Garrett Richards has decided to have season-ending surgery to repair ulnar collateral ligament damage in his right elbow.

Richards will be a free agent this coming offseason. He is 5-4 with a 3.66 ERA for the Los Angeles Angels.

The right-hander had been limited to six starts each of the past two seasons. He missed most of 2016 due to a UCL injury and suffered from biceps nerve irritation last year.
