2026 Fantasy Outlook
Foley missed most of the 2025 campaign following arthroscopic right shoulder surgery. The 30-year-old was subsequently non-tendered by the Tigers this offseason, but inked a one-year deal with the Giants a few weeks later. Foley's recovery will keep him out of action until midseason, but the right-hander will remain under team control through 2028. If he can return to pre-surgery form - he tossed his sinker in the upper 90's while inducing plenty of ground balls - he could quickly ascend San Francisco's high-leverage hierarchy. During his last full season in 2024, Foley racked up a team-leading 28 saves for Detroit. Read Past Outlooks

Scoreless outing in rehab game
PSan Francisco Giants
Shoulder
May 15, 2026
Foley (shoulder) earned a hold in Triple-A Sacramento's 6-5 loss to Round Rock on Wednesday, allowing one hit in a scoreless inning.
Analysis
Foley underwent season-ending arthroscopic surgery last May and was placed on the 60-day injured list Feb. 13. The right-hander began his rehab assignment with Single-A San Jose before moving to Sacramento after just one appearance. He entered Wednesday's game in the sixth inning and allowed a double but escaped without giving up a run, throwing 11 of his 14 pitches for strikes. The 30-year-old will likely require an extended ramp-up period and remains without a definitive timeline to return to the majors.

Past Fantasy Outlooks
2025
2024
2023
Foley's secondary offerings have been a work in progress, but he finally achieved success with his slider in 2024. The right-hander held opposing hitters to a mere .113 average and .145 slugging percentage that were among the best marks in the league for that pitch type. As expected, his usage of the slider increased by 14.1 percentage points - to 31.5 percent overall. Foley still favored his 97 mph sinker (54.7 percent usage), but it was crushed by opposing hitters (.299 AVG, 48.6 percent hard-hit). The 29-year-old still led Detroit with a career-high 28 saves and a 62.2% team save share, but he lost his grasp on closing duties for an extended period near mid-season and during the playoffs. Oddly, Foley only pitched once out of seven postseason contests, casting some doubt on his prospects for opening 2025 as the Tigers' closer. A shared role and more conservative save projection - perhaps 15-to-20 for Foley - might be a more realistic outcome.
Foley relied on his sinker more than ever in 2023 (69.3% pitch usage) after adding a tick of velocity (97.2 mph average) on the pitch. 45 of Foley's 55 total strikeouts came via his sinker, which also yielded a 57.1% groundball percentage that was 14th-highest among qualified relievers. The 28-year-old also set career-best marks in games played (70), innings (69.0), WHIP (1.16) and holds (28) while leading Tigers relievers with a 2.82 WPA. Foley briefly took over closing duties in August and finished the year with 7 saves despite lacking whiffs (17.9%) and strikeouts (19.9%). The right-hander has been one of Detroit's most reliable relief pitchers over the past two seasons and should reprise his high-leverage role again in 2024. Even more save chances could be in his future, especially if Alex Lange's control issues persist.
Foley will be one of the relievers trying to throw his name into the closing mix for the Tigers following their offseason trade of Gregory Soto. The big sinkerballer was one of the team's better relievers for most of 2022 before stumbling to the finish line in the final month. Foley doesn't get strikeouts but he boasts a career 56.8 percent ground ball rate and last year had just a 4.3 percent walk rate. The microscopic walk rate was atypical of the 27-year-old and he might need it to stick in order to make up for the lack of punchouts.

Latest Fantasy Rumors
Drawing trade interest
PDetroit Tigers
July 27, 2023
Mark Feinsand of MLB.com reports the Tigers have received "significant interest" for Foley on the trade market.
Analysis
The right-hander had a 3.88 ERA as a middle-relief option for Detroit last year, and he's excelled in a setup role this season with a 2.03 ERA, 1.06 WHIP and 39:10 K:BB over 44.1 innings. Foley isn't eligible for arbitration until 2025, so the Tigers aren't likely to move him without a strong offer.
