In his last seven starts, Mahle is 4-0 with a 2.04 ERA and is coming off of a career-high 6 2/3 innings in a win over the Cubs Friday. The progress of his secondary pitches, including his slider, means not relying as much on his four-seam fastball.
Carrasco came off the DL on Friday and held the A's to three runs on seven hits in 5 1/3 innings, ending with seven strikeouts and no walks. The big righty is 7-4 with a 2.97 ERA in 18 career appearances in Interleague play.
