CHICAGO (AP) -- The Blackhawks keep finding ways to rally for wins. Chicago nearly ran out of time trying to come from behind Saturday night.
Robert Lang deflected in rookie Jonathan Toews' shot with 1.5 seconds left in the third period to tie it at 1, ruining Tobias Stephan's shutout bid in his first NHL game. Lang connected on a 5-on-3 power play, with Chicago goalie Patrick Lalime pulled for an extra attacker.
Toews' shot changed direction after hitting Lang in the upper body.
"We probably scored one that shouldn't have gone in," Lang said. "It was a shot that goes wide, but it hits you and goes in. I'm happy to take any of those."
Chicago (3-2) has come from behind in each of its wins.
Williams beat Stephan on a high shot from 40 feet out, with Toews cutting across the crease. Stephan was screened on the shot.
"He (Stephan) made a couple of big saves early on," Toews said. "That gave him confidence.
"Bottom line: When you run into a hot goalie like that, we've got to stick with it. That's what we did tonight."
Chicago held a 19-14 advantage in shots through two periods, but trailed 1-0 thanks to a power-play goal by Dallas' Brenden Morrow late in the first.
Stephan blocked several screened attempts through opening 40 minutes, but didn't face many rebounds or sustained pressure until the third period, when the Blackhawks outshot the Stars 20-4.
Meanwhile, Lalime made 17 saves in his first start this season.
It looked like Stephan would be able to hang on to his shutout. But a holding penalty to Dallas' Jeff Halpern with 45 seconds left in the third and a hooking call to Mike Modano with 27 second remaining created the 5-on-3 Blackhawks advantage.
"It was really frustrating to be so close, only 1.5 seconds," Stephan said. "It was a tough loss and very disappointing."
Dallas (2-2-2) lost in overtime for the second time in two nights.
"I feel bad for him," Stars coach Dave Tippett said. "He played a helluva game. He was just under so much pressure."
Morrow's power-play goal with 6:12 left in the first period seemed like it might be enough for Stephan and the Stars. Morrow knocked in a loose rebound from the crease after Lalime had blocked Niklas Hagman's attempt from the left side of the net.
"We got off to a great start," Morrow said. "We were playing with fire."
Just over six minutes into the third, Stephan made a glove save on Lang's quick shot from the slot. He was sharp during several flurries later in the period, until Lang finally managed to tie it.
