Smith (elbow) will undergo Tommy John surgery next week, Alex Pavlovic of CSN Bay Area Sports reports.
It appears to be the worst case scenario for Smith, who has been dealing with elbow inflammation throughout spring camp. The left-hander remains optimistic the procedure will allow him to be ready for the beginning of the 2018 season and says he didn't want to risk a failed rehab process, which could have cost him even more time. Smith joined the Giants late last season, compiling a 2.95 ERA and 26 strikeouts in 26 games. Look for Josh Osich and Steven Okert to compete for the role of top left-hander in the San Francisco bullpen.
