Cobb (4-5) gave up nine earned runs on 14 hits and two walks over five innings in Saturday's 9-2 loss to the Mariners. He struck out three.

The right-hander endured his worst start of the season against a Seattle offense that seems to finally be snapping out of a prolonged funk. Cobb got into trouble early by giving up three runs in the second after being staked to a 1-0 lead, and he continued to pitch to heavy contact the rest of the way. A pair of home runs surrendered to Nelson Cruz and Mike Zunino put a cap on his forgettable outing that included season highs in hits and runs surrendered. The 29-year-old will look to bounce back in a Thursday home start versus the White Sox.
