HANOVER, N.H. — Alex Rosenberg missed just one shot all night in scoring 31 points to lead the visiting Columbia Lions to an 84-72 victory over Dartmouth on Friday night at Leede Arena. Columbia (18-10, 7-4 Ivy) shot 58.1 percent as a team and drained 13-of-25 from long range to counter the Big Green (9-16, 2-9 Ivy), which canned 8-of-14 from deep and 49.0 percent overall.

Senior Tyler Melville drilled a career-high four three-pointers in leading Dartmouth with 19 points, while sophomore Connor Boehm hit 7-of-10 field goals, including a pair of triples, in tallying 17. Joining the duo in double figures were sophomores Brandon McDonnell and Alex Mitola with 10 apiece.

Rosenberg, meanwhile, scored 22 of his 31 points in the second half, finishing the night 6-of-7 from the floor with a pair of three-pointers and a perfect 17-of-17 at the foul line. But he wasn’t the only Lion on the prowl as both Maodo Lo and Steve Frankoski rained down four triples in recording 16 and 14 points, respectively.

Dartmouth began the game well as Melville sank a 17-footer and McDonnell got loose on the break after a John Golden steal to tomahawk a dunk for a 4-0 advantage. But Rosenberg scored the next five points with a three-pointer and a pair of free throws before Lo dropped his first triple for a sudden 8-4 Lion lead.

Melville and Boehm kept the Big Green within striking distance for a bit, but after back-to-back baskets by Boehm, Columbia went on a 10-1 spurt on the strength of two Frankoski three-balls for an 11-point lead at 23-12. It was Melville who brought the run to an end with another trey, and after McDonnell ended a stretch of over four scoreless minutes with a bucket, Frankoski and Melville once again traded three-pointers.

Following a Rosenberg jumper with 3:34 left in the half, Columbia owned a 28-20 edge. But Dartmouth strung together seven straight points, the last five coming at the charity stripe, to close the gap to one with a minute and a half on the clock. Once again, the two teams dropped dueling trifectas, this time by Meiko Lyles and Boehm. The Lions then held for the final shot, which they pulled off with a Jeff Coby dunk just before the buzzer sounded to take a 33-30 lead into the locker room.

Melville led all players at the intermission with 13 points, while Rosenberg and Frankoski had nine each for the Lions. Columbia hit 12-of-22 (.545) from the floor and 7-of-14 (.500) from the perimeter, but Dartmouth made four more free throws and forced four more turnovers (9-5) to keep the game close.

In the second stanza, the difference oscillated between five and eight points for most of the first six minutes until Lo cranked another three-pointer and Isaac Cohen hit a short jumper in the paint to put the Lions up 11, 54-43. Four straight points by McDonnell knocked the Dartmouth deficit back to single digits briefly, but when Rosenberg got the rim for a layup with just under 10 minutes play, the Lions never let the Big Green closer than 10 the rest of the night.

Twice Columbia built its bulge to 18 points, the first time on Frankoski’s final long ball of the night with 6:31 to go. Three-pointers by Melville, sophomore Kevin Crescenzi and freshman Eli Harrison, as well as a three-point play the hard way by rookie Wesley Dickinson, helped bring the Big Green closer, but it was not enough as the Lions hit their final 12 free throws in the last six minutes of play. Rosenberg ruined his own perfect night when he missed a three-pointer from the right corner with 24 seconds to play.

Freshman Luke Petrasek was most responsible for Columbia gaining the edge on the boards, 27-18, with a game-high 10 rebounds. Golden paced Dartmouth with six caroms, but the 18 rebounds are the fewest for the Big Green in over three years.

Lo not only was 5-of-7 overall and 4-of-5 from behind the arc, he also dished out a game-high seven assists while Cohen added six more. Mitola gave out four helpers while pilfering the ball three times for the Green.

Dartmouth will honor its lone senior in Melville before its final home game of the season tomorrow evening when Cornell (2-23, 1-10 Ivy) comes to Leede Arena for a 7 p.m. tip. Columbia heads to Cambridge, Mass., to take on league-leading Harvard (23-4, 10-1 Ivy) at 7 p.m. as well.

Notes: Neither Columbia nor Dartmouth had scored 70 points against the other in the previous 16 meetings … the Big Green have lost seven straight games since sweeping Penn and Princeton on Jan. 31 and Feb. 1 … Dartmouth has topped 70 points just twice in the 14 games since the new year arrived, yet scored at least 70 in seven of the first 11 games of the season … Rosenberg is the second opposing player this year to tally at least 30 points in Leede Arena. Dyami Starks of Bryant had 35 back on Nov. 13. The arena record is 39, held by Vermont’s Eddie Benton set back on Jan. 11, 1994.
