As the third month of the season begins, fantasy baseball players are starting to show who they are in 2025. With two complete months of data, each player’s fantasy performance is starting to become less fluky and more representative. Is there still time for a player to adjust? Of course, but we can start to get a clearer picture of who is overvalued and undervalued in 2025 fantasy baseball.
Based on early performance, team usage, and changes to a player’s approach or mechanics, it’s already clear some players were undervalued in fantasy baseball draft rooms while others appear to have been overvalued.
This weekly piece will look at the past week to two weeks of fantasy baseball performances to see who should be considered overvalued and undervalued going forward. When necessary, I will reference the Fantrax top 500 rotisserie rankings for the 2025 fantasy baseball season.
Undervalued Fantasy Baseball Assets
(Stats are up to date as of May 26)
Jacob Wilson (SS – ATH)
Athletics rookie shortstop Jacob Wilson was an afterthought in most drafts this spring. He was picked somewhere between pick 350 to never in most drafts. Players like Brent Rooker and Lawrence Butler were getting all the fantasy love, and Wilson was basically an afterthought. That’s certainly not the case after his first two months of the season.
Wilson is hitting .350/.393/.495 with six home runs and four steals to go along with 28 runs and RBI. At just 23 years old, Wilson is a top-six shortstop this year, with the average plus the power/speed combo leading the way.
Most projection systems don’t think this is a fluke. He is projected to hit between .290 and .315 with 6-10 homers and 4-5 steals still to come this year. Whatever you paid for Wilson this spring, he has been well worth the investment.
Seiya Suzuki (OF/DH – CHC)
You may not have ever guessed it, but Seiya Suzuki is now a top-10 fantasy bat in rotisserie formats this season. His recent power surge, along with an above-average batting average, has propelled him to elite tiers this year, and the overall juggernaut that is the Cubs’ offense is the tide that raises all bats in this lineup.
Over the last two weeks, Suzuki is hitting .370/.418/.804 with four home runs and 15 RBI. Suzuki has always been a high-contact, hit-to-the-gaps kind of hitter, but his home run power has come out in full force so far in 2025.
At 14 home runs, Suzuki is already seven away from his career high in MLB. His hard-hit rate, barrel rate, and exit velocity are all up this season, and it’s now clear that a pick for Suzuki in the mid-80s this draft season was way too low.
Nathan Eovaldi (SP –TEX)
Father Time has been very kind to Nathan Eovaldi. Now in his 15th season, and at 35 years old, Eovaldi is still slinging it for the Texas Rangers and has a 1.60 ERA and 9.5 strikeouts per nine innings in 2025. He also has the lowest walk rate and lowest home run rate of his career, while he has kept his fastball velocity around 95 miles per hour this year.
The trick for Eovaldi has been a renewed reliance on keeping the ball on the ground. He has a 52% ground ball rate, which means his flyball rate (29%) is naturally going to be very low. A high strikeout rate plus a high groundball rate is the perfect recipe to defy time and continue to be dominant in fantasy baseball and in real-life baseball.
(NOTE: After writing this, Eovaldi left his Tuesday start with tricep fatigue, and he will undergo further testing.)
Overvalued Fantasy Baseball Assets
William Contreras (C – MIL)
When we talk about “overvalued,” we don’t mean that a player has NO value. Overvalued means that the price that was paid to acquire a player in drafts or the current, perceived value of a player is too high relative to what they are producing during the baseball season. This is the current situation with William Contreras.
Despite being drafted as a top-30 pick in two-catcher leagues, Contreras has been far, far away from that level of value. Contreras is hitting just .244/.363/.361 with five homers and five stolen bases. The on-base percentage is nice, but unless you are in an OBP league, Contreras has left a lot to be desired.
There have been reports that he is playing hurt. Specifically, there may be a broken bone in his hand that he is playing through. If it’s that reason or something else entirely, Contreras hasn’t been the player many drafted him to be this spring.
Brenton Doyle (OF – COL)
Even with his game-tying home run on Tuesday night, Brenton Doyle has not come close to paying off the investment you had to make at the draft table to secure his services this year. By the time the dust settled on draft season, Doyle was a top-75 pick after hitting 23 home runs and stealing 30 bases in 2024.
So far in 2025, Doyle is hitting .213/.276/.337 with four homers and six steals. That power/speed combo is nice, but Doyle – like the rest of the Colorado Rockies – is caught up in a general offensive funk that he hasn’t been able to shake all season. Is that the cause of his struggles this year? Perhaps, as there are signs he could improve in the weeks to come.
Doyle’s hard-hit rate and barrel rate are higher than last year. His BABIP is 30 points below his career average, and he is walking more and striking out less than in 2024. But his production is limited as long as the Rockies’ offense is as bad as it’s been this season.
Zac Gallen (SP – ARI)
Just about everything that could go wrong for Zac Gallen in fantasy baseball this year has gone wrong. Compared to 2024 (his third strong season in a row), 2025 has been a disaster. His ERA is up to 5.25, his walk rate and home run rate are way up. Strikeouts and groundballs are down. And according to Statcast, his barrel rate allowed is at an all-time high.
It’s not exactly clear what’s causing the dismal season for Gallen. His velocity on all pitches is largely unchanged. He is throwing his pitches with the same frequency as in 2024. His swinging strike rate and called strike rate are similar to 2024 as well.
The only thing that looks to be significantly changed is his ability to get hitters out with pitches outside the zone. His pitches thrown in the zone are up by more than six percentage points. And the frequency with which batters swing at pitches outside the zone is down almost five percentage points. Gallen’s stuff is good, but when it’s all in the zone, that’s where hitters have been able to tee off.
This is exactly the reason you should be buying Brenton Doyle:
“Doyle’s hard-hit rate and barrel rate are higher than last year. His BABIP is 30 points below his career average, and he is walking more and striking out less than in 2024.”
