The Penguins and Capitals renewed arguably the highest-profile rivalry of the salary-cap era on Saturday night.

WASHINGTON -- Aliaksei Protas and Pierre-Luc Dubois each had a goal and an assist, and the Washington Capitals extended their point streak to 10 games with a 4-1 win against the Pittsburgh Penguins at Capital One Arena on Saturday.

Jakob Chychrun, Aliaksei Protas and Pierre-Luc Dubois scored, Logan Thompson made 18 saves and the NHL-leading Washington Capitals beat the Pittsburgh Penguins 4-1 on Saturday night for their fourth consecutive victory.

With the Penguins leading the Sabres 4-2 and Buffalo's goalie Ukko-Pekka Luukkonen at the bench, the Sabres would put the puck into the corner and the puck would come to Nedeljkovic. With that goal, Nedeljkovic would become just the second goalie in the Penguins' history to score a goal.

BUFFALO -- Alex Nedeljkovic had a goal and an assist and made 40 saves for the Pittsburgh Penguins in a 5-2 win against the Buffalo Sabres at KeyBank Center on Friday.

Pittsburgh Penguins goaltender Alex Nedeljkovic had an excellent night between the pipes on Friday night. He stopped 40 of the 42 shots he faced in a 5-2 win over the Buffalo Sabres, but he also made NHL history by generating some offense.
