NASHVILLE, Tenn. -- Nashville Predators rookie Frederick Gaudreau has no problem performing on hockey's biggest stage.

The 23-year-old undrafted free agent hadn't scored an NHL goal before the start of the Stanley Cup Final. However, Gaudreau scored his second straight game-winning goal -- and third goal of the Final -- on Monday to pace the Predators to a 4-1 victory over the Pittsburgh Penguins in Game 4.

Nashville won its second straight game and sent the series back to Pittsburgh tied 2-2. Game 5 is on Thursday.

The defending Stanley Cup champion Penguins were outshot for the fourth straight game.

Predators goalie Pekka Rinne was spectacular in the victory, making a handful of close-range saves among his 23 stops. He improved to 9-1 at home in the postseason.

The Predators scored twice in the second period, taking a 3-1 lead on goals by Gaudreau and Viktor Arvidsson.

Gaudreau's goal came 3:45 into the period on a wraparound, but there was no goal signal on the ice at the time. The NHL stopped play shortly thereafter, awarding Gaudreau the score after a review clearly showed the puck crossed the line.

Gaudreau played just nine regular-season games this year and didn't score a goal.

Rinne made a spectacular diving save midway through the second to keep the score 2-1, foiling Jake Guentzel by knocking the puck out of the crease just before it crossed the goal line.

Arvidsson doubled the Preds' lead with 6:52 left in the second period, scoring on a breakaway after Mike Fisher's diving pass in neutral ice sent him in alone. It was the first playoff goal for Arvidsson since Game 4 of the first round, and it put Nashville up 3-1.

Filip Forsberg's empty-net goal at 16:37 of the third period completed the scoring.

The Predators had jumped out to a 1-0 lead with 5:09 left in the first period when center Calle Jarnkrok knocked home a rebound as he went sailing into the crease. Matt Murray (22 saves) had stopped Craig Smith's initial deflection of Austin Watson's shot, but Jarnkrok's follow gave him five points -- one goal and four assists -- in the past five games.

Minutes later, just as the Nashville crowd was getting revved up -- giving the team its first standing ovation of the contest -- the Penguins struck back.

Sidney Crosby, who had been held without a shot on goal in Game 2, jumped on a loose puck and cruised in on a breakaway. He deked Rinne, then slid a backhand shot that tapped the post before settling behind the goalie at 15:57.
