SAN FRANCISCO -- What has seemed inevitable became official Wednesday as the Giants announced right-hander Johnny Cueto will undergo Tommy John surgery Thursday in Los Angeles.
The procedure, which will be performed by Dr. Neal ElAttrache, is expected to sideline Cueto for approximately one year, likely rendering the Giants' No. 2 starter unavailable until late next season.
San Francisco closer Will Smith underwent Tommy John on March 30, 2017, and pitched in his first regular-season Major League game this year on May 2.
Giants general manager Bobby Evans pointed out that Cueto's diligent approach toward physical conditioning lifts hopes for a successful recovery.
