Miguel Gonzalez, the No. 3 starter for Baltimore, gave up a leadoff single in the fifth to Marlon Byrd, who scored on Ruben Tejada's sacrifice fly. Gonzalez struck out four and walked one in five innings.

McLouth hit leadoff homers in the third and fifth. The first one came against Dillon Gee, slated to start the third game of the season for the Mets against San Diego. The second one was off Jeremy Hafner, lined up to start the fourth game.

Hafner gave up two more home runs, to Chris Davis and Steve Pearce. The right-hander left his previous outing Tuesday against St. Louis when he was hit on his pitching elbow by Carlos Beltran's one-hopper.
