Alex Park drove Dartmouth 91 yards for a touchdown with 1:09 remaining as the Big Green edged Columbia 21-16 Saturday.
After an incompletion. Park completed three straight passes to Ryan McManus, ran for 13 yards himself, then hit McManus for a 15-yarder that put the Big Green (4-2, 2-1 Ivy League) at the 15 of the Lions (1-5, 0-3).
Park's 7-yard completion to Victor Williams, with roughing the passer tacked on, moved the ball to the 4 with 1:16 left. Following a Dartmouth procedure penalty, Park found Dean Bakes for the go-ahead score.
A Dartmouth celebration penalty and a kickoff out of bounds enabled Columbia to get the ball back at midfield, but Sean Brackett's fourth-down pass from the 40 was intercepted by Stephen Dazzo.
Columbia lost 24-20 to Pennsylvania last week on a touchdown in the final minute.
Park completed 20 of 28 passes for 197 yards.
