Marian Hossa scored two power-play goals less than 3 minutes apart to ignite a five-goal outburst by Chicago in the second period, and the Blackhawks rolled to a 6-3 win over the San Jose Sharks on Monday night.
Jonathan Toews and Patrick Kane each had a goal and an assist in the second as Chicago snapped an 0-1-2 streak and moved into fourth place in the Western Conference with 84 points.
Kane's goal was the 100th of his career.
Viktor Stalberg and Niklas Hjalmarsson also scored, and Patrick Sharp had a career-high four assists for the Blackhawks, who improved to 11-2-4 in their last 17 games.
Joe Pavelski, Joe Thornton and Logan Couture scored for the Sharks, who lost in regulation for just the fourth time in their last 25 games.
Hossa's goals were his 20th and 21st, giving him 20 or more in 11 straight seasons. He has points in 10 of his last 11 games, with nine goals and six assists in that span.
Toews now has 71 points, a career high for the fourth-year forward. He has recorded points in 12 of his last 13 games, with 11 goals and 10 assists during the run.
Chicago rookie Corey Crawford made 33 saves in his 15th straight start.
San Jose's Antti Niemi made his 25th consecutive start, but was replaced by Antero Niittymaki at 7:25 of the second after allowing four goals on 18 shots, and three goals on the last five he faced. Niittymaki stopped 14 of 16 shots.
Pavelski opened the scoring 2:20 in with a 5-on-3 power-play goal from the right circle, but Stalberg evened it midway through the first when he batted in a rebound of Chris Campoli's shot from mid-air.
Thornton put the Sharks ahead 2-1 with 1:24 left in the first. Campoli and Troy Brouwer both converged on San Jose's Patrick Marleau, and Marleau dished to Thornton, who broke in alone down the slot.
The Blackhawks then reeled off four straight goals, and five overall in the second, to take a 6-3 lead after 40 minutes.
Chicago launched its onslaught when Hossa scored back-to-back power-play goals and Toews added an even-strength score in a 4:11 span early in the second.
Hossa tied it 2-all 3:14 into the period when he cut to the edge of the crease and converted Sharp's feed. Just under 3 minutes later, Hossa put the Blackhawks ahead 3-2 on a low shot from the slot.
Toews finished a 2-on-1 with Kane by shooting himself and beating Niemi through the five-hole at 7:25 to make it 4-2. That prompted San Jose coach Todd McLellan to send in Niittymaki.
Chicago kept up the pressure and took a 5-2 lead with 5:31 left in the period when Hjalmarsson fired in a shot through traffic from the slot.
Couture popped in a rebound off Crawford's pad with 2:36 left in the second to cut it to 5-3, but Kane replied just 22 second later when he was left open in the slot.
The Sharks didn't mount a serious threat in the scoreless third.
