 The Orioles won for the sixth time in seven games to open a two-game lead in the AL East. The Baltimore Orioles scored three runs in the third inning and went on to defeat the Seattle Mariners 4-1. Ryan O'Hearn drove in the first two runs with a double and scored on a Ryan Mountcastle single. O'Hearn then added a solo home run in the fifth inning to complete the Baltimore scoring. Dean Kramer, pitching in his first game since May, struck out eight Mariners batters over five shutout innings to pick up the win.
