Guthrie was in command throughout, giving up just two singles, one to Ryan Raburn in the 2nd and to Will Rhymes in the 5th.

Nick Markakis hit his 11th homer of the year, a solo shot on an 0-2 pitch from Rick Porcello leading off the 3rd to give the O's a 1-0 lead. The O's made it 2-0 in the 7th. Robert Andino led off with a single to left and later scored on a Julio Lugo single to left center. The Orioles had 13 hits in the game with 12 singles.
