Guentzel wins it in OT as Pens, Caps clinch playoffs
The result, combined with the New York Islanders' regulation win over the New York Rangers, ensures both teams will be among the Eastern Division's four playoff teams. Kasperi Kapanen scored his ninth and 10th goals of the season, Frederick Gaudreau added a goal in his return from injury and Zach Aston-Reese also scored for the Penguins, who have now won five of their seven meetings with the Capitals. Colton Sceviour and Jared McCann each had two assists for the Penguins.
