White Sox reliever Nate Jones underwent surgery to reposition a nerve in his right elbow and will miss the rest of the season.
The team has not announced the information.
Jones, 31, pitched 11 games in 2017 and left 2.31 ERA, plus 15 strikeouts and six innings in 11.2 innings. The right has been on the disabled list since May 4 because of a neuritis in his right elbow and has not pitched since he threw a blank inning in Detroit on April 28.
The good news is that the ligament was intact and was not the cause of the problem with his elbow.
Jones underwent Operation Tommy John on July 29, 2014. During the 2016 campaign he pitched in 71 games and finished tied for the top of the American League with 28 holds.
This campaign is the second of a three-year, $ 8 million deal between Jones and the White Sox. The team has options for 2019, 2020 and 2021.
