Keuchel aims to go 4-0 against A's in '17

After a bounceback start his last time out, Astros lefty Dallas Keuchel will toe the mound in Sunday's series finale against the A's to prove he's back to his All-Star form.

Keuchel, aiming to avoid a four-game sweep, will oppose A's righty Kendall Graveman (4-4, 4.70 ERA) at the Coliseum. Keuchel's track record against the A's this season is impressive -- a 3-0 record and an 0.83 ERA in three starts. He spun 7 2/3 innings against the Mariners last time out, allowing two runs. After the win, Keuchel explained his recent diversion: "I kind of lost my cool."

Astros manager A.J. Hinch said Keuchel can appear disappointed when the results don't match his high expectations.

"He's never out of control, he's never overly emotional on the mound," Hinch said. "But inside I think he expects perfection, so whether he makes a mistake, if the umpire makes a mistake -- if the hitter gets a good pitch -- internally he can get a little bit frustrated."

Graveman, meanwhile, beat the Astros on Aug. 18, allowing two runs in six innings. Since that outing, he has a 5.29 ERA in three starts. However, Graveman has much better home stats (3.17 ERA) compared to his road outings (6.75 ERA).
