Rays starter Alex Cobb was not at his best as he failed to factor into the decision Friday night against the Mariners. The right-hander permitted four runs on seven hits and one walk while striking out five over six innings pitched.

Cobb has allowed three runs or more in two of his last seven starts. He is scheduled to make his next start Thursday at home against Boston. He is 0-1 with a 5.29 ERA in three starts against the Red Sox this season.
