Kansas City Royals right-handed pitcher Nate Karns will miss the remainder of the 2017 season once he undergoes surgery to correct thoracic outlet syndrome this upcoming Wednesday in Dallas. Karns is currently on the 60-day disabled list, but will now be shut down for the remainder of the year.
Karns made eight starts this season and posted a 2-2 record with a 4.17 ERA and 1.191 WHIP. He struck out 51 batters in 45.1 innings of work, posting a new career-high in K/9 IP rate (10.1).
He struggled away from home this year, allowing seven home runs in 28.1 innings pitched on the road. His ERA in six games sat at 5.72, as compared to the 1.59 ERA he had at Kauffman Stadium in his first season of calling it home.
Kansas City acquired Karns from the Seattle Mariners back in January in a swap for outfielder Jarrod Dyson. He spent just a single season with the Mariners and alternated between the team’s rotation and bullpen.
His major league career began as a member of the Washington Nationals back in 2013, the same team that selected him in the 12th round of the 2009 MLB Amateur Draft out of Texas Tech. The first time he would be traded was when he was swapped to the Tampa Bay Rays, where he spent the next two years, before his trade to the Mariners.
Karns is one of 11 pitchers to start a game for the Royals this season, as the team’s fifth starter spot has consistently been in flux, despite the team’s ability to hang around the playoff picture.
