Mitchell, Milwaukee Brewers

If you're looking for a late-round outfielder with upside, Garrett Mitchell is an intriguing target. In 224 plate appearances last season, Mitchell racked up eight home runs and 11 steals with a .255/.342/.469 slash line. He also had a 95th percentile sprint speed and a solid 11.2% walk rate.

However, the downside with Mitchell in 2024 was a 31.5% strikeout rate, 56.7% ground ball rate, and 71.7% zone contact rate. Mitchell has also dealt with various injuries over the last few years. If you're drafting Mitchell, the upside is there to finish as a Top 100 overall player for fantasy, given the power/speed blend.

Only three hitters had a bat speed > 75 mph (min 200 swings) and a sprint speed in the 90th percentile or higher...

ATC projects Mitchell with 13 home runs and 20 stolen bases, which is a great value at his NFBC price tag of 255. However, there are also plenty of downsides, which could turn into a pick you regret. He's one of the biggest boom-or-bust outfielders in 2025.

Kerry Carpenter, Detroit Tigers

In his first three seasons with the Detroit Tigers, outfielder Kerry Carpenter has mashed 44 home runs in just 868 plate appearances, including 18 in 296 plate appearances last season. It's easy to do the math and think that Carpenter could've approach 40 homers over a full season, but unfortunately, it's not as simple as that.

Tigers Outfielder Kerry Carpenter is @StevePhillipsGM's favorite fantasy baseball sleeper in the AL Central!

Yes, Carpenter has big-time power and proved that in 2024 with a 17.7% barrel rate and 46.4% hard-hit rate along with a close to league average 81.6% zone contact rate. However, Carpenter wasn't in the lineup very often against left-handed pitching, accumulating only 32 plate appearances last season with a .107/.194/.214 slash line.

The 2023 and 2022 seasons weren't as bad, but Carpenter still had a .099 ISO against LHP in 2023. The upside is here to be a Top 100 overall player for fantasy, but I'm slightly concerned that Detroit continues to sit him against most tougher left-handed pitchers.

Heliot Ramos, San Francisco Giants

It felt like we were waiting forever for San Francisco Giants outfielder Heliot Ramos to reach his potential, and in 2024, he finally hit on that upside. Ramos ranked in the 85th percentile or greater in barrel rate (14.5%), average exit velocity (91.5 MPH), hard-hit rate (47.5%), bat speed (75.2 MPH), and expected slugging (.481).

Unlike his previous MLB cups of coffee, Ramos was able to corral his strikeouts (26%) while making contact at a league-average rate (81.7 z-con%). In fact, only five qualified batters managed a barrel rate over 14% and zone contact over 80%, per Statcast: Juan Soto, Corey Seager, Yordan Alvarez, Bobby Witt Jr.—and Ramos. The improvements led to 22 home runs and a .269/.322/.469 slash (120 wRC+) in just 121 games.

If there is a red flag with Ramos, it's his splits: he posted a 1.189 OPS versus lefties but just .673 against righties. However, Ramos started 92% of the time against right-handers and proved a capable defender in left field. He should have a fairly long leash to improve against same-side pitching, giving the Giants OF depth chart.

If he even meets the ATC projections of a slash line of .251/.312/.430 with 20 home runs and seven steals, Ramos should add a slew of RBI, making him a well-rounded third outfielder with upside but also a minor risk given his splits.
