Harrison (3-0, 1.66 ERA): Harrison has put up All-Star numbers in his first three starts, posting the American League's best ERA. He was given an 8-0 lead in the first inning of his last start, but he'll have his work cut out against a pitcher who has gone eight-plus innings in three-straight starts.
Shields (3-0, 2.76 ERA): Shields dominated the Twins in his last start, going eight innings and giving up the only run in a 4-1 victory. The bad news for the Rangers is they are hitting .212 against Shields in the last three years, the lowest average of any team that Shields has faced more than once.
