Handzus scored his second goal of the postseason 2:04 into double overtime to beat the Los Angeles Kings 5-4 at United Center and force the Western Conference Final to a Game 6 on Friday at Staples Center (9 p.m. ET; NBCSN, CBC, RDS).
The Kings lead the best-of-7 series 3-2.
Handzus played 14:30 in Game 5 but saw the ice for 1:38 in the third period, 2:43 in the first overtime and 19 seconds in the second OT. He came into the game minus-6 with two points (one goal) in Chicago's 16 previous postseason games.
"You still have to have a lot of confidence in yourself," the 37-year-old center said. "I'm not real happy how [I've] played, but [I've] just got to be confident. It's a lot of fun to be playing in the playoffs. It's conference finals. You cannot just look at yourself all the time, be down [and] be disappointed. You just got to be positive. If you don't want be positive, then probably you won't get out of the slump or anything. I stay positive. I'm [a] better player than [I've] showed. [I'll] try to show it next game again."
