BOSTON — Jordan Binnington stopped 38 shots, Ryan O’Reilly and David Perron scored and the Blues took a controversial 2-1 victory over the Bruins on Thursday night for a 3-2 lead in the Stanley Cup Final.

The Blues have won two straight since a 7-2 loss at home and return to St. Louis with a chance to clinch the first NHL title in franchise history. Game 6 is Sunday night and the Blues are riding a red-hot goalie.

“Unbelievable. [Binnington] won one for us,” defenseman Colton Parayko said.

Tuukka Rask stopped 19 shots and Jake DeBrusk scored for Boston. The Bruins were lifted by the return of captain Zdeno Chara, who left Game 4 dripping blood after taking a deflected puck off his face. He wore a full-face shield on his helmet, but was unable to provide more than an emotional boost.

O’Reilly scored in the opening minute of the second period, and it was still 1-0 midway through the third when the referees disregarded a leg sweep by Tyler Bozak that knocked Noel Acciari out of the game. Perron followed with a shot that banked off Rask’s pad and into the net. The fans responded with a vulgar chant and a shower of rally towels.

“It’s blatant,” Bruins coach Bruce Cassidy said of Bozak’s hit. “It’s the National Hockey League’s getting a black-eye with their officiating in these playoffs, and there’s another one that’s going to be talked about.”

Boston cut the deficit to one on a delayed penalty with about 6 ¹/₂ minutes left. Torey Krug took a high stick to the face, but he played on, straightened his helmet and dished the puck to DeBrusk for a one-timer.
