Athletics: Oakland begins a four-game series at Baltimore on Monday when Marco Estrada (0-0, 2.76 ERA) opposes Andrew Cashner (1-1, 5.40). Estrada allowed two hits and three runs — two earned — in 5 1/3 innings in his last start but did not factor in the decision.
Astros: RHP Justin Verlander will start on Monday when Houston begins a three-game series at home with the Yankees. Verlander will look to get back on track after allowing six hits and four runs in four innings of a loss to Texas in his last start.
