Undervalued, Overvalued Outfielders

Joey's outfield fantasy baseball draft sleepers, busts, values for points leagues in 2025. His undervalued, overvalued outfield picks for fantasy baseball drafts.

Welcome RotoBallers to our series about fantasy baseball points leagues, focusing on outfielders who are undervalued and overvalued based on fantasy baseball ADPs. If you haven't read about the other positions, be sure to check those out. Our fantasy baseball points rankings are also consistently updated to help you dominate your drafts. 

The outfield position always has the most players to choose from because you take into account everyone who plays left field, center field, and right field. As a result, there are many players at your disposal in drafts. Like every position, though, there are plenty of values/fades to note. 

So, let's dive in and look at the outfield landscape heading into fantasy drafts. We will look at five outfielders and determine whether they are overvalued or undervalued currently in 2025 fantasy baseball drafts.

Nick Castellanos, Philadelphia Phillies

ADP: 153.2

Philadelphia Phillies outfielder Nick Castellanos never finds himself going near the top of drafts. Last year, he had an average ADP around the ninth round and was usually the 25th or 26th outfielder off the board.

However, Castellanos always seems to outperform his ADP. The veteran slugger finished as the OF20 in points leagues last season, and he would have finished higher if it wasn't for a slow start. 

After hitting just .204 in the first 71 games, Castellanos batted .295 with 14 home runs, 22 doubles, and 56 RBI over the final 91 contests. That helped him finish with 23 home runs, 30 doubles, and 86 RBI on the season.

At this point in Castellanos' career, fantasy managers know what to expect from him. He'll finish with solid home run, double, and RBI numbers while playing almost every game. That should continue to be a large part of the slugger's game, as his expected slugging (.441) and launch angle sweet-spot rate (39 percent) ranked toward the top of the league in 2024. 

As a result, Castellanos is currently undervalued at his 153.2 ADP. He has hit at least 23 home runs in three of the past four seasons while driving in at least 85 runs in back-to-back years. The Phillies outfielder has also appeared in 319-of-324 games since 2023, making him a strong candidate to finish as a top-20 outfielder in fantasy once again. 

Verdict: Undervalued

Brandon Nimmo, New York Mets

ADP: 152.1

New York Mets outfielder Brandon Nimmo has been one of the more consistent fantasy options in recent years. Although he hit just .224 at the plate last season, he still posted strong numbers across the board while dealing with a foot injury for most of the year. Nimmo totaled 23 home runs, 25 doubles, 90 RBI, and 15 stolen bases across 151 games. 

Those numbers make the 31-year-old a nice target in point league formats in the middle-to-late rounds. He has hit at least 23 home runs in back-to-back seasons and just drove in a career-high 90 runs.

With Nimmo expected to hit behind both Francisco Lindor and Juan Soto in 2025, he should continue to finish with high RBI numbers. He has also scored at least 88 runs in three consecutive seasons.

Nimmo is one of the best outfield targets at this point in drafts. He is severely undervalued at his current 152.1 ADP, considering he'll be hitting in the heart of the Mets lineup and just finished as the OF15 in points leagues last season. The 31-year-old might not be the biggest name to select in drafts, but he will be a consistent fantasy option for your team. 

Verdict: Undervalued 

Adolis Garcia, Texas Rangers

ADP: 122.3

At this time last year, Texas Rangers outfielder Adolis Garcia found himself going in the third or fourth round of drafts. He had a 36.6 average ADP across multiple platforms, but a lot has changed since then. Garcia is coming off his worst season at the plate and finished with a rough .224 batting average. So, it makes sense why his ADP currently sits at 122.3. 

However, Garcia is going way too low in drafts. Although he had the worst offensive season of his career, he still hit 25 home runs, 27 doubles, and 85 RBI. Those three stats are arguably the most important in points leagues, and there's reason to believe that the Rangers slugger will bounce back offensively in 2025. 

His average exit velocity (91 mph), barrel rate (12.5 percent), and hard-hit rate (48.2 percent) all still ranked pretty well last season. On top of that, Garcia has entered the year with a new swing. While we don't know if this new swing will work, the 31-year-old said his goal is to hit 50 home runs in 2025. Even if he doesn't, another 35-plus homer season is surely attainable. 

Verdict: Undervalued 

Michael Harris II, Atlanta Braves

ADP: 46.0

Atlanta Braves outfielder Michael Harris II has been a top-50 pick in fantasy drafts for three straight years. That's due to the outfielder's potential at the plate. However, fantasy managers just shouldn't be taking him this high in point-league formats. As a matter of fact, he might not even be worth a top-75 pick in drafts. 

There's no doubt that Harris has shown his potential across his first three MLB seasons. His metrics across the board last year also back that up.

Harris's expected batting average (.284), expected slugging (.461), and hard-hit rate (47 percent) all ranked in the 82nd percentile or better. But taking a player in the fourth round who has never hit 20 home runs or driven in 65 RBI in a season is just too risky. 

Harris has also missed significant time due to injuries in each of the last three seasons. If he stays healthy, he'll likely be able to hit 20-plus homers, drive in upward of 70 runs, and steal at least 20 bases.

But staying healthy has been a problem for the former National League Rookie of the Year. So, fantasy managers shouldn't take him with a top-70 pick in points leagues this year. 

Verdict: Overvalued

Ronald Acuna Jr., Atlanta Braves

ADP: 26.7

Atlanta Braves outfielder Ronald Acuna Jr. missed almost the entire 2024 season after tearing his ACL at the end of May. That is certainly not great for his fantasy value this upcoming season. Not only will he not play in any spring training games, but Acuna is also expected to miss the first month of the season due to his recovery. 

While Acuna is one of the best fantasy options when healthy, it's hard to take him inside the top 30 when he is going to miss the start of the season. On top of that, the former National League MVP could run less and have reduced power at the plate in his first year back from that torn ACL. 

Ronald Acuna jr. just spoke to us for the first time since his acl surgery and he did a majority of it in English.

The last time that Acuna tore his ACL was during the 2021 season. The following year, he hit just .266 at the plate with 15 home runs, 24 doubles, 50 RBI, and 29 stolen bases across 119 games. Therefore, there is definitely some risk in taking the Braves outfielder this early in drafts. It will likely take him a couple of months to get back into the swing of things. 

Verdict: Overvalued
