Cobb (1-2) allowed eight runs on eight hits and two walks and lasted just three innings in a loss Tuesday against the White Sox.
Cobb has allowed 15 runs over 4.1 innings in his past two starts after a promising beginning to his injury shortened 2016. He was touched up for a pair of home runs and has now allowed five in as many starts. His ERA is a brutal 8.59, a hard number to believe after he posted a 2.87 ERA in 166.1 innings last season.
