Kansas City, Mo. ? The Royals have placed left-hander Jason Vargas on the disabled list with a torn ligament in his elbow, an injury that typically requires season-ending Tommy John surgery.

Vargas left his start against Pittsburgh on Tuesday night after throwing just 26 pitches. He had an MRI on Wednesday that revealed the extent of the injury.

The Royals filled his spot in the rotation by recalling Yordano Ventura. The hard-throwing right-hander had been sent to Triple-A Omaha just a day earlier to work on his inconsistency and rebuild some confidence after a string of poor starts.

Vargas, who is 5-2 with a 3.98 ERA, was instrumental in the Royals’ run to the World Series a year ago. He went 1-0 with a 3.52 ERA in three postseason starts.
