Early in the first period of Sunday night’s game, Blackhawks goaltender Corey Crawford found himself badly out of position as the puck fell to Blue Jackets center Derick Brassard in the high slot. The net was wide open, but Brassard’s hurried shot somehow sailed high — a nervous moment and a big break for Crawford, who worried that his timing might be a bit off after 12 days out with an injury.

It was the only break he’d need.

Crawford had 28 saves for his second shutout in three starts as the Hawks made Andrew Shaw’s second-period goal stand and extended their record season-opening point streak to 18 with a taut 1-0 victory over Columbus.

Crawford hadn’t played since a Feb. 12 overtime loss against Anaheim. But it was like he never left.

“Seems like things haven’t changed,” he said. “Everyone’s playing hard, making the right plays, not turning pucks over, and guys are coming back to help out our ‘D.’ Our ‘D’ has been so good this year, blocking shots and [getting] sticks in lanes. It’s just another solid victory for us.”

Indeed, the Hawks blocked 16 shots, with Niklas Hjalmarsson leading the way with six. Hjalmarsson also was highly effective in front of Crawford, clearing pucks out of the crease. Duncan Keith and Michal Rozsival blocked three shots apiece.

“It’s obviously big for the goalies to have some guys that have good sticks in front to clear rebounds and be in shooting lanes, and I think we did that good today,” Hjalmarsson said. “Obviously — we had a shutout.”

Shaw got the lone goal with 1:27 left in the second period, chipping in a beautiful backhanded centering pass from Bryan Bickell after Johnny Oduya saved the puck at the point and cycled it down. Shaw later took a spear in a most uncomfortable place from Blue Jackets defenseman James Wisniewski — a retaliation for a cross-check Shaw delivered — but stayed in the game after a brief stint on the bench.

“I gave him a holler, and he put it in the perfect area,” Shaw said of Bickell’s pass.

The Hawks sit at a gaudy 15-0-3. But perhaps just as impressive, they’re 9-0-3 in one-goal games — including four straight wins in such a manner.
