Rondon was optioned to Triple-A Toledo after struggling and taking the loss Sunday against the Twins, Evan Woodbery of MLive.com reports.

EDGE Analysis

Rondon couldn't find the strike zone on Sunday, as he walked two batters on a total of nine pitches. Both runners came around to score, which put the Tigers down 6-4 and bumped Rondon's ERA up to 10.91. Manager Brad Ausmus said Rondon's first few pitches were "alarming" and "weren't real close," so he wasted no time pulling the 26-year-old. Rondon has some talent, but clearly he needs to refine his control and grow as a pitcher. He'll try to do that at Triple-A and could rejoin the MLB club when rosters expand in September.
