Boston Red Sox reliever Carson Smith will undergo Tommy John surgery, the team announced Tuesday.
Smith, who opened the season on the disabled list after being acquired by the Red Sox in an off-season trade with the Seattle Mariners, has made three appearances during the 2016 campaign, recording two strikeouts and one walk in 2.2 innings.
He was expected to pitch in a setup role this season after posting a 2.31 ERA with 92 strikeouts in 70 innings last year with the Mariners. Smith also converted 13 saves in 18 opportunities.
The 26-year-old was in the midst of his third MLB season.
Smith was selected by the Mariners in the eighth round of the 2011 MLB draft.
