Giants breakout reliever recommended to undergo Tommy John surgery

A breakout season for Giants reliever Randy Rodríguez has come to an unfortunate end. The team announced that multiple doctors have recommended the All-Star righty undergo Tommy John surgery (relayed by Justice delos Santos of The Mercury News). Rodríguez will make his decision this weekend, but it’s tough to see this going any other way.

The procedure will almost certainly cost him the entire 2026 season. Rodríguez had taken over the ninth inning after San Francisco traded Camilo Doval to the Yankees at the deadline. He would’ve been the favorite for the closer role going into next year. The 25-year-old turned in a 1.78 earned run average while striking out more than a third of opponents over 50 appearances. He collected his first four career saves and picked up 13 holds.

There are 102 pitchers who have thrown at least 50 innings out of the bullpen this season. Rodríguez is seventh among that group in ERA and eighth in strikeout percentage. He has the fifth-highest gap between his strikeout and walk rates. He’s among the top 30 relievers in swinging strikes. He had emerged as one of the league’s best young relievers.

Elbow injuries have been the only real concern over his first two big league seasons. Rodríguez missed six weeks in the second half of the ’24 campaign to elbow inflammation. He avoided surgery at the time, and his 97-98 mph fastball and wipeout slider carried him through the first five months of this season. An elbow sprain sent him back to the injured list this week, and it seems the ligament damage is severe enough that he’ll need to go under the knife.

Rodríguez entered this season with 148 days of service time. He picked up a full service year in 2025 and will do the same in ’26, assuming he indeed undergoes surgery and spends the entire season on the injured list. He’ll qualify for arbitration for the first of four times as a Super Two player during the 2026-27 offseason. The Giants will need to carry him on the 40-man roster over the offseason, but can place him on the 60-day injured list at the beginning of Spring Training.

The injury is a massive hit to a bullpen that already looked like a weakness going into the offseason. Ryan Walker, who will finish this season in the closer role, has had a strong second half after a rocky start. He’ll be back in high-leverage spots. José Buttó, acquired from the Mets in the Tyler Rogers trade, will be in the setup mix. They’re the only two locks.

Joel Peguero has huge stuff, but has made three career appearances. Journeyman lefty Matt Gage has pitched well, yet he’s a 32-year-old without big velocity. Erik Miller, their top left-hander in the season’s first half, has been rehabbing an elbow sprain of his own. The Giants could look at putting Hayden Birdsong back into the bullpen after he struggled to throw strikes as a starter. Even if they do that, they’ll need to add multiple arms from outside the organization during the winter.
