HANOVER, N.H. -- Dominick Pierre accounted for 230 yards of offense and the go-ahead touchdown to help Dartmouth outlast Yale 20-13 in an Ivy League matchup Saturday.

Trailing 13-6 midway through the third quarter, the Big Green (2-2, 1-1) fired back as Dalyn Williams found Bo Patterson for a 32-yard touchdown.

Pierre scored from six yards out with 10 minutes remaining in the fourth quarter to take the lead.

The Bulldogs (3-1, 1-1) got the ball with three minutes remaining, but a Tyler Varga fumble cut the drive short. A Yale facemask penalty on Dartmouth's fourth-and-two attempt denied a potential late rally, handing them their first loss.

Pierre was a workhorse for Dartmouth, amassing 167 yards on 37 carries and adding four receptions for 63 yards.

Williams went 14-of-30 for 188 yards with two touchdowns and an interception.

Henry Furman finished 15-for-32 with 144 yards and an interception for the Bulldogs.
