Giants To Sign Tyler Mahle

The Giants are closing in on a deal with free agent right-hander Tyler Mahle, reports Shayna Rubin of the San Francisco Chronicle. It’s a one-year pact, per Rubin. Mahle is a client of ISE Baseball.

Mahle is coming off an injury-riddled 2025 with the Rangers, though he was productive when healthy. The veteran righty was one of the most pleasant early-season surprises, pitching to a 1.64 ERA over the first two months of the season. Mahle allowed two earned runs or fewer in 11 of his first 12 starts to begin the campaign. He was knocked around for eight earned runs across his first two starts of June, then hit the IL with shoulder fatigue. Mahle returned for a pair of outings in September, allowing a run over 9 2/3 innings.

Persistent maladies have limited Mahle to just 125 innings over the past three seasons. He made nine starts across a season and a half with Minnesota, missing time with a strained shoulder and a forearm issue. It was a disappointing outcome for the Twins, who parted with Spencer Steer and Christian Encarnacion-Strand to land Mahle at the 2022 trade deadline. After signing with Texas in December 2024, Mahle missed the first four months of the year while recovering from elbow surgery. After three games with his new club, he went down with shoulder tightness and missed the rest of the year.

Mahle was routinely striking out more than a batter per inning during his peak years with Cincinnati, but those numbers have tailed off as the injuries have mounted. Mahle posted an uninspiring 19.1% strikeout rate last season. He sat at 92 mph with his fastball, down a couple of ticks from his best seasons with the Reds. The ERA estimators all suggest Mahle’s 2.18 ERA in 2025 should be viewed with skepticism. His xERA and xFIP were both above 4.00, while his SIERA was all the way up at 4.62. Mahle ran hot with home run luck (4.9% HR/FB), while also benefiting from a career-high 84.6% LOB%.

It was reported in mid-December that the Giants were still in the market for pitching after signing righty Adrian Houser. With Justin Verlander hitting free agency, the club entered the offseason with Logan Webb and Robbie Ray as the only guaranteed members of the 2026 rotation. Landen Roupp, who missed the final six weeks of the 2025 campaign with a knee injury, is also expected to be on the staff. Houser and Mahle are the favorites to round out the group.

President of baseball operations Buster Posey entered the offseason focused on adding to the rotation and the bullpen. While the club has been connected to some of the bigger names on the starter market, including Framber Valdez and Zac Gallen, the moves so far have been relatively minor. Houser came on board via a two-year, $22MM pact with a club option for a third season. The Giants added relievers Jason Foley and Sam Hentges on cheap deals. Mahle now joins the squad on a one-year deal.

Given the injury histories for Ray and Mahle, plus the limited track record for Roupp, San Francisco will likely need to lean on internal options for additional innings. Carson Whisenhunt, Carson Seymour, and Kai-Wei Teng all received opportunities last season, but none delivered useful results. Hayden Birdsong graduated from a long relief role to the rotation, but control issues led to a demotion to Triple-A. Keaton Winn and Blade Tidwell (acquired in the Tyler Rogers trade) missed time with injuries. Trevor McDonald might be the leading candidate to open the year as the sixth starter/injury fill-in. The righty closed the year with a pair of stellar outings, tossing six innings of one-run ball against the Dodgers and striking out 10 Rockies over seven frames.

RosterResource currently has the Giants’ payroll at $175MM for 2026. That mark doesn’t include Mahle’s deal or the $17MM payment owed to Blake Snell in mid-January as part of his deferred signing bonus. When adding in those considerations, the club is on track to comfortably exceed the $177MM it spent on payroll last season. The increase in expenses could be the reason the Giants ultimately rounded out the rotation with low-cost veterans in Houser and Mahle. A general hesitation by the front office to pursue long-term deals for starters likely also factored in.
