5 Outfield Fantasy Baseball Breakout Candidates

March 3, 2026

Joey's outfield fantasy baseball sleepers and 2026 breakout candidates. His favorite undervalued outfielders to target for fantasy baseball drafts based on ADP.

Every season, there are players who break out. These players then become fantastic value picks in fantasy baseball drafts. Just look at Pete Crow-Armstrong last season. Not many fantasy managers were in on him in drafts, but the Cubs outfielder went on to hit over 30 home runs and steal over 30 bases in a breakout campaign.

In this article, we will look at five outfielders who have the potential to break out in 2026. These outfielders are great picks in fantasy baseball drafts and should be considered sleepers in your leagues. All five of these outfielders are currently going outside the top-160 in NFBC drafts since February 15.

So, which outfielders will break out this upcoming season? Let's dive in and find out.

Dylan Crews, Washington Nationals

Washington Nationals outfielder Dylan Crews was one of the bigger fantasy busts last year. He only slashed .208/.280/.352 with 10 home runs, eight doubles, 27 RBI, and 17 stolen bases across 85 games and missed most of the season due to an oblique strain. Crews missed almost three months with an oblique injury he suffered in mid-May.

Despite putting up those subpar numbers, Crews still showed some encouraging things from a fantasy perspective. He hit 10 home runs and stole 17 bases in just 322 plate appearances and also posted a solid 9.7% barrel rate. With an 89th percentile sprint speed (29 ft/sec), the soon-to-be 24-year-old has the makings of being a 20-homer, 20-stolen base player in 2026.

Dylan Crews was disappointing as a rookie:

.208/.280/.352

But he kept his strikeouts in check (23.6%).

Fantasy-friendly game:
10 HR, 17 SB in only 322 PA

Worth a look as a post-hype sleeper Round 10 or later.

Things are certainly looking up for Crews heading into his second full major league season. He is finally fully healthy from that oblique strain, will play almost every day, and has the tools to break out. The Nationals outfielder is ready to rebound following that 2025 campaign and will enter the 2026 season on a "clean slate."

While Crews has been a bit disappointing to start his MLB career, he has such a high ceiling that he's worth a selection at his 164.1 ADP in NFBC leagues. This is a player who could steal upward of 30 bases and has the power to contribute in the home run category, too. Back in his first taste of the big leagues in 2024, he ranked in the upper half of the league in squared-up rate, hard-hit rate, and sprint speed.

So, expect him to be a much better fantasy option this season.

Addison Barger, Toronto Blue Jays

Toronto Blue Jays third baseman/outfielder Addison Barger is easily the best sleeper in fantasy baseball drafts. Even though the 26-year-0ld had a breakthrough campaign in 2025, there is a real chance that Barger takes his game to an even further level this upcoming season. That's how much potential he has in this Toronto offense.

Barger hit .243 with 21 home runs, 22 doubles, 74 RBI, and four stolen bases across 135 games last year. He was a consistent fantasy option for most of the season (outside of a rough stretch in the final month) and really came on strong in the postseason. The lefty batted .367 with three home runs, four doubles, and nine RBI in 17 postseason games.

As a result, Barger is a fantastic bargain at his 187.0 ADP in NFBC leagues. He ranked in the 85th percentile or better in average exit velocity (91.7 mph), hard-hit rate (51%), and bat speed (75.9 mph), and also ranked in the upper half in expected slugging (.462), barrel rate (11.4%), and launch angle sweet-spot rate (35.5%).

Fantasy managers shouldn't think twice about selecting Barger in the later rounds. He pulled the ball at a higher rate in 2025 (21.2% Pull AIR), and the injury to Anthony Santander (shoulder) now opens up a regular spot for Barger in the outfield. Santander will start the season on the 60-day IL, meaning the 26-year-old is set to be the team's starting right fielder on Opening Day.

That should be enough reason to draft Barger with confidence.

