Jonathan Toews had three goals and an assist, Corey Crawford made 14 saves in relief of an ineffective Nikolai Khabibulin and the Blackhawks beat the Ottawa Senators 6-5 on Tuesday night. Andrew Shaw scored twice and Marian Hossa had a goal and two assists for the Blackhawks, who trailed 4-2 with 8:46 left in the second period. It was Hossa’s 100th goal with the Hawks and No. 439 for his career.The Senators scored three times in a span of four shots in the second, but were unable to hold off the suddenly high-scoring Blackhawks. Kyle Turris and Milan Michalek each had a goal and an assist in Ottawa’s fourth loss in five games. Toews sparked the rally when he tested former Hawk Craig Anderson with 5 1/2 minutes left in the second, and his first attempt popped over the goal. The captain then skated to the back of the net and slammed in a wraparound for his fifth goal of the season. The Blackhawks kept coming in the third period, and Toews tied it at 4 when he finished off a perfect pass from Johnny Oduya at 1:20. He completed his third career hat trick when he pushed a rebound into an empty net midway through the period for a 5-4 Hawk lead. Shaw and Ottawa’s Zack Smith exchanged goals down the stretch, and the Blackhawks held on for their second victory in as many nights. The defending Stanley Cup champions beat Minnesota 5-1 on Monday. Clarke MacArthur had two assists for the Senators, and Anderson finished with 34 saves. MacArthur missed Ottawa’s previous game with what the team called a minor injury.Ottawa appeared to be in control after one dizzying stretch in the second. MacArthur sparked the scoring spree when he charged toward the net from the right side, setting up Turris’ power-play score from in-close that gave Ottawa a 2-1 lead at 6:51. Hossa responded 50 seconds later, converting a nice pass from Toews, but Senators were just getting started against the ineffective Khabibulin.Joe Corvo‘s long slap shot whistled by teammate Bobby Ryan and into the net for his first goal of the season. Then Mika Zibanejad skated past sliding Blackhawks defenseman Duncan Keith and beat Khabibulin to make it 4-2 at 11:14.That was enough for Blackhawks coach Joel Quenneville, who replaced Khabibulin with regular starter Crawford. Khabibulin made 18 saves and has allowed 10 goals while facing 47 shots in his past two games. Crawford’s entry prompted a big cheer from the crowd, and the Blackhawks seemed to feed off the switch.Sharp had two assists and Toews extended his points streak to five games. Toews has five goals and four assists during the stretch.

NOTES—Michal Handzus was among the Blackhawks’ scratches, and Quenneville said he probably would remain out through this weekend. The 36-year-old Handzus hasn’t played since a 6-5 overtime loss at Tampa Bay on Thursday. … The Blackhawks will visit President Barack Obama at the White House on Monday to celebrate their second Stanley Cup title in four seasons. “I think it will be one more reflection of a pretty special year for us all,” Quenneville said. … The Hawks have one power-play goal in each of the past six games.
