HANOVER, N.H. -- The calendar reads Friday the 13th, and that certainly made for a strange game for the Cornell men's hockey team. A bizarre ending involving a disputed overtime game-winner gave Dartmouth a 5-4 victory at Thompson Arena in Hanover, N.H.

Dartmouth scored the controversial game-winner as time was expiring on a penalty to Keir Ross, who had just stepped on the ice when Gaudet tipped home a shot from Doug Jones from the hash marks. Referee Alex Dell, stationed behind the goal, immediately waved off the goal, but ultimately was overruled by the trail referee, Bryan Hicks, and the goal stood just 1:05 into the overtime period.

Joe Devin and Colin Greening both had a goal and an assist for the Big Red, while Brendon Nash added a pair of assists. Evan Barlow and Mike Devin both scored goals for Cornell, while Riley Nash and Justin Krueger each added an assist. For Dartmouth, Gaudet scored a pair of goals, while Rob Pritchard, Connor Shields and Jim Gaudet each had a goal.

In goal for Cornell, Ben Scrivens had 26 saves in picking up his fifth loss of the season. Jody O'Neill stopped 24 Cornell shots in taking the victory, his 13th. On the night, the Big Red went 1-for-5 on the power play, while Dartmouth converted one of its six man-advantage opportunities.

Cornell got on the board early with Joe Devin's eighth goal of the season. Colin Greening worked the puck back to the point where Brendon Nash one-timed a shot that deflected off the stick of a Dartmouth defenseman and popped up into the air. The puck was gloved down at the far post by Devin, who calmly jammed the puck past the diving out-stretched arm of O'Neill with just 2:26 gone in the game.

Cornell got the second goal of the game at the 5:15 mark of the game, as Gallagher intercepted a pass at the Cornell blue line and worked the puck toward Joe Devin in the neutral zone. Devin sent a pass between his legs to the streaking Greening, who skated in alone and snapped off a shot from between the circles that beat O'Neill through the legs and trickled across the goal line.

On the first power play of the night, the Big Red nearly made it 3-0 when Evan Barlow hit Gallagher on the back post with a sharp pass, but the junior couldn't quite get a stick on the puck before O'Neill recovered to the weak side, ultimately stuffing the shot attempt with his right leg. Later in the period with the two teams back at full strength, Riley Nash broke in alone behind the Dartmouth defense, but O'Neill was there for the save, again with the right leg.

Dartmouth cut into the lead at the 13:00 mark of the first period, as a puck around the boards behind Scrivens was sent back in front of the goal mouth by Josh Gillam, and Rob Pritchard was alone at the top of the crease to knock the puck in over the glove hand of Scrivens, making the margin 2-1.

With 32 seconds gone in the second period, Dartmouth nearly knotted the score at two, but Scrivens recovered to make a diving stop on the Big Green's Connor Shields with a pile in front of the Cornell goal.

Midway through the second period, the Big Green tied the score on an unlucky bounce. Dartmouth defenseman Jim Gaudet lofted the puck into the Cornell zone, and Scrivens came out to play it with his stick. Unfortunately for the junior goaltender, the puck glanced off his stick the wrong way and was re-directed into the Cornell goal, making the score 2-2.

Cornell took the lead again with 3:48 to play in the second period. Brendon Nash started the play with a shot from the point that O'Neill kicked into the corner, where it was collected by Riley Nash. Nash skated in along the goal line and flipped a shot that O'Neill stopped with his leg, but the rebound lay in the crease long enough for Barlow to skate in and jam the puck underneath the freshman netminder and into the goal.

Dartmouth knotted the score again with 2:23 to play in the second period, this time taking advantage of a power-play generated on an interference call on Blake Gallagher. Doug Jones sent the puck toward the goal, where Joe Gaudet tipped the puck in on the glove side of Scrivens to knot the score at three.

Just over a minute later, the Big Green took the lead, capitalizing on a turnover in the Cornell end. Dartmouth's Shields jammed home a rebound off a Scott Fleming shot, giving Dartmouth its first lead of the night, a lead that it would carry into the second intermission.

Cornell opened up the third period with three straight penalties on Dartmouth, and on the third one, the Big Red finally knotted the score on a frozen rope of a shot from the center point from Mike Devin after taking a feed from Justin Krueger off the faceoff circle to the right of O'Neill.

Midway through the third period, Scrivens nearly had his second freak goal of the night, as a dump-in off the glass on the half-wall to his left kicked off a support post and caromed toward the goal, with Scrivens moving to play the puck behind the goal. He was fortunately able to turn and make a diving stab with his stick to prevent the puck from going into the gaping net.

Cornell returns to action on Saturday, traveling to Harvard for a meeting against the Crimson. Saturday's game begins at 7 p.m. and will be televised nationally on CBS College Sports, which can be seen in the Ithaca area on Time Warner Cable's Sports Tier, channel 244.
