Logan Thompson played well at the other end, and Rust's goal broke a shutout streak for him that was over 160 minutes at that point. The Penguins got 19 shots through to Thompson, but the Capitals blocked 18 other attempts and thwarted any second-chance opportunities, making it difficult for the Penguins to get too many grade-A looks.

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.

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