Unlike the 22,110 fans in the United Center, Blackhawks goaltender Corey Crawford never wondered how at least one of the 29 shots in overtime Wednesday night — some fired point blank and some ricocheting off the post — did not slip past him.

"No," he said. "My job is to keep it out. I don't want to start doubting myself in OT."

Nobody in Chicago has any misgivings about Crawford now.

He saved 51 of 54 Bruins' shots in the Hawks' 4-3 triple-overtime victory in Game 1 of the Stanley Cup Final, which ended at midnight.

He gave up the first two goals of the game but buckled down and received some critical help in the crease from Hawks defensemen.

The game required the most concentration of any in his career, which goes back to 2005 with the Hawks.

"I felt a little more zoned in," he said. "You just focus on everything. Make sure the next one doesn't go in."

He deflected some head-on shots in the first overtime, saw a puck bounce off the post and watched Kaspars Daugavins' near wide-open shot in the third overtime inexplicably miss the net.

He also helped kill a critical penalty between the first and second overtimes.
