Holloway made it 3-2 at 7:51 of the second period, taking a pass in the high slot from Sam Carrick and beating Talbot under his glove with a wrist shot.
Zach Hyman, who had a hat trick in Game 1, tied it 3-3 with a power-play goal at 10:33. He took a cross-ice pass from Draisaitl and buried a one-timer from the left circle into an open net.
Kevin Fiala put the Kings ahead 4-3 at 1:46 of the third period, scoring with a one-timer from along the right boards that appeared to catch Skinner by surprise.
“Since the third period of Game 1, just some really tough bounces are happening,” Skinner said. “That's not saying that it leaked into tonight, it’s just that they're getting some good puck luck right now. We've also had our fair share of puck luck as well.
“That's how hockey works sometimes. Luck wasn't on my side tonight.”
Holloway tied it 4-4 at 3:23, roofing a shot glove side from the top of the right circle.
“In the first period, we dug ourselves a big hole being down 2-0 and 3-1, but after that I thought we played a lot better, especially in the second period,” Knoblauch. “I felt like if we were ever able to get the lead we could have finished the game, but we were never quite able to do that."
