Matt Albers struck out Ramon Santiago to get out of the jam, and Jim Johnson pitched 1 1/3 scoreless innings to keep Hernandez in position to win.
"David was excited, but after the first inning he really settled down," Trembley said. "I was impressed once again, with not only his stuff, but his poise, his mound presence. And I know the guys are really getting a kick out of playing behind some of these new guys who are coming up because they're attacking the hitters."
Rookie outfielder Nolan Reimold broke a tie at 1 with a solo shot off Armando Galarraga in the fifth. It was his fifth homer and third in as many games. Scott, who put the Orioles on the board with a second-inning homer, hit a three-run shot in the eighth off Ryan Perry.
