Colton Cowser of the Orioles posted the best offensive game of his young career, driving in four runs with two doubles and a sacrifice fly in a 7-1 win on opening day at Fenway. It was the second multi-hit game of his career. Cowser’s strength so far at the plate came from drawing walks. He has yet to hit a home run, but now owns six doubles in 76 at bats. He nearly doubled his RBI total of five.
