HANOVER, N.H. (AP) — Taylor Johnson scored 18 points and made a layup with a second left in overtime, and Dartmouth beat Columbia 80-79 on Saturday night.

Columbia jumped out on 10-6 spurt in the extra period before Evan Boudreaux hit a 3-pointer from the corner to pull Dartmouth to 79-78 with 12.5 left. Quinton Adlesh missed a pair of free throws on the Lions' next possession. Johnson grabbed the rebound, ran the floor and made a right-handed scoop shot off the glass while stumbling for the game-winner. Columbia's inbounds pass to midcourt was knocked away to end it.

Johnson made a deep 3-poiner at the end of regulation, but a review ruled it late to force overtime tied at 69.

Guilien Smith led Dartmouth (6-17, 3-7 Ivy League) with 23 points. Boudreaux had 12 points and 10 rebounds for his 12th double-double of the season.

Luke Petrasek had 18 points for Columbia (10-13, 4-6), which trailed 60-48 midway through the second half.
