CAMBRIDGE, Mass. —  Harvard scored in all four trips to the plate to win the rubber game of a weekend series against the Columbia softball team, 9-1, in five innings on Sunday at Soldiers Field.

Columbia (14-14, 6-3 Ivy) put up its run in the second inning on junior Amber Swinarski's RBI single to deep short. Harvard (12-14, 6-3 Ivy) scored four against starting pitcher Alexa Pinarski in the first before plating two unearned runs in the second. They added one in the third and two in the fourth to pull into a tie with the Lions in the Ivy League standings.

Katie Duncan pitched all five innings to earn the victory for the Crimson, allowing an unearned run on five hits and a walk. Pinarski (8-5) was charged with the loss for the Lions, surrendering six runs, four earned, on six hits and a walk over two-plus innings. The Lions threw Erin Gallo, Monique Benjamin and Madison Canby in relief.

Swinarski finished the game 1-for-2 with her first RBI of the season to lead the Columbia offense. Alexandra Yule pinch hit in the fifth and got the lone extra-base hit of the day with a double off Duncan. Genny Soltesz reentered to run and advanced to third on a passed ball but was stranded on a groundout that ended the ball game.

Kaitlyn Schiffhauer went 3-for-3 with a pair of runs and RBIs for Harvard. Elizabeth Shively was 2-for-3 with two driven in. Morgan Melito hit a three-run homer to spark the four-run first.

Harvard's first six runs all came with two outs, including all four in its first trip to the plate. Amanda Nishihira made a nice diving catch in foul territory to bring Melito to the dish with two on, but the Harvard sophomore lined a three-run homer down the left field line to give the home side the early lead. An RBI double later in the inning by Shively made it a 4-0 game.

Columbia got one of those runs back in the second. Harvard turned a double play after the Lions put the first two on base, but the inning continued with a single by Nishihira to place runners at the corners for Swinarski. The junior slapped a grounder to deep short and easily beat the throw, scoring Jordan Townsend from third to put the Lions on the board.

That would be all the offense Lions could muster. Schiffhauer dumped a two-out single to shallow center to make it a 6-1 game in the second before the Crimson went on to win in five.

Columbia plays at home for the first time in two and a half weeks when it hosts Monmouth on Wednesday. The Lions return to league action over the weekend with a series against Cornell.
