PITTSBURGH — Jakob Chychrun scored twice during a second-period surge and the Washington Capitals raced past the Pittsburgh Penguins 8-3. Alexander Ovechkin was held without a goal to remain at 879 for his career, 15 away from tying Hall of Famer Wayne Gretzky’s all-time mark. The Capitals hardly needed the Russian superstar in their return from the 4 Nations Face-Off break as Washington improved to 13-1-6 in its last 20 games. Sidney Crosby scored his 18th of the season for Pittsburgh.
