Apparently, two games is the Blackhawks' limit when it comes to losing streaks. For the third time this season, the Hawks avoided dropping more than two in a row as they defeated the Flames 2-0 on Tuesday night at the United Center. Nick Leddy and Brent Seabrook scored to provide the offense and goaltender Ray Emery continued his stellar play against Calgary this season to remain unbeaten with a 12-0-0 record. The consistent Hawks improved to 25-4-3 this season and helped erase the memory of two straight losses after leading in the third period of both games. Avoiding prolonged skids has been the Hawks' trademark this year and it has helped them record the most points in the NHL with 53. "The things that we weren't great at the (last) couple of games we lost we corrected and it showed," said Leddy, who opened the scoring in the first when his shot from the left dot slid through Flames goaltender Miikka Kiprusoff's pads. "We played a great game and Ray played great again." Emery made 16 saves to shut down the Flames for the second time this season. In the first meeting between the teams this season, the veteran made a career-high 45 saves in a 3-2 shootout victory Feb. 2 in Calgary. Tuesday night's triumph extended Emery's NHL record for starting the season without a loss to 12. The shutout was Emery's first this season and 12th of his career. "We got a lead early on and continued to apply pressure," Emery said. "We really didn't give much up again so it was a great night defensively. "They didn't really have in-tight chances and whenever you get a shot you can see, it's a routine save. It's always good to get to put a zero on the board but I'm just glad to get a win."
