CHESTNUT HILL, Mass. — Sophomore Ian Sistare had a career-high 14 points with four 3-pointers — all in the first half — the last of which gave Dartmouth a 38-36 lead with a minute left in the first half. But Boston College (12-6) scored the final five points of the stanza, then embarked on a 23-4 run to start the second half, allowing the Eagles to pull away for an 86-72 victory over the Big Green (4-10) on Saturday afternoon at the Silvio O. Conte Forum.

All five BC starters scored in double figures, led by Ky Bowman with 19 points and Jerome Robinson with 17 more. Steffon Mitchell contributed a double-double with 10 points and rebounds as the Eagles shot a robust 55.9 percent (33-of-59) from the floor and 46.2 percent (12-of-26) from distance while dominating the glass, 35-26.

Sistare was a perfect 5-for-5 on his field goals but did not get a shot off after halftime. Freshman Aaryn Rai dropped 11 points for Dartmouth, which lost its fourth straight contest, and senior Taylor Johnson and sophomore Brendan Barry each chipped in 10.

The first half was a tight affair as Boston College only briefly had a lead as large as seven points. Sophomore Will Emery scored right out of the gate after winning the opening tap, and senior Miles Wright produced a three-point play to get the Green off to a good start. The Eagles countered by going inside again and again, collecting a pair of dunks with Nic Popovic (who had 14 points and eight rebounds) providing three of their first five baskets for an early 10-6 lead.

“Boston College simply made some very good individual plays to start the second half and that kind of zapped our energy a little bit,” said Big Green head coach David McLaughlin. “The most important thing we can have for 40 minutes is a collective passion, level of discipline and attention to detail. But when we face some adversity in a game, we are losing those qualities. We need to learn together how to make those qualities stronger when we face that adversity.”

Sistare drilled his first long ball of the afternoon to keep Dartmouth within one at 12-11 before BC got its outside game going on triples by Robinson and Vin Baker Jr. for that brief seven-point edge, 18-11. Sistare then drove for a layup and drained another trey before Johnson hit a long jumper to knot the score at 18.

The next six points went to the Eagles when a long-range shooting contest broke out. Rai hit one from behind the arc, only to be answered by Robinson. Then Sistare and Wright went back-to-back to tie the game at 27, then freshman Adrease Jackson gathered an offensive rebound and scored for a 29-27 lead.

Robinson was fouled in the act of shooting a 3-pointer, and he converted all three free throws, and the teams traded a total of five bombs, the last one by Sistare for a 38-36 lead with a minute to the intermission. But Mitchell hit a tough shot in the paint, and after a shot-clock violation, Bowman rained down a 3-pointer at the buzzer for his first points of the game and a 41-38 Boston College lead.

Both teams hit half of their field goals (14-of-28) in the first half, while Dartmouth was a scintillating 8-of-13 (.615) from downtown compared to a mere 6-of-13 (.462) for the Eagles. But BC was 7-of-11 at the charity stripe with the Big Green just 2-of-3 to make up the difference.

The momentum the Eagles built at the end of the first half continued into the second stanza as Bowman heated up with three points the hard way and the easy way for a sudden nine-point advantage. His next trifecta boosted the BC lead to 14 at 54-40, and after a Rai bucket, Bowman popped another from behind the arc. Jordan Chatman (15 points) slammed home a dunk, Robinson hit his fourth 3-pointer and Bowman stole a pass and dunked the ball at the other end to cap the seven-minute, 23-4 outburst, leaving Boston College with a comfortable 64-42 lead.

The difference did not dip below 18 until the final minute of the game as both teams cleared their bench. Joseph Cook, a fifth-year football player who joined the team last month to help with depth, ended the game with a putback for his first career statistics.

The Eagles shot 61.3 percent (19-of-31) over the final 20 minutes and went 6-of-13 from long range in each half of play. Bowman was 7-of-14 overall and 4-of-8 outside the arc, plus added six assists without a turnover.

Dartmouth’s accuracy from the perimeter failed in the second half, hitting just 1-of-10 3-pointers, but the Big Green were 12-of-20 inside the arc and finished the game shooting 46.6 percent (27-of-58), exactly what they were shooting from the floor entering the game.

This concluded the Big Green’s non-conference schedule as they return home next Saturday to host Harvard (6-10, 1-0 Ivy) at 7 p.m. The game will be televised on Eleven Sports Network and streamed live on the Ivy League Network — now available on Apple TV, Roku and the ILN app for Android and Apple devices — with Bob Lipman and former Dartmouth coach Dave Faucher calling the action. Big Green fans can also listen over the airwaves to Brett Franklin and Jill Glessner on KOOL FM (106.7 and 96.3) in the Upper Valley.

Notes: Dartmouth has had four players score in double figures in a game five times this year, but has lost all five contests … Sistare is 7-for-7 on his 3-pointers in two games against ACC teams this year and 2-for-14 against everyone else … Rai has scored in double figures twice this season, both coming against the ACC opponents (Notre Dame and BC).
