BOSTON — Minutes after scoring the overtime goal that won Game 4 of the Stanley Cup Finals, Chicago defenseman Brent Seabrook uttered nine words that would be greeted with skull-imploding bewilderment in New York and Pittsburgh.

“It was nice to get a few past Tuukka,” Seabrook told NBC’s Pierre McGuire, referencing the stunning six goals — by six different players — that the Blackhawks scored against Boston Bruins goalie Tuukka Rask to even the series heading into Saturday night’s Game 5 in Chicago.

If Sidney Crosby, Evgeni Malkin or Rick Nash were watching, chances are their television screen now has a hole in the middle of it from a flying object. The Rangers rarely saw this Rask. The Penguins never saw this Rask. And, until Game 4, neither had Chicago.

Rask has been the best goalie in the playoffs with three shutouts. Statistically, even after Wednesday’s half-dozen hiccup, he still leads all playoff goalies in save percentage (94.1 percent) and goals against average (1.83) In the eight games before Wednesday night’s, he had allowed more than a single goal just once.

The notion that Chicago, or any team, could score six times against Rask, especially in Boston, where he had been seemingly impenetrable in the previous six games, seemed implausible. In the three games against the Rangers in Boston, Rask allowed a total of five goals. In two home games against Pittsburgh, one of which went into double overtime, he allowed one. Neither Crosby nor Malkin produced a point in the four-game series. Nash had 3 points over five games.

The six goals allowed by Rask were two more than his previous 2103 playoff high and matched his season worst, from a Jan. 31 game in Buffalo.

And his sudden vulnerability was stunningly versatile. The Blackhawks scored when they were short-handed. They scored on the power play, snapping a streak of 23 power plays without a goal. They scored on deflections. They scored on long shots. They scored on rebounds.

“Every goal is stoppable,” Rask said Thursday. “I don’t think there were any weak ones. They were mistakes that piled up and I wasn’t able to bail our guys out. Sometimes you do, sometimes you don’t.”

Rask added: “I just try not to let in six goals again. You let in six goals, that’s not something you look forward to repeating.”

The Blackhawks’ first goal, a short-handed tally by Michal Handzus in the first period, ended Rask’s shutout streak of 129 minutes 14 seconds — and his home shutout streak (he had blanked Pittsburgh in Game 4 and the Blackhawks in Game 3) at 193 minutes 16 seconds, a franchise record. There were three goals in the second, a fifth in the third and Seabrook’s winner with 11:09 left in the first overtime, a blast from the right point through a maze of Bruins and Blackhawks.

“I saw it at the last second,” Rask said. “Too late.”

He added: “I try to control everything and sometimes it doesn’t happen. I think everyone has to be better. It’s not rocket science. We were standing still and not doing the things we were supposed to do.”

That was Bruins coach Claude Julien’s take as well. He refused even to consider that his goalie might have had a bad game, saying: “I don’t evaluate the players publicly here. I look at our whole team and our whole team was average.”

That was immediately after the game, a game in which Zdeno Chara was on the ice for five of the Chicago goals and Dennis Seidenberg was on for four. That was after a game in which Chicago had eight different leads and Boston had none.

Game 5 is always critical in a best-of-seven series that is tied 2-2. In the Stanley Cup Finals, the winner of Game 5 has gone on to win the series 68.2 percent of the time. The Bruins, however, are one of four teams in the last six instances of a 2-2 tie who lost Game 5 and still won the Stanley Cup. So are the Blackhawks, who were in an identical position in 2010, tied with Philadelphia after four games. Chicago won Game 5 at home and closed out the Flyers in overtime in Game 6 on the road.
