Chicago White Sox right-handed relief pitcher Nate Jones will miss the remainder of the season after undergoing nerve repositioning surgery on his right elbow on Tuesday, according to Scott Merkin of MLB.com.
The White Sox had originally placed Jones on the 10-day disabled list with elbow inflammation back on May 4.
Jones had been rehabbing, but experienced a setback.
The 31-year-old had pitched in 11 games out of Chicago’s bullpen this season, recording a 2.31 ERA and allowing nine hits while striking out 15 batters over 11.2 innings of work.
Jones, who played his college baseball at Northern Kentucky University, was originally selected by the White Sox in the fifth round of the 2007 MLB June Amateur Draft.
He broke into the majors in 2012 and immediately impressed, going 8-0 across 65 relief appearances during his first season. Across 71.2 frames of action, Jones pitched to the tune of a 2.39 ERA and surrendered just 67 hits. While did he walk 32 hitters, he served up only four home runs and registered 65 strikeouts.
The following season, Jones went 4-5 and posted a 4.15 ERA in 78 innings, but advanced metrics indicated that the relatively high ERA was just a bit of bad luck, as Jones owned a 2.64 FIP and fanned 89 batters while giving up only 69 hits.
In 2016, the Butler, Ky. native went 5-3 and tallied a 2.29 ERA over 70.2 frames of action. He allowed only 48 hits and issued just 15 walks, resulting in a sparkling WHIP of 0.892. Jones also struck out 80 hitters.
The White Sox are currently 38-49 and sit nine games behind the Cleveland Indians for first place in the American League Central Division.
