2025 Fantasy Outlook
Gallen turned in another solid but not ace-level season. His career 26.6 percent strikeout rate is very good, but not elite. Last year, it was a career low of 25.1 percent. After two years of declining walk rates, Gallen's 8.7 percent clip was a smidge worse than average. Yielding only 13 homers in 148 frames kept Gallen's ERA in check, but if the 2025 baseball is livelier than the 2024 version, Gallen's ratios could suffer, unless he returns to a lower walk rate. Gallen's velocity was in sync with past seasons, so it's a matter of throwing more strikes. In 2023, 64.5 percent of his pitches were strikes, compared to only 61.9 percent last season. There was a time when Gallen fanned 28 percent of batters and was a back end SP1. He's now a solid SP3, with SP2 upside if he can throw more pitches in the zone. Read Past Outlooks

Blanks Texas for 11th win
Gallen (11-13) picked up the win Wednesday, allowing four hits and a walk over six scoreless innings in a 2-0 victory over the Rangers. He struck out five.
Analysis
The veteran righty continues a late-season turnaround, delivering his sixth quality start in seven trips to the mound since the beginning of August. Over that stretch, Gallen has a 4-1 record with a 2.20 ERA, 1.05 WHIP and 33:10 K:BB through 41 innings. He'll look to keep rolling in his next outing, which is scheduled to come on the road early next week in San Francisco.

Past Fantasy Outlooks
2024
2023
2022
2021
2020
Gallen had a fantastic season and received some deserved votes for the Cy Young Award as he helped carry the Diamondbacks to their improbable World Series run. Most of his performance indicators were right in line with 2022 but better run support helped raise his wins while a near full-run jump in his ERA can be excused by the BABIP regression which we expected would come after his rather fortunate .237 BABIP in 2022. Simply put, there is not a performance issue to be concerned with as much as a workload concern. Gallen ended up throwing 243.2 innings in 2023, which was almost exactly double what he threw just two seasons ago. He managed a 52% increase in workload just fine from 2021 to 2022, but now we add another 32% increase in workload along with the stress of working in the postseason for the first time and we cannot help but wonder about the impact of that for 2024. 2023 was an excellent season, but it would not surprise us to see Gallen take a step back this season.

Latest Fantasy Rumors

Red Sox taking aim
The Red Sox have shown interest in acquiring Gallen, reports Rob Bradford of WEEI.com.
Analysis
Boston could use some rotation help and is looking and both Gallen and teammate Merrill Kelly. The 29-year-old Gallen is in the midst of the worst season of his career with a 5.60 ERA, 1.35 WHIP and 121:47 K:BB across 127 innings, though his expiring contract should mean the acquisition cost isn't too high. The right-hander entered the season with a 3.29 ERA through six MLB campaigns, and it's possible a change of scenery helps him regain that form.
