Penguins 3, Capitals 2:

Erik Karlsson scored on a bad-angle shot with 4:11 left in the third period, sending the Ottawa Senators to a 2-1 victory over the New York Rangers in the opener of their second-round playoff series on Thursday night.

The Senators captain beat fellow Swede Henrik Lund- qvist from just above the goal line. The shot pinged off Rangers center Derek Stepan before going into the net.

It was Karlsson’s first goal and seventh point of the playoffs. The 26-year-old defen- seman, who has been playing with a foot injury, also logged more than 28 minutes in the win.

Craig Anderson stopped 33 shots and Ryan Dzingel scored for Ottawa, which eliminated Boston in six games in the first round.

The 35-year-old Lundqvist was terrific, especially early on. He made 21 saves in the first, including a pair of stops on Mark Stone during a flurry around the net on Ottawa’s first power play.

Game 2 is Saturday. Sidney Crosby scored two goals in 52 seconds, Nick Bonino had the winner in the third period, and the Pittsburgh Penguins beat the Washington Capitals 3-2 in Game 1 of their second-round playoff series Thursday night.

In a high-profile showdown of Crosby and Alex Ovechkin, Washington’s captain also scored and Evgeny Kuznetsov had the goal that tied it in the third. But Marc-Andre Fleury made 15 of his 32 saves in the third period to help Pittsburgh to the win.
