The San Francisco Giants bolstered their bullpen by signing right-hander Jason Foley to a one-year Major League contract worth $2 million. The 30-year-old former Detroit Tigers reliever missed the 2025 season due to shoulder surgery but is expected to return mid-2026. Foley's addition comes amid the Giants' efforts to rebuild their relief corps after key departures.
The San Francisco Giants agreed to terms on a one-year Major League contract with right-handed pitcher Jason Foley, a move aimed at deepening their bullpen options. The deal, reported by ESPN's Jesse Rogers as worth $2 million, was announced on Tuesday. Foley, a 30-year-old native of Manhasset, N.Y., spent four seasons with the Detroit Tigers from 2021 to 2024, appearing in 210 relief outings with a 3.16 ERA, 7-9 record, 35 saves, 150 strikeouts, and a 1.24 WHIP over 199.2 innings.
In his final full season in 2024, Foley recorded 28 saves, ranking fifth in the American League, and pitched in 69 games, tied for 12th in the league. After the All-Star break that year, he posted a 2.70 ERA over 26.2 innings, holding opponents to a .179 batting average, contributing to Detroit's postseason qualification. The previous year, in 2023, Foley appeared in 70 games, tying for 10th in the AL, and generated 1.6 Fangraphs WAR, sixth among AL relievers. From 2022 to 2024, his 189.1 innings ranked fifth among AL relievers, while his 75 saves plus holds placed 10th.
Foley underwent surgery in May 2025, performed by Dr. Keith Meister, to repair the anterior capsule in his right shoulder, causing him to miss the entire Major League season. He was designated for assignment by the Tigers in November and became a free agent. The Giants anticipate Foley starting the 2026 season on the injured list but returning to the mound by mid-year, potentially serving as a closer given his save totals.
This signing follows the Giants' trade of Tyler Rogers and Camilo Doval at the deadline and Randy Rodriguez's Tommy John surgery. San Francisco also added left-hander Sam Hentges on a one-year, $1.4 million deal and claimed Reiver Sanmartin off waivers from the Cincinnati Reds. These newcomers will complement existing relievers including Ryan Walker, Erik Miller, José Buttó, Joel Peguero, and Spencer Bivens.
