After another rought start on Tuesday, Diamondbacks right-hander Chase Anderson was optioned to Triple-A Reno. Anderson allowed seven runs--five earned-- over 4 2/3 innings in an extra-innings loss to the Pirates.
Anderson recently came off of the disabled list while battling a triceps injury. But after a strong start to the season, Anderson has struggled lately. He is 1-3 with a 7.52 ERA over his past four starts.
