Luke Scott homered, Melvin Mora hit a tiebreaking double in the fifth inning and the Baltimore Orioles beat the Washington Nationals 5-3 Friday night for their sixth win in seven games.

Left-hander Garrett Olson (3-0) struggled through five innings but remained undefeated in four starts since being recalled from Triple-A Norfolk on April 29. Olson allowed three runs and nine hits while striking out three.
