WASHINGTON (AP) - 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.


Thompson came up just short of becoming the first player in franchise history to record three shutouts in a row, when he allowed Bryan Rust to score midway through the third period. His shutout streak ended at 198 minutes, 22 seconds, the longest in the league this season and third in team history.


Brandon Duhaime sealed it with an empty-netter with 1:30 left. The Capitals are 7-0-3 in their past 10 games, picking up points despite not playing their best during this stretch.


The Penguins lost for an eighth time in 10 games. Pittsburgh goaltender Joel Blomqvist allowed three goals on 32 shots.Takeaways
Penguins: Even with defenseman Kris Letang back from his illness, they couldn’t keep the momentum going after beating Buffalo on Friday night and celebrating goaltender Alex Nedjelkovic’s empty-net goal.
