Thornton allowed four runs on three hits with one walk and three strikeouts across three innings in a no-decision against the Tigers on Saturday.
The 25-year-old is headed in the wrong direction, as again he lasted under 55 pitches in a start. During his last two appearances since the All-Star break, Thornton has given up nine runs and two home runs in 4.1 innings. He threw six scoreless innings against the Orioles just before the break, but still, in four of his last five appearances, he's yielded at least four runs. Overall, Thornton is 3-7 with a 5.45 ERA, 1.54 WHIP and 100 strikeouts in 99 innings. He will pitch next against the Rays at home Friday.
