Perry, more than anybody, had the chances to get it done Wednesday, to at least tie it and force overtime.
"We still believed in the third period that we were going to tie it up," Boudreau said. "It just wasn't to be."
The Ducks got a goal 1:45 into the third, on the power play, from alternate captain Ryan Kesler. They had 18:15 to find the equalizer, to erase a disastrous stretch of 9:34 in the first period that saw the Predators score two goals.
Perry, who did not have a goal in the series, led the charge. He had five shots on goal in the third period, four in the final 75 seconds. His other shot attempt, with four seconds remaining, was blocked by defenseman Roman Josi, the last of 24 blocked shots for the Predators.
"I know one thing; he left it all out there today," Boudreau said of Perry. "He tried his [butt] off. It's not easy to score goals, and we would have obviously loved one in the third.
"He had five or six good chances, but he was snakebit the whole series. I mean, it was tough, but it wasn't for lack of his effort tonight."
