After recovering from major shoulder surgery, veteran righty Jason Foley joins the San Francisco Giants’ bullpen to provide veteran stability and high-leverage experience following a minor-league rehab stint.
The San Francisco Giants signed right-handed pitcher Jason Foley to a one-year, $2 million major-league contract on December 16, 2025.
Here on Sunday, July 12, he could make his season debut. Foley, 30, spent his first four seasons with the Detroit Tigers.
After missing the majority of the 2025 season due to right shoulder surgery, Foley was officially reinstated from the 60-day Injured List.
Foley completed his rehabilitation assignment, and he'll replace fellow righty Spencer Bivens. Officially, the team announced that Bivens would be optioned to Triple-A Sacramento.
Jason Foley: By the numbers
Foley is no stranger to pitching in the big leagues. Sure, it's been quite some time, but he pitched in 60-plus games for the Tigers from 2022-24. Overall, he's appeared in 210 games.
To no surprise, Foley has been a reliever in every single on of those appearances. He sports a 7-9 record in his career, having won three games in both the 2023 and 2024 seasons.
Foley is coming off a 3.15 ERA season, one that saw him carry a 1.18 WHIP which turned out to be the second lowest of his career. The New York native has a career 3.16 ERA, so his number from 2024 echoes what he's done throughout his career.
For reference, Foley had a 2.61 ERA in both 2021 and 2023. Keep in mind, he only pitched in 11 games in '21 but appeared in 70 two years later. After having a 0.3 WAR in his first season, that number skyrocketed to 2.0 in 2023.
Foley has 150 career strikeouts to 51 walks, so his 2.9 K/BB ratio is right under three strikeouts to every walk. That's still a great number to have, and he's a solid arm to have in the bullpen as he brings 35 career saves and 45 career holds.
Bivens optioned after two appearances
The 32-year-old likely wasn't going to be with the Giants for long, but he was extremely solid in his two appearances. Bivens pitched 1.0 inning in both of them, but he did need 31 pitches to record three outs on Wednesday, July 8. That said, neither of the runs he gave up were earned so that certainly helped.
Bivens struck out three batters and walked just one. All three hits he allowed came in that July 8 game, and to no surprise, that's the appearance where he walked the batter. Overall, there's certainly a chance he returns to the majors, but for now, this was the move that had to be made.
