Marcus Kruger, Brent Seabrook, Andreas Martinsen, Brandon Saad each had a goal and an assist for Chicago, which rebounded after blowing 2-0 and 3-2 leads to win for just the second time in 12 contests. Alex DeBrincat scored a power-play goal.
Toews became the 16th active player to reach 700 career points with the same franchise. He assisted on Saad’s empty-netter for his 701st point.
Kruger snapped a 3-all tie when he beat Casey DeSmith from the front of the crease 3:49 into the third period. Martinsen set up Kruger’s fourth goal of the season with a centering pass from below the goal line.
Toews also had an empty-netter before Saad made it 6-3 with his ninth goal at 19:39.
Bryan Rust scored three times for Pittsburgh in his second career hat trick. The 26-year-old forward, who entered with one goal in 29 games this season, missed on several other prime chances.
Corey Crawford made 40 saves for Chicago. DeSmith blocked 23 shots in his sixth straight start and 10th in the last 12 games.
Matt Murray, who started the season as Pittsburgh’s No. 1 goalie, was activated from injured reserve and served as DeSmith’s backup. Murray missed 11 games with a lower-body injury.
The Blackhawks shook up their roster on Wednesday morning by recalling forward Dylan Sikura and defenseman Carl Dahlstrom from Rockford of the AHL and sending forward Alexandre Fortin to the minors. Sikura and Dahlstrom played.
Chicago is 4-12-2 under coach Jeremy Colliton, who replaced Joel Quenneville on Nov. 6.
The Blackhawks opened the scoring for the first time since Nov. 18 and led 2-1 after one period. Opponents had scored first in Chicago’s last 11 games, outscoring the Blackhawks 25-5 in the first period during that span.
Martinsen skated across the crease and was credited with his first goal of the season on a deflection of Dahlstrom’s shot at 14:14. The goal capped a flurry around the Pittsburgh net after Kruger fired a shot off the crossbar and DeSmith lost his stick.
Seabrook put Chicago ahead 2-0 3:37 later when he fired a shot from the right point over DeSmith’s glove.
Rust cut it to 2-1 with 1:20 left in the first when he skated from the left corner and beat Crawford on the glove side.
Rust’s second goal, at 5:46 of the second, tied it at 2. After Seabrook’s turnover, Crawford made a pad save on Derek Grant’s drive from the slot, but Rust buried the rebound.
DeBrincat’s power-play goal with 4:32 left in the period regained the lead for Chicago. After taking Patrick Kane’s feed, DeBrincat skated around Olli Maatta and beat DeSmith on the stick side with a shot just under the crossbar.
Rust tied it at 3 with 56.8 seconds left when his cross-ice pass from the left side of the net deflected off Seabrook’s stick and past Crawford.
