The San Francisco Giants have agreed to a one-year contract with free-agent right-hander Tyler Mahle, bolstering their starting rotation. Mahle, who posted a strong 2.18 ERA in 2025 with the Texas Rangers, adds depth alongside recent addition Adrian Houser. The deal, first reported by the San Francisco Chronicle, comes as the Giants prepare for the 2026 season.
The San Francisco Giants enhanced their pitching staff on December 31, 2025, by agreeing to a one-year free-agent contract with veteran right-hander Tyler Mahle, according to multiple reports including MLB.com and the San Francisco Chronicle. Financial terms of the deal remain undisclosed, but the agreement follows the Giants' recent signing of Adrian Houser to a two-year, $22 million pact on December 19.
Mahle, 31, enjoyed a solid 2025 campaign with the Texas Rangers, going 6-4 with a 2.18 ERA over 86 2/3 innings, striking out 66 and walking 29. Despite ongoing injury challenges—including right shoulder fatigue that sidelined him for over three months and a prior Tommy John surgery—he has been effective when healthy. Since 2020, Mahle has maintained a 3.61 ERA across 473 1/3 innings.
A California native and seventh-round pick by the Cincinnati Reds in 2013, Mahle debuted in 2017 and spent five-plus seasons with the Reds, compiling a 31-38 record with a 4.35 ERA and 637 strikeouts in 593 2/3 innings. He was traded to the Minnesota Twins ahead of the 2022 deadline in exchange for prospects Spencer Steer and Christian Encarnacion-Strand. After one injury-limited season with Minnesota, Mahle signed a two-year, $22 million deal with the Rangers in December 2023, returning from Tommy John rehab late in 2024.
The Giants, who entered the offseason needing multiple starting pitchers, now project Mahle to join Logan Webb, Robbie Ray, Houser, and Landen Roupp in the 2026 rotation. Depth options include Hayden Birdsong, Carson Whisenhunt, Trevor McDonald, and Blade Tidwell. Mahle's addition addresses a key area of need without draft pick compensation, as he did not receive a qualifying offer from Texas.
This move underscores the Giants' strategy to build a competitive rotation amid broader MLB free-agency activity on New Year's Eve.
