The Stanley Cup finals are shifting back to Pittsburgh after the Nashville Predators earned two convincing home wins over the Penguins at Bridgestone Arena to even the best-of-seven series, 2-2.

There has yet to be a competitive game from start to finish, with both clubs dominating on their home ice. After the Penguins outscored the Predators by a combined scored of 9-4 in Games 1 and 2, the Predators followed it up by outscoring the Penguins, 9-1, in Games 3 and 4.

The Penguins have home-ice advantage with three games remaining and are still the favorites at -131, while the Predators are listed at +111, according to BetOnline.

Before the start of the series, the Penguins had -150 odds to win, while the Predators were +130 underdogs. Before Game 4, the Penguins were -200 favorites compared to the Predators at +170, according to odds from Bovada.

For Game 5 at PPG Paints Arena, the Penguins are -142 favorites compared to the Predators at +129, according to Oddsshark.

The series has proven to be consistent with the way the two clubs played in the regular season. The Penguins finished with the least number of losses (6) in the regular season, while the Predators finished with the third-fewest number of losses (9).

The Penguins have remained the favorite, but there hasn't been an overwhelming amount of confidence about their chances. After a 5-3 win in Game 1, Pittsburgh head coach Mike Sullivan seemed to admit that the final score was misleading and that the series was going to be competitive, as the Predators outshot the Penguins, 26-12.

"None of us in our dressing room is fooled by the score tonight," Sullivan said.

The Predators have outshot the Penguins in all four games.

The Penguins may be due for a big game from Sidney Crosby. The superstar forward scored in Game 4 after five consecutive games without a goal.
