CHICAGO — Dustin Byfuglien has emerged as a force for the Chicago Blackhawks and now he is taking his game to the highest level. He and his teammates are headed to the Stanley Cup finals.

Byfuglien scored his third go-ahead goal of the Western Conference finals, converting on a third-period power play as Chicago rallied to beat the San Jose Sharks 4-2 on Sunday and complete a four-game sweep that sent the Blackhawks to the NHL finals for the first time since 1992.

“Seems like he likes the spotlight. He likes being the hero. He steps up in big time,” teammate Patrick Sharp said. “He told me before the third period he was going to be the guy to go get it. True to his word, he got it.”

Chicago will play either Montreal or Philadelphia and be in search of its first NHL title since 1961, more than two decades before many of the current players were born.

“It’s an honor to be going to the Stanley Cup. We beat a very good team over there. It wasn’t easy,” Byfuglien said.

The 257-pound Byfuglien was parked in front of the net with 7 seconds left on the power play. He took a nice pass from Patrick Kane and knocked the puck past Evgeni Nabokov to give the Blackhawks a 3-2 lead at 14:05 of the final period.

“I got my stick open in front of the net, and Kaner game me a nice little feed,” Byfuglien said.

Moving Byfuglien to the top line with Kane and captain Jonathan Toews was one of coach Joel Quenneville’s best adjustments.

Kris Versteeg added an empty-net goal with 42 seconds left, and the red-clad fans at the United Center erupted, littering the ice with souvenir towels.
