One run from the 49ers in the bottom of the third was only enough to cut the Crimson’s deficit in half as Harvard held on to win the contest by a run.

HARVARD 2, CAL STATE FULLERTON 1

The Crimson came away with a win against host Cal State Fullerton (10-13) in a game that saw every run scored in the first inning of play.

A two-run homer off the bat of Lockhart gave Harvard a lead that it would maintain for the next six innings. After the Titans added a run in the bottom of the first, the two teams engaged in a defensive battle to the end.

The Crimson defense remained tight behind the efforts of senior pitcher Taylor Cabe. The South Carolina native pitched through the first five innings before being relieved with one out in the sixth. Cabe allowed only five hits and one run and recorded three strikeouts to earn Harvard the 2-1 win.

HARVARD 5, SAN DIEGO STATE 4

A late rally by the Crimson was enough to give the team a win over San Diego State in the opening day of the tournament.

Scoreless through three, both teams gained offensive momentum in the second half of the game. The Aztecs went ahead 1-0 in the bottom of the fourth before Harvard responded by loading the bases in the top of the sixth. A double by Callaway drove in two runs for the Crimson, followed by an RBI single from junior outfielder Alexa Altchek. Capitalizing on a San Diego State error, Harvard scored and extended their lead to 4-1.

The Aztecs battled back, earning two runs in the bottom of the sixth and one in the seventh. Yet an RBI groundout by Shively and close-out pitching from Duncan in the final inning allowed the Crimson to come away on top, 5-4.

“Overall, our games this weekend really were team efforts,” Lockhart said. “Everybody contributed to get the job done.”
