On the other side of the ball, Penn sophomore left-hander Mark Lacerenza was equally impressive in the early going, retiring the first 11 batters he faced before being chased from the game in the fifth inning.
"It was a little discouraging in the early going," Crockett said. "But we were getting some good swings and confident we could get to him at some point. I was getting a little nervous, but I knew eventually we put in a couple hits and take advantage of some walks to score a couple runs."
Hitless and trailing 2-0, the Crimson bats finally came alive in the bottom of the fifth with four runs on four hits.
Tiring quickly, Lacerenza walked a pair and Carter singled to load the bases with none out.
Pinch-hitting for sophomore second baseman Faiz Shakir, Junior Scot Hopps took Lacerenza's 2-2 delivery to the gap in right, clearing the bases and cashing in three runs with a standup double.
Two batters later, Mager made it 4-2 with another RBI double to the gap in right as the Crimson got all the offense it would need behind the pitching of Crockett.
NOTES: Junior John Franey was hit by his own foul ball in the tenth inning and forced to leave the game...Harvard has now defeated the Quakers nine straight times... Penn tri-captain Kevin McCabe was ejected at the end of the first game of the doubleheader for arguing with the umpire.
