BINGHAMTON, N.Y. -- Freshman Zack Tower came through again on Saturday, enabling the UMass Lowell baseball team to salvage a split of a doubleheader at Binghamton University.

Tower last Tuesday hit a sixth-inning pinch-hit grand slam to lift UMass Lowell past Brown, 5-3, in the second game of a doubleheader.

On Saturday, Tower was the River Hawks' DH, driving in the go-ahead run with a double in the top of the seventh inning as UMass Lowell defeated Binghamton, 3-2.

Binghamton (18-21) won the nine-inning first game, 10-6.

UMass Lowell is now 18-17.

The teams play again on Sunday in Vestal, N.Y., at 1 p.m..

UMass Lowell senior right-hander Mike Calzetta went the seven-inning route in the second game to improve to 4-1 with a 2.53 ERA. Calzetta allowed two earned runs on five hits and three walks. He struck out three.

Jacob O'Keefe put Lowell up 1-0 in the second inning with an RBI single that scored Matthew Sanchez (single). The River Hawks went ahead 2-1 in the third when Danny Mendick singled and eventually scored on an outfield throwing error.

Tower's one-out double to left center in the top of the seventh scored Strom (infield hit) with what held up as the winning run.

Sanchez, Ian Strom and Joe Consolmagno each had 2 hits for UMass Lowell.

In the first game, Matt Mottola and Strom each had 2 hits and 2 RBI. Mottola's 2 RBI came on a 2-run homer in the seventh inning that cut Binghamton's lead to 7-6. The homer was Mottola's third of the season.

But Binghamton came back with three runs in the bottom of the seventh.

UMass Lowell in the fourth inning had scored four runs to go up 4-3, with two of those runs scoring on a single by Kelly Rooney. The Bearcats had similarly responded with three runs in the bottom of the fourth to go ahead for good.

Senior right-hander Shane Beauchemin (3-4) was the losing pitcher in the first game (4ip, 7h, 6r, 6er, 2bb, 2k).
