PITTSBURGH (AP) — Egor Chinakhov and Anthony Mantha scored on rushes in a 31-second span in Pittsburgh’s four-goal second period, helping the Penguins beat the Chicago Blackhawks 6-2 on Thursday night for their fifth straight victory. Connor Dewar scored twice, Ben Kindel and Ryan Shea added goals, and Arturs Silovs made 17 saves. Mantha, Shea and Noel Acciari each had two assists. The Penguins had been off since sweeping a four-game trip with a victory over Vancouver on Sunday, with forward Bryan Rust starting a three-game suspension for a check to Canucks forward Brock Boeser’s head. Connor Murphy and Connor Bedard scored for Chicago, and Soderblom stopped 38 shots in the first game of a back-to-back. The Blackhawks have lost four straight.
