HANOVER, N.H. — In a game that featured 16 walks, eight errors, four hit batters and two snow delays, the UMass Lowell River Hawks outlasted the host Dartmouth Big Green on Tuesday afternoon at Red Rolfe Field at Biondi Park by a 12-3 final. Colby Maiola drove in five runs, including a grand slam in the fifth that capped an eight-run outburst, helping UML (11-17) snap a four-game losing streak.

Sophomore Blake Crossing had four of the 12 hits for Dartmouth (7-15-1) as he and classmate Michael Calamari both extended their hitting streaks to nine games.

Dartmouth fell behind by two runs in the second, but managed to tie the game thanks to a solo homer courtesy of freshman Bennett McCaskill in the third, his second dinger in three days, and an RBI single off the bat of freshman Oliver Campbell to plate junior Steffen Torgersen, who had doubled with one-out in the fourth. But in the UMass Lowell half of the fifth, a leadoff walk — one of 11 issued by Big Green pitchers — proved to be troublesome.

After a sacrifice bunt, Russ Olive golfed an RBI double to left-center to break the tie, then took third when a pitch squirted away from McCaskill behind the plate. Another walk ended the afternoon for rookie reliever Carson Seymour (0-2), and Vinnie Martin greeted the new pitcher with a single to bring Olive home. A hit batter and another free pass forced in the third run of the inning.

But the River Hawks weren’t done as Kyle Maurice produced a sacrifice fly against the third pitcher of the stanza. The fourth walk of the frame brought Maiola to the plate, and he clubbed the first pitch he saw over the fence to the opposite field in left-center for his grand slam and a sudden 10-2 advantage.

The Big Green scored a run in their half of the fifth thanks to two of the six UML errors on the day, but the River Hawks tacked on solitary runs in the seventh — on Maurice’s first four-bagger of the year — and eighth to build their lead to 12-3. Still Dartmouth would not relent.

With the help of two more miscues in the field, the Green plated four runs in the eighth on just two hits, RBI singles by senior Hayden Rappoport and Calamari. Dartmouth continued to put the pressure on in the ninth, loading the bases with one down to bring the tying run to the on-deck circle. Sophomore Eric Stolt got a run home on a fielder’s choice to short in his first collegiate at-bat, but Kendall Pomeroy got the final out on a routine fly to right to end the game that took nearly four hours to play with the two snow delays included.

Nick Rand (1-1) earned the victory for UML with three innings of relief in the middle of the game, allowing two runs, one earned, on three hits and a walk while striking out two. The River Hawks used five pitchers on the day, but the only one to escape without surrendering a run was Ricky Constant, who threw a scoreless seventh.

Dartmouth featured six pitchers, beginning with sophomore Tyler Fagler who yielded a pair of runs on three hits and a pair of walks in his three-inning start to go with two strikeouts. Sophomore Alec Vaules was the only one to go unscathed, keeping UML off the board in the ninth.

The River Hawks had just nine hits, two each for Olive and Martin, while Joey Castellanos and Maurice each drove in two runs to support Maiola’s five RBIs.

Crossing reached base five times on the day with four singles and a walk from the leadoff spot in the order, and Calamari had two knocks of his own. Seven different Big Green hitters had one RBI, while Torgersen scored three times.

Dartmouth (3-2-1 in Ivy League) next travels to Ithaca, New York, this weekend to take on Cornell (5-14-1, 1-5 Ivy) in a three-game conference series. The two teams will play a doubleheader on Saturday starting at 11:30 a.m., followed by the finale on Sunday at 1 p.m. All three games will be streamed live on the Ivy League Network, now available on Apple TV, Roku and the ILN app for Android and Apple devices.

Notes: Crossing’s four hits were the most of his career and make him the third Dartmouth player with four in a game this year, joining Sean Sullivan (twice) and Matt Feinstein … UMass Lowell has won the last three games in the series, all played in Hanover, while Dartmouth won the previous two games, both in Lowell.
