BUFFALO, N.Y. — Sidney Crosby and the Pittsburgh Penguins didn’t need long to extend their mastery of the Buffalo Sabres.

Crosby’s first of five assists came 1:21 into the first period, and Pittsburgh pushed its season-high winning streak to seven games with a 6-1 win over Buffalo on Saturday night.

Crosby recorded a point against the Sabres for the 19th consecutive game, and the Penguins haven’t lost to Buffalo since April 2013, a span of five games.

Patric Hornqvist and Kris Letang had two goals each for the Penguins, and Evgeni Malkin and Roberto Bortuzzo also scored. Letang and Chris Kunitz both added two assists.
