LOS ANGELES — Alec Martinez scored with 5:17 left in the second overtime and the Kings won their second Stanley Cup in three years with a 3-2 win over the Rangers in Game 5 of the final Friday night.
Los Angeles became the first team in 34 years to win the Cup on home ice in overtime. The last was the 1980 Islanders.
"That's what we were talking about in the locker room, that we had to dig deep," Martinez said. "We were able to battle back."
The Kings' Justin Williams, whose first-period goal gave the Kings a 1-0 lead in the game in the first period, was voted the winner of the Conn Smythe Trophy as the playoff MVP.
Marian Gaborik scored the tying goal on a power play with 12:04 left in regulation for the Kings.
The Rangers took a 2-1 lead in the second period when Chris Kreider scored on a power play and Brian Boyle added a short-handed score with 30 seconds left in the period. New York was trying to avoid elimination again after winning Game 4 at Madison Square Garden.
Henrik Lundqvist stopped 44 shots in another standout performance, but Gaborik poked the tying goal between his legs on a rebound for his 14th goal in a spectacular postseason by the Kings' late-season acquisition.
The finalists headed to overtime for the third time in their three games at Staples Center, and they needed a second OT period for the second time.
Both teams had tantalizing scoring chances in the first overtime but couldn't convert.
Ryan McDonagh hit Jonathan Quick's post with a long shot during an early power play. Tyler Toffoli rang a shot off Lundqvist's post with 7:15 left, and the Kings trapped New York in its own end for an exhausting stretch late in the period.
Kreider got a breakaway in the final minute after Kings defenseman Drew Doughty fell down, but he missed the net.
After falling behind early, New York outplayed the Kings and finally got the equalizer with 4:23 left in the second period while Dwight King was in the box for high-sticking. After several sharp passes in a prolonged possession, Ryan McDonagh found Kreider in front for New York's second power-play score of the series.
Boyle then got a stunner, capitalizing on the Kings' poor power-play work in the final minute of the period. He skated around Doughty and wired a shot into the far top corner behind Quick with 29 seconds left.
It was Boyle's third goal in 25 postseason games.
Los Angeles got another big-game goal from Williams, who put the Kings ahead just 6:04 into Game 5 after linemates Dwight King and Jarret Stoll applied pressure on Lundqvist.
