2013 analysis: In need of a starting pitcher after Ross Detwiler suffered an oblique injury, the Nationals called up Nathan Karns to make his major league debut against the Orioles on May 28. He was decent in his first start, doing enough to help the Nats beat Baltimore 9-3, but found trouble in his second two outings before getting sent back down in early June.
Karns was the first minor league starting pitcher the Nats called on in 2013, but proved to be the least effective. Both Tanner Roark and Taylor Jordan were much better and now sit ahead of Karns on the organizational depth chart. Late in the year Davey Johnson talked about Karns’ command issues and how he will have to improve his control to get back to the big leagues. “He was not ready. He has command issues. Stuff’s okay. But he has command issues,” Johnson said.
