OAKLAND -- For the first three innings, Felix Pena was unhittable. That changed in the fourth.
After needing only 25 pitches to retire the first nine batters he faced, Pena came undone, allowing the first seven batters in the fourth to reach base, which sparked a six-run inning that doomed the Angels in a 10-0 loss to the A's on Wednesday night at the Coliseum.
Nick Martini and Matt Chapman led off the fourth with consecutive singles, and both scored on Jed Lowrie's double to center field.
