Chicago (29-5-4) had fallen behind 3-2 early in the third on a goal by David Legwand, but Saad and Toews connected against Pekka Rinne to put the Blackhawks back ahead. The Blackhawks defeated the Predators for the second time in two days and improved to 13-0-1 against Central Division teams. Andrew Shaw and Bryan Bickell also scored for Chicago, and Patrick Kane added an empty-net goal. Shea Weber and Nick Spaling each had a goal and an assist for the Predators (15-17-8), who are 13th in the Western Conference with 38 points, five behind eighth-place Detroit at the postseason cutoff. Chicago's Ray Emery stopped 19 shots, following a 20-save, 1-0 win at Nashville on Saturday. The Blackhawks improved to 4-0 against the Predators.

Steve Ott extended his goal streak to three games, and Patrick Kaleta also scored for Buffalo, which won its third straight. Stars 5, Sharks 4, SO: Jamie Benn scored the lone goal in the shootout and Kari Lehtonen stopped all three attempts as Dallas snapped San Jose's seven-game winning streak with a come-from-behind victory.

Eric Nystrom also scored, and Lehtonen made 32 saves through overtime for Dallas. The Stars also erased a 2-0 deficit before falling behind 4-2. Tommy Wingels, Brent Burns, TJ Galiardi and Marc-Edouard Vlasic scored for the Sharks, who had won the first six games of their seven-game homestand.
