Gray (2-1) gave up one run on three hits and a walk over seven innings while striking out 11 in Wednesday's 4-1 win over the Marlins.
It was by far Gray's best start since coming off the DL, and the right-hander now has a dominant 19:3 K:BB in 13 innings over his last two outings. He'll face a much tougher test Tuesday on the road in Cleveland.