Daylen Lile, Washington Nationals

More fantasy managers should be in on Washington Nationals outfielder Daylen Lile. What he did during the final month of the 2025 season should not go unnoticed. He was arguably the best hitter in all of baseball in the month of September.

Lile slashed .391/.440/.772 with six home runs. three doubles, seven triples, 19 RBI, and one stolen base across 25 games in the final month. During September, his .391 batting average ranked second, his 19 RBI ranked tied for fifth, and his 230 wRC+ ranked second among all qualified hitters. He simply went on a heater to end the season.

Although we can't expect him to post those types of numbers again, there's much to like about Lile's game heading into the 2026 campaign. He ranked in the 100th percentile in both expected batting average (.302) and launch angle sweet-spot rate (44.2%) last year and also had an above-average xwOBA (.348), sprint speed (29.1 ft/sec), whiff rate (18.9%), and strikeout rate (16%).

Therefore, Lile is a sleeper pick at his 199.4 ADP in NFBC leagues. There's just too much potential here to pass over him in drafts. The 23-year-old could hit 20 home runs, steal over 25 bases, and hit around .300 this season. Make sure to select him in the later rounds because an all-around solid campaign could be in store for the Nationals outfielder.

Jac Caglianone, Kansas City Royals

It didn't take Kansas City Royals outfielder Jac Caglianone long to make his major league debut. After hitting .337 with 20 home runs, 14 doubles, and 72 RBI in 66 Minor League games last year, the Royals decided to call up their exciting prospect in early June.

However, Caglianone might not have been ready to face MLB pitching. He really struggled in his first taste of the big leagues, hitting .157 with seven home runs, six doubles, and 18 RBI across 62 games. His chase rate (38.5%) and squared-up rate (19.6%) both ranked poorly, and the young outfielder didn't show many signs of growth later in the season.

After facing numerous struggles in 2025, though, Caglianone should have a much better offensive season this year. Getting that first taste of big league ball could actually help the 23-year-old this offseason. He knows what he needs to work on this spring, and that could hopefully help him break out in a big way in 2026.

Caglianone also posted better metrics than fantasy managers might have realized. His expected slugging (.431) was 136 points higher than his actual slugging (.295), and he ranked in the upper half of the league in barrel rate (12%) and bat speed (77.4 mph). Given that the Royals outfielder finished with an 84.7% zone contact swing as well, a breakout campaign could be on the horizon.

If you are in need of some home runs later in drafts, look no further than Caglianone. The potential is there for a 25+ home run season in 2026. That makes him a nice target at his 203.8 ADP in NFBC leagues.

Jordan Beck, Colorado Rockies

Colorado Rockies outfielder Jordan Beck was an all-around solid fantasy contributor a season ago. He hit .258 with 16 home runs, 27 doubles, 53 RBI, and 19 stolen bases across 148 games. Beck doesn't necessarily excel in one specific category in Roto leagues, but he's a player who will put up solid numbers in multiple categories.

That's why Beck is worth a look as a breakout candidate in 2026. He plays in the most hitter-friendly ballpark at Coors Field and posted strong numbers at home a season ago. The 24-year-old slashed .303/.348/.466 with eight home runs, 18 doubles, three triples, 36 RBI, and 12 stolen bases across 76 home games.

That makes Beck a solid draft choice at his 231.8 ADP in NFBC leagues. Playing half of his games at Coors Field will likely lead to a batting average around .250 to go with 15+ home runs, 15+ stolen bases, and 60+ runs scored. Those are solid numbers for a player that has an 18th-round ADP. ATC projects the Rockies outfielder to finish with a .248 batting average, 15 home runs, 16 stolen bases, and 62 runs scored in 2026.

While there will be plenty of ups and downs with Beck, he could be a great late-round source of home runs and stolen bases. He has an above-average launch angle sweet-spot rate (36.9%), a solid bat speed of 73.2 mph, and an 83rd percentile sprint speed (28.7 ft/sec). Those three metrics make him a sleeper target with solid upside in fantasy baseball drafts.
