ANAHEIM -- Frederik Andersen emerged in the hallway outside the Anaheim Ducks locker room nearly an hour after Game 2 of the Western Conference Final had ended.

The second-year goalie understandably spent more time than usual hydrating and getting treatment but exhibited his usual calm after making a career-high 53 saves in a 3-2 triple-overtime loss to the Chicago Blackhawks at Honda Center.

Andersen couldn't remember playing a longer game. Ever.

"I'm not sure," Andersen said. "I think this is by far. I don't think I've ever gone to a second OT, actually."

It seemed wrong that he was beaten on a missed defensive assignment when Chicago's Marcus Kruger was left open in front of the net to tap in Brent Seabrook's shot at 16:12 of the third overtime to even the best-of-7 series at 1-1.

Andersen was visibly upset on the ice but wouldn't let on afterward.

His teammates spoke for him though.

"That's not his fault," Ducks left wing Patrick Maroon said. "Throw pucks at the net, hit off a guy -- that's nothing he can do."

Andersen seemed to get better as the second-longest game in Ducks history, and longest ever at Honda Center, went on.

After Marian Hossa gave Chicago a 2-0 lead on a power play at 6:19 of the first period, Andersen didn't allow another goal for 99:53, until Kruger's game-winner. He made tough saves on Antoine Vermette and Patrick Kane in the first overtime, and then stopped Andrew Shaw on a point-blank shot in the crease and made a glove save on Vermette with 58 seconds to go in the second overtime. He made his career-high 50th save with a glove grab of Teuvo Teravainen's shot early in the third overtime.

Andersen's previous career high, in the regular season or Stanley Cup Playoffs, was 49 saves against the Carolina Hurricanes on March 2, 2014. He is known for his remarkable steadiness, and even after more than 116 minutes minutes of hockey against the highly skilled Blackhawks, he didn't show any signs of being drained.

"You've just got to keep thinking about the next shot, the next shot," Andersen said. "There's nothing really more to that."

Ducks left wing Andrew Cogliano acknowledged what it means to have Andersen playing so well going into Game 3 on Thursday at United Center (8 p.m. ET; NBCSN, CBC, TVA Sports).

"He's dialed in right now," Cogliano said. "No one's worried about him at all. I think he's the reason why we're playing this game really good right now. I don't think anyone's giving us a lot of credit against Chicago. Obviously Chicago is a great team, but I think we're playing pretty good."

Andersen said he felt "fine" and "all right" as Tuesday turned into Wednesday in the dimmed hallway at Honda Center. The Ducks have a short night's rest before a flight to Chicago, and Andersen acknowledged the loss might linger a little longer than others.

"This is a tough loss," he said. "I think we had some really good chances. It's a tough pill to swallow. But we've got to get one on Thursday."
