Corey Perry had the puck on his stick with a nearly open net early in overtime, but Martinez managed to block the shot by the Ducks' best goal-scorer.
Several minutes later, Marian Gaborik's game-winner put the Kings up 1-0 in the series heading to Game 2 on Monday night in Anaheim.
The Southern California rivals' first playoff meeting was every bit as entertaining as expected. The Ducks were pleased by their performance despite the loss, while the Kings' defensive depth became even shallower in victory.
For us it's a little bit different. I've never been in front of this much media. This is more than we've ever had to deal with in Tampa. I guess we're on a little bit bigger stage now. It's nice, you have to enjoy it. This doesn't happen too often.
