Marco Estrada has a 2.76 solid ERA. And he's been dominant against these Orioles hitters, holding them to a career 14-of-82 clip (.171). The A's offense should pick it up against Andrew Cashner, who hasn't been great this year so far, and who last year allowed 10 runs over 6.2 innings against Oakland. Cashner's relief will come from a bullpen that has a 7.97 ERA and .333 average against.
