Outfield Fantasy Baseball Draft Values
Brenton Doyle, OF, Colorado Rockies
Colorado Rockies outfielder Brenton Doyle produced a 20/30 campaign in 2024, but struggled to parlay that success into his 2025 season. The right-handed hitter did have a strong two-month stretch from July 1 through September 1, where he hit .349 with a .940 OPS over a period of 46 games, but despite that productive stretch, he still finished with an underwhelming .233/.274/.376 slash line with a .282 wOBA in 138 games.
The former fourth-round draft pick hit just 15 home runs and stole only 18 bases with his 96th percentile sprint speed, while his 65 wRC+ was tied for the worst in all of baseball among qualified players. If there is some hope for 2026, it's that the 2x Gold Glover should be healthy, as he dealt with a quad issue earlier last season and a shoulder injury late in the campaign, which could have led to some of the underperformance.
So long as he doesn't start and finish as poorly as he did last year, when he hit .182 outside of the aforementioned two-month hot stretch, the 28-year-old should have a more productive year and threaten 20/20 again. That upside has him ranked a bit higher on RotoBaller, at 149 overall, compared to his NFBC ADP of 163 overall.

Jo Adell, OF, Los Angeles Angels
Los Angeles Angels outfielder Jo Adell delivered a breakout season in 2025, slugging 37 homers, ninth most in baseball, while driving in 98 RBI, tied for 17th in the league. The former top prospect has always had elite raw power, and incremental improvements in his contact ability helped fuel a 96th percentile barrel rate (17.2%) and an 87th percentile hard-hit rate (50%).
However, the 26-year-old still has flaws in his profile, most notably with his plate skills, and he also saw a noticeable dip in sprint speed, stealing 10 fewer bags than he did in 2024. After ranking no lower than the 86th percentile in sprint speed in previous years, Adell fell to the 63rd percentile in 2025 and attempted just six steals.
Jo Adell this Spring Training:
.359 AVG
14 H
3 HR
7 RBI
1.067 OPSWill 2026 be even better than 2025 for Adell? pic.twitter.com/mz57rYQ1vf

His batted ball profile and contact skills will keep his batting average as a clear weakness. However, he remains an appealing mid-round power bat projected for 30+ home runs and the possibility of double-digit steals.

Jakob Marsee, OF, Miami Marlins
Jakob Marsee's Miami debut was loud, hitting .292/.363/.478 with five homers and 14 steals in 234 plate appearances. What will the 24-year-old do for an encore? Likely a bit of everything. With 46 steals on the farm in 2023, 51 in 2024, and 47 in just 429 plate appearances at Triple-A last season, fantasy managers can expect the steals to keep flowing.
His 8.0% percent rate of Brls/BBE, 111.1 mph max exit velocity, and 93 mph average airborne exit velocity are all around league-average and should translate to a HR total in the teens. The biggest knock on Marsee is batting average risk, and his .357 BABIP probably won't repeat.
Jakob Marsee enjoyed a productive 2025 season, posting a 133 wRC+ over 234 PA w/ 2.1 fWAR. He showed great plate discipline, highlighted by his 19.9% Chase% & made plenty of in zone contact coupled w/ a .278 xBA & .346 xwOBA.

— Running From The OPS (@OPS_BASEBALL) January 23, 2026
However, his expected batting average of .278 would still be a fantasy plus, and his 28.1 ft/sec Statcast Sprint Speed may be high enough to perform consistently above his xBA.
Marsee also demonstrated strong plate discipline last season, posting a 9.4 BB% and 20.5 K% backed by double-digit walk rates and a sub-23 K% at every MiLB stop. Miami's leadoff man should deliver plenty of runs scored in an improving lineup, making Marsee a solid value at his 147.87 ADP.

Lawrence Butler, OF, Athletics
Athletics outfielder Lawrence Butler (knee) broke out in his first full season at the big leagues in 2024, slashing .262/.317/.490 (130 wRC+) with 22 homers and 18 steals across 451 plate appearances.
Butler profiled as an ascending star entering 2025, and while he still had solid power-speed numbers with 21 homers and 22 steals, the 25-year-old's strikeout rate ballooned to 28.4%, and his quality of contact regressed as he battled through a knee injury, leading to an underwhelming .234/.306/404 (96 wRC+) line.
The 26-year-old underwent surgery in the offseason to repair a torn patellar tendon in his right knee, and he is expected to be ready for the start of Spring Training. The 25-year-old outfielder is a prime candidate to bounce back with improved health.
Butler's splits against left-handed pitching are an area he still needs to improve, though he projects as the Athletics' everyday right fielder and brings 30-30 upside in 2026. However, fantasy managers should expect a 20/20 season as ATC projects Butler to slash .241/.307/.424 with 21 home runs and 18 steals in 2026.

Chandler Simpson, OF, Tampa Bay Rays
Tampa Bay Rays outfielder Chandler Simpson had a strong showing in his first season as a big leaguer, although a midseason demotion and a lack of power were some drawbacks for fantasy. The demotion was not a result of poor hitting, as the Georgia Tech product was batting .285 with 19 steals in 35 games prior to being sent back down at the end of May, and in all, he hit .295 with 44 steals in 109 games, tied for second most in all of baseball despite playing just two-thirds of the season in the big leagues.
With an 89.8 percent contact rate and 98th percentile K% of 9.8 percent (and a history of strong contact rates in the minors), expect the strong batting average to continue, while fantasy managers who draft the speedster could be getting the likely 2026 stolen base leader; however, it comes at a cost.
The 25-year-old owns one career home run, which came in the minors, meaning there is a clear liability in the power categories (HR, RBI). Even so, the left-handed slugger can be had late in many drafts, going around 150 overall per his NFBC ADP, while RotoBaller ranks him much more favorably, at 132 overall.
