San Francisco Giants pitcher Johnny Cueto might need Tommy John surgery.
Manager Bruce Bochy said Monday there is a "strong possibility" the pitcher could undergo the season-ending surgery, per Alex Pavlovic of NBC Sports Bay Area.
Cueto was placed on the 10-day disabled list Monday with a right elbow sprain.
The 32-year-old opened his season in impeccable fashion by going 3-0 with a 0.84 ERA, 26 strikeouts and six walks over his first five starts.
However, the two-time All-Star landed on the disabled list with right elbow inflammation May 1, marking his second DL stint in the span of a month after starting the season on the shelf because of an ankle issue.
Cueto eventually returned to the mound, but his diminished velocity remained a concern. Now nine starts into the 2018 campaign, he has gone 3-2 with a 3.23 ERA and a 2.92 strikeout-to-walk rate.
So long as Cueto is out of action, the onus could be on Ty Blach to replace his spot in the rotation.
