The Portland Winterhawks twice erased one-goal deficits in the third period on Sunday, but the Everett Silvertips prevailed 4-3 in a shootout in front of 4,266 fans at Memorial Coliseum.
The result left the two rivals tied atop the Western Hockey League's U.S. Division with 56 points.
Portland (26-13-1-3) has played two fewer games than Everett (27-16-1-1).
Skyler McKenzie scored two goals and Kieffer Bellows had a goal and an assist for the Winterhawks.
Everett's Matt Fonteyne won it in the fourth round of the shootout after both teams scored on one of their first three shootout attempts.
Portland managed to score three times against Everett goalie Carter Hart, who recently led Canada to the gold medal at the World Juniors.
"I was glad how we came back against a World Junior goalie. It's sometimes tough to come back on guys like that," Winterhawks VP/GM/coach Mike Johnston said.
McKenzie, who has a team-best 33 goals on the season, gave Portland a 1-0 lead 13:48 into the game. He found a rebound with Portland on a power play and tucked it in before Everett goalie Carter Hart could react.
Fonteyne tied the game 13:33 into the second period on a power play, and Everett took a 2-1 lead moments later on a rebound finish off the rush by Martin Fasko-Rudas.
Bellows tied the score early in the third period, taking an up-ice pass from Dennis Cholowski, skating up the right wing and ripping a shot past Hart.
Everett reclaimed the lead 7:18 into the third period, seconds into a power-play chance as Connor Dewar put home a back-door chance from Patrick Bajkov.
Portland's tying goal was a beauty as McKenzie re-directed a pass from Bellows past Hart with 4:34 left.
Moments later, Portland went on a four-minute power play, but Everett effectively killed it.
After the scoreless three-on-three overtime, both teams scored once in the three-round shootout, Bajkov beating Cole Kehler in the second round and Bellows making a nifty move to force a fourth round by scoring for Portland in the third round.
Everett had a 42-26 edge in shoots and was 2 for 6 on the power play. Portland was 1 for 6 on the power play.
It was the third game in as many nights, and the fourth in six days for Portland. It was only the third game in seven days for Everett.
The Winterhawks have another busy week, playing home games against Victoria on Wednesday and Swift Current on Friday, visiting Vancouver on Saturday then coming back for a Sunday home game against Brandon.
