Alexandar Georgiev, who started the opener and the finale of the Rangers' three-game Western swing and appeared in all three, made 27 saves in this one and 76 on the road trip. Two of the three goals Vegas scored on him came on breakaways, the other on a power play.
Most of any of them, the harshest blow to the Rangers was Marchessault's score late in the second period. It came just moments after Cody McLeod had a pair of splendid chances to halve the deficit on the same shift, set up by each of his linemates. First he drove the net for Pavel Buchnevich to fire one off his tape that couldn't find Fleury's five-hole, then he walked in alone off of Boo Nieves' tap pass around Deryk Engelland, but a flopping Fleury managed to keep that one out too.
Only a half-minute after that, Marc Staal's deflected shot off the backboards caromed 125 feet out to the Rangers' blue line and into Marchessault's path for a breakaway, and he flicked one up top on Georgiev for his 14th goal just 1:07 before the period was out.
It was a two-goal swing and gave a three-goal cushion to a team that is now 18-0-2 when leading after 40 minutes.
But as Brady Skjei said, "I thought we kept playing," and Kreider said it might have been Henrik Lundqvist who was making use of a ketchup metaphor in between periods. "You hit the ketchup bottle over and over again, it comes out all at once if you just keep hitting it over and over," said Kreider, whose assist was his ninth point in the last nine games. "That's a good analogy."
They scored a pretty good goal with 8:17 to play when Zibanejad finished off passing play with his linemates. First Mats Zuccarello, moved onto that line for the third, handled Kreider's pass in his skates at the right circle, then he sent one back across the netmouth for Zibanejad, who went to one knee to tee it up with his skate and stuffed it into the open side.
Zibanejad has scored a goal in each of the Rangers' four games against the Golden Knights since Vegas entered the league.
Along with the back-to-back stops on McLeod, Fleury's biggest save of the night came with the clock ticking under 3½ minutes, when Tony DeAngelo took Fast's pass in space at the right circle, only to see the goaltender snare his rising wrister with the catching glove.
Quinn brought Georgiev to the bench with 2½ minutes left, but Carpenter's hit the empty net with 1:20 to play. Fast supplied the final score line 23 seconds from the end when the rebound of Jimmy Vesey's shot popped out to him in the slot.
