New York Rangers at Pittsburgh Penguins

Mantha and Acciari score twice, Penguins running winning streak to 6 by holding off the Rangers 6-5

Mantha and Acciari beat Jonathan Quick twice in a span of just over three minutes early in the first period to give the Penguins an early cushion. Mantha made it 3-0 with an easy tap-in in the second period. Acciari and Rickard Rakell scored 20 seconds apart early in the third to push Pittsburgh's advantage to 5-1 on a night the franchise celebrated the 10th anniversary of the 2016 club that won the Stanley Cup.

Erik Karlsson became the 12th defenseman in NHL history to reach 700 career assists when he picked up the secondary helper on Rakell's 10th goal of the season 1:20 into the final period. The other 11 defensemen to reach the 700-assist plateau are in the Hall of Fame.

Stuart Skinner improved to 8-1 in his last nine starts but nearly let a four-goal third period get away.

Alex Lafreniere scored twice for the Rangers. Vincent Trocheck, Vladislav Gavrikov and Will Cuylle all scored during a late rally, but it wasn't enough for the Rangers to fall to 2-10 since goaltender Igor Shesterkin was lost indefinitely with a lower-body injury.

Until the late surge, New York coach Mike Sullivan — who guided the Penguins to consecutive Stanley Cups in 2016 and 2017 during a decade-long run as head coach before trading Pittsburgh for New York last summer — watched his team spend most of the afternoon putting up little fight against the surprising Penguins.

Pittsburgh moved into second place by itself in the Metropolitan Division with the victory despite being without veteran defenseman Kris Letang, who will miss at least a month with a fractured left foot sustained in a win over Chicago on Thursday. The 20-year veteran was wearing a protective boot on the foot during a pregame ceremony honoring the 2016 club.

Up next Rangers: Off until Thursday night, when they host Carolina in the final game before the Olympic break.

Penguins: Host Ottawa on Monday night.
