HANOVER, N.H. — Senior Miles Wright led four Dartmouth players in double figures with 21 points in the penultimate game of his career, and fellow senior Taylor Johnson converted two free throws with 19.1 seconds left to help stave off a late Columbia rally to defeat the visiting Lions on Friday night at Leede Arena, 80-78. With the win, the Big Green (7-19, 3-10 Ivy) denied Columbia the opportunity to clinch a berth in the Ivy League Tournament, playing the spoiler role to perfection.

Kyle Castlin matched his career-high with 22 points for Columbia (8-18, 5-8 Ivy) while Mike Smith added 20 more, but the Lions could not quite dig out of the 19-point hole they faced with 8:20 to play.

“You never know what you’re going to get when you know it’s final weekend [of the season],” said Dartmouth head coach David McLaughlin. “We told the guys, ‘We have a really bright future and we’re playing for that, but we’re also playing for our seniors.’ Our seniors played well, but everyone also played well for those seniors.”

Dartmouth enjoyed a fine shooting night from the floor, hitting 30-of-53 (.566) overall and 12-of-24 (.500) from the perimeter. Six of the eight Big Green players that saw action hit more than half of their shots with Wright hitting 21 on 7-of-13 shooting, 3-of-6 from downtown and 4-of-5 at the line, including two key free throws with 1:30 to play.

Sophomore Brendan Barry added 14 points on 5-of-7 from the floor, while senior Taylor Johnson (5-of-8) and freshman Adrease Jackson (5-of-9) both chipped in a dozen. Sophomore James Foye came up big off the bench as well, posting career highs of nine points and eight rebounds, leading Dartmouth efforts on the glass.

After two sluggish performances at Penn and Princeton last weekend, the Big Green came out firing tonight, building a 14-5 lead thanks to 3-pointers by Wright and Foye to bookend the first five minutes.

The Lions roared right back with a 10-point run with a pair of triples of their own before Dartmouth scored the next nine points on two long balls and three-point play off a thunderous dunk by Wright.

Wright popped another 3-pointer to give the Green their largest lead of the half at 32-18 with 5 minutes until the intermission. When Columbia rattled off three consecutive buckets in the paint, Jackson provided a trey and Barry drove into the lane for two to keep the lead in double digits at the break, 39-28.

The lead would have been even larger if the Lions hadn’t crashed the glass, grabbing six offensive boards to score eight second-chance points while the Big Green hit 7-of-13 3-pointers (.538) and 15-of-26 (.577) from the floor overall. Columbia, meanwhile, was just 12-of-29 (.414) shooting and 3-of-11 (.273) from distance.

In the second half, Dartmouth briefly allowed the Lions to get within single digits before boosting its advantage to 19 points as the Big Green continuously answered nearly every Columbia score. Smith sank a long jumper with 12 minutes to play to get the Lions within 10 at 55-45 before freshman Aaryn Rai hit his first 3-pointer in six weeks, and Foye responded to a Smith triple with one of his own. That trifecta started a 10-1 Dartmouth spurt that was finished off by Wright with another 3-pointer and a finger roll to make it 68-49 with 8:25 to play.

Twice the Green matched Columbia scores to maintain that 19-point bulge, now with under seven minutes remaining, before a full-court Lions press started to whittle away at the lead. Quinton Adlesh, the leading 3-point shooter in the conference, drained two triples in a three-minute span, and the second of those long balls started a 10-0 run — ending on a Smith trey — to suddenly close the gap to four at 76-72 with 1:45 to play.

Wright calmly sank two free throws with 1:30 left, but Castlin cut the six-point lead in half with a three-point play. Dartmouth then turned the ball over on a shot-clock violation (though Wright hit a 3-pointer after the buzzer), but Columbia could not capitalize as Wright altered a layup and freshman Chris Knight grabbed the rebound. Johnson was then fouled with 19.1 seconds left, and the veteran sank both free throws for an 80-75 lead.

The Lions missed a pair of shots before Nate Hickman, who finished with 13 points, hit a meaningless 3-pointer from the corner as the horn sounded.

Columbia finished the game shooting 43.9 percent (29-of-66) and just 31.0 percent (9-of-29) behind the arc. The Lions had a 34-31 advantage on the boards and forced 15 turnovers while coughing the ball up 11 times, but just once after the break.

Dartmouth will wrap up its season with another opportunity to play the spoiler when it hosts Cornell (11-15, 5-8 Ivy) on Saturday at 7 p.m. The game will be streamed live on the Ivy League Network, now available on Apple TV, Roku and the ILN app for Android and Apple devices, featurning the call of Brett Franklin and Jill Koclanes.

Notes: The Big Green had not won a game when allowing 70 or more points all year … Dartmouth is 5-0 when leading at the half … with Barry’s first of three assists tonight, he became the first Big Green player with 100 helpers in a season since Flinder Boyd in 2002 … Wright moved into 21st place on Dartmouth’s all-time scoring list with 1,109 points. To reach the top 20, he will need 13 agains the Big Red to match Larry Lawrence ’80, while 18 more would allow him to reach former teammate Connor Boehm ’16 in 19th with 1,127 points … Jackson has started twice this year, both against Columbia, and averaged 18.0 points and 9.0 rebounds in those two games … Knight and Johnson each had five assists, a personal best for the former … the Lions would clinch that tournament berth with a win at Harvard tomorrow as they own tiebreakers over Princeton and Cornell, the other teams that are tied for fourth currently … Brown was eliminated from the race with its loss to Princeton tonight … Cornell needs both Princeton and Columbia to lose, and either beat Dartmouth or Brown beat Penn as a four-way tie for fourth would favor the Big Red … the Tigers would qualify for the tournament with a win over Yale and a Columbia loss at Harvard.
