Hertl and Keegan Kolesar each had a goal and an assist for Vegas (23-8-3), which has won four in a row and eight of its last nine. Adin Hill made 31 saves.
“We're playing good hockey. We're collecting points, so that's good,” Vegas forward William Karlsson said. “Now we got a three-day break, and we've got to stay on the track."
Mason McTavish scored for Anaheim (13-16-4), which was playing the second game of a back-to-back after defeating the Utah Hockey Club 5-4 in a shootout on Sunday.
“Vegas had control for most of the first two periods. I thought we had a lot of life after the first goal. We pressed until the end,” Anaheim coach Greg Cronin said. “It’s unfortunate we gave up the late goal. We didn’t have a chance to tie in with the pulled goalie. I love the effort. I thought we competed hard.”
Anaheim goalie John Gibson came out of the game at 17:32 of the first period after Tanner Laczynski’s stick caught him in the eye. He made 11 saves. Lukas Dostal made 19 saves in relief.
“He was terrific,” Anaheim defenseman Radko Gudas said of Dostal. “He’s always giving us a chance to win.”
Tanner Pearson scored a shorthanded goal at 19:19 of the first period to make it 1-0 after McTavish turned the puck over in his defensive zone.
