Blackwell tied it 1-1 at 6:40 of the second period on a shot from the left circle. Ryan Strome had an assist to extend his point streak to 11 games (two goals, 14 assists). He also has a 10-game assist streak, tying Rod Gilbert for the second-longest in Rangers history behind Brian Leetch (15 games, 1991-92).
"Honestly, don't try to think about it too much," Strome said. "I just try to go out there and make plays. Right now we have the puck a lot, which is fun. Even tonight we had so many chances for more goals. Things are clicking right now, so just try to make the play that I see in front of me.
"To be in that company is a nice honor, but this time of the year, even though it's a cliche, just finding ways to get wins is important. We want to play meaningful games here down the stretch. I think we've worked really hard here to give ourselves a chance to do that. Obviously it feels good to be helping the team out at this time also."
Chytil made it 2-1 when he lifted a loose puck over a sprawled Tokarski at 6:17 of the third period.
Buffalo was playing the second game of a back to back after its 6-1 win against the Philadelphia Flyers on Wednesday, and its third game in four nights.
"We battled a lot of fatigue tonight," Sabres coach Don Granato said. "It was obvious we had the great energy in the first and it looked like we just died from the energy standpoint in the second. We reverted back to a lot of hesitation, and that's a real sign of fatigue. … Then you saw a little bit of it at the start of the third, missing the net on shots that were point-blank, so a lot of characteristics of that. I thought our guys elevated tremendously in the last few minutes to get that goal."
