Defensemen Duncan Keith and Niklas Hjalmarsson scored 1:04 apart in the second period, and the Chicago Blackhawks beat the Los Angeles Kings 4-1 on Monday.

Marian Hossa added a goal and an assist as the Blackhawks won their second straight game in as many nights and pulled within a point of the second-place Blues in the Central Division. Chicago plays St. Louis twice in its final six games.

Jake Muzzin scored for the defending champion Kings, who dropped their second straight in the finale of a five-game road trip. They also lost ground to Calgary in their bid for the final playoff berth in the West.
