ITHACA, N.Y. — Dartmouth built up a 20-point lead in the second half then withstood a run by host Cornell to depart Newman Arena with a 78-66 victory, earning a split of the season series with the Big Red. Freshman Evan Boudreaux led the Big Green (9-14, 3-6 Ivy) to their second road win of the season with 22 points and a season-high 18 rebounds for his third straight double-double and ninth of the season.

Cornell (9-14, 2-7 Ivy) suffered its fifth straight loss since downing Dartmouth in Hanover on Jan. 30, but Darryl Smith collected 22 points on 9-of-13 shooting, including 3-of-5 from behind the arc.

Boudreaux struggled a bit from the floor, coaxing just six of his 17 attempts to go through the iron, but one was a three-pointer and he knocked down 9-of-11 at the foul line for his third-straight 20-point game as well. Joining him in double figures were sophomores Taylor Johnson (14) and Miles Wright (13).

Dartmouth shot just 40.7 percent (24-of-59) for the game, but held Cornell to a mere 35.5 percent (22-of-62) and 24.2 percent (8-of-33) on three-pointers. The Big Green also dominated the boards, led by Boudreaux, with 46 rebounds to just 32 for the home team.

In the first half, Dartmouth had its long-range sights set, hitting all five of its three-pointers on the night in the opening 15 minutes, starting with triples by Wright, Boudreaux and junior Mike Fleming for the Big Green’s first points and a 9-5 lead.

Cornell briefly took a 10-9 lead on a three-pointer by Troy Whiteside and a pair of foul shots by JoJo Fallas, but Boudreaux answered back with two freebies of his own, and Dartmouth never trailed again.

A 9-0 run in the middle of the half, fueled by the first of two Johnson three-pointers, built up the Big Green lead to 12 at 25-13. Twice Dartmouth extended its advantage to 14, once on a layup by senior Connor Boehm and again on a Boudreaux layup. By halftime, the Big Green had a comfortable 36-24 lead.

Boudreaux already had his double-double when he went to the locker room for the intermission with 10 points and 11 rebounds. Dartmouth featured a balanced attack as eight players contributed points to the cause, and hitting 5-of-8 three-pointers in the half didn’t hurt, either. The Big Red, meanwhile, was just 7-of-28 (.250) overall and 2-of-14 (.143) from distance with three players each scoring five points.

In the second half, the Big Green went hard to the basket, hitting six of their first seven shots, all of which were layups, to increase the gap to 19 at 48-29. A Boudreaux steal and a breakaway dunk by Wright kept the difference at 19 with 14:32 to play, and when Boudreaux sanke the first of two foul shots, Dartmouth had its largest lead of the night at 55-35.

At this point, Smith decided to put Cornell on his shoulders, scoring the next 12 Big Red points with a pair of trifectas to cut that 20-point deficit in half at 57-47. A Fallas long ball with 7:25 to play made it a single-digit deficit for the first time in over 18 minutes of action at 59-52. And another Smith trey after two Wright free throws brought the Big Red within six, 61-55, with 4:42 on the clock.

With the memory of letting a nine-point lead slip away in the final 3:32 against Cornell in the first meeting, Dartmouth got a pair of putbacks from Boudreaux and sophomore Cameron Smith to push the advantage back to 10, but the game wasn’t over quite yet. Matt Morgan, who finished with 16 points for the Big Red, sank two free throws, and when a backcourt violation was called against Dartmouth, Johnson was hit with a technical foul for his fifth foul of the night. Morgan canned two more freebies, and the difference was six again with 2:27 left.

Boudreaux calmly responded by converting a three-point play, sending Cornell center David Onuorah to the bench with five fouls. Morgan rained down a long three-pointer to keep the Big Red within six, but Dartmouth hit all eight of its free throws in the final 1:16, and freshman Guilien Smith punctuated the victory with a dunk for the Big Green’s final points.

The foul line was kind to Dartmouth — the Ivy League’s leading free throw shooting team — as it converted 25-of-32 (.781). Cornell had a higher accuracy at the charity stripe, sinking 82.4 percent, but barely had half as many attempts (14-of-17). And while the Big Red forced 17 turnovers and committed 15, the Big Green had a much better success rate in turning those miscues into points, 17-8.

Dartmouth will try to extend its winning streak to three games when it plays at Columbia (18-8, 7-2 Ivy) on Saturday at 7 p.m. Cornell, meanwhile, will try to snap its five-game skid when it hosts Harvard (10-15, 2-7 Ivy) at 6 p.m. Both games will be streamed live on the Ivy League Digital Network.

Notes: The last Dartmouth player with more than nine double-doubles in a season came 23 years ago. Crawford Palmer collected 11 in his only season with the Big Green in 1992-93 … Boudreaux is averaging 21.1 points and 11.6 rebounds in the nine Ivy League games to date … the Big Green have won two straight games in Ithaca after suffering through a nine-year drought.
