Ryan Mountcastle doubled in two runs in the sixth inning to put Baltimore ahead for good, and the Orioles got an effective performance from their realigned bullpen in a 5-4 victory over the Colorado Rockies on Saturday night. Baltimore has won four straight and seven of eight to move 33 games over .500 (81-48) for the first time since the end of the 1997 season. The victory enabled the Orioles to maintain their three-game lead over second-place Tampa Bay in the AL East.
