The Athletics enter with confidence after outscoring Houston 32-7 in a four-game sweep. But they're 4-9 in JP Sears' last 13 starts. The lefty owns a 5.61 ERA in West Sacramento. Seattle counters with Luis Castillo, who has not allowed a homer in his last five starts while posting a 2.12 ERA. With rookie Jacob Wilson and Lawrence Butler (3 for 38 since All-Star Break) slumping, the A's lineup is less formidable after Nick Kurtz and Brent Rooker.
