As expected, Giants starter Johnny Cueto will undergo season-ending Tommy John surgery on Thursday to repair his ulnar collateral ligament, Alex Pavlovic of NBC Sports Bay Area reports. Manager Bruce Bochy had said on Monday that there was a “strong possibility” Cueto would have to go under the knife.

Cueto, 32, finishes his 2018 campaign with a 3.23 ERA and a 38/13 K/BB ratio in 53 innings across nine starts. The right-hander is likely to miss the vast majority — if not the entirety — of the 2019 season as well.

Cueto is under contract through at least 2021, earning $21 annually. The Giants also hold a club option for 2022 worth $22 million with a $5 million buyout.
