The San Francisco Giants agreed to a two-year, $22 million contract with veteran right-handed pitcher Adrian Houser, ESPN reported Tuesday.

The deal includes a club option for the 2028 season and was reported hours after San Francisco announced a one-year contract for free agent right-hander Jason Foley.

Houser, 32, split 2025 with the Chicago White Sox and Tampa Bay Rays and went a combined 8-5 with a 3.31 ERA in 21 starts.

Before spending 2024 with the New York Mets, Houser appeared in parts of seven seasons for the Milwaukee Brewers. In 173 career games (125 starts) since breaking in during the 2015 season, Houser is 40-44 with a 4.06 ERA and one save. A ground-ball pitcher, Houser has just 576 strikeouts with 282 walks in 733 2/3 career innings.

Foley, 30, last appeared for the Detroit Tigers in 2024 in a closing role and hade 28 saves in 32 opportunities. He did not pitch in 2025 due to shoulder surgery.

He will make $2 million with the Giants, ESPN reported.

In four MLB seasons spent entirely with Detroit, Foley has appeared in 210 games out of the bullpen and gone 7-9 with a 3.16 ERA and 35 saves. He's struck out 150 in 199 2/3 innings
