The right-hander left the Rays' 6-3 win over the San Diego Padres after throwing 117 pitches. He recorded 12 of 14 outs on strikeouts—four of them in the third, when a wild pitch on strike three allowed Will Venable to reach base. The Padres center fielder stole second and third base, then scored on a balk for a 3-0 lead.
Cobb departed after walking Yonder Alonso with two outs in the fifth. The Rays trailed 3-2 at the time.
