"I got a chance to go with [Perry and Getzlaf], guys that I had played with this year," Ritchie said. "When I play with them I try to get on the puck, go to the net and just get the puck to them."
Ritchie had two solid scoring opportunities before finishing the third off a pass from defenseman Sami Vatanen after Perry's shot had gone wide.
"Sometimes in games, you get a few chances early," Ritchie said. "The puck follows you a little bit, and I think tonight I had some of my best chances of the series and finally capitalized."
Ritchie said the scoring play began with old-fashioned hard work.
"We kind of just had a forecheck off a broken play. Sami made a good pass in the middle and I got it on the net and it went in," he said. "We got a break there, I think."
Few were happier to see the shot hit the net than Getzlaf, who celebrated his 32nd birthday.
"It's huge," he said. "Ritchie's a kid that's been playing great all season. He's doing some good things, he's learning along the way. He played with us for at least half the game tonight and made a big contribution."
Ducks forward Andrew Cogliano, who scored his first goal of the playoffs to tie the game at 1-1 in the second period, said similar contributions will be required against the Predators.
"We said it after last game, we needed other guys to step up and give some support to guys like [Getzlaf, Rickard Rakell] and [Jakob Silfverberg]," Cogliano said. "They've been carrying the load for the last couple series. We're going to need other guys to step up and score big goals."
