NASHVILLE, Tenn. — Pekka Rinne is a friendly, polite man off the ice. Slipping the puck past the Nashville Predators goaltender is one of the few ways to anger the 6-foot-5 Finn.

Pucks bouncing past him on the NHL’s biggest stage infuriate him. Rinne chopped his stick against a goalpost not once, but twice after giving up a fifth and final goal a year ago when Nashville was ousted from the playoffs.

That was just Game 7 in the second round.

Now Rinne goes into the biggest game of his career Sunday night needing yet another home victory to force both the defending champs and the Stanley Cup Final to a deciding seventh game back in Pittsburgh. And Rinne spent the past 40 minutes stewing on the bench as the Penguins finished off a 6-0 rout Thursday night in easily Nashville’s worst playoff loss.

“You have those thoughts that why (is) the puck getting deflected in off our guys or something like that,” Rinne said Saturday. “You try to work so hard that the luck is also on your side. When bounces not going your way, sometimes you question, have second thoughts in your head, but that’s life.”

The goalie so competitive he doesn’t like teammates scoring on him in practice is back in Nashville where he’s been nearly unbeatable over the past two postseasons at 13-1.

Rinne has a 9-1 record this spring with a 1.44 goals-against average and .949 save percentage in Nashville. He’s allowed two or fewer goals in eight of those 10 games and tied Antti Niemi with his 36th playoff win for the most in NHL history by a Finnish-born goaltender.

Yet the goalie and the Predators stand between Pittsburgh and a big chunk of history.

The Penguins are trying to become the first team to win the Stanley Cup in consecutive seasons since Detroit repeated in 1997 and 1998. One more win gives the Penguins the franchise’s fifth Stanley Cup, tying them with Edmonton for sixth all-time.

All four of Pittsburgh’s Stanley Cups have been clinched on the road.

“Opportunities like this, they don’t come around often, so you want to make the most of them,” Pittsburgh captain Sidney Crosby said.

The Predators haven’t scored a goal in 63 minutes, 23 seconds since Filip Forsberg’s empty-net goal in Game 4. So Rinne will need to be at his best to give Nashville a chance at its first Game 7 and Pittsburgh’s third this postseason.

Rinne understands coach Peter Laviolette was trying to wake up the Predators by pulling the veteran after allowing three goals on nine shots in the first 20 minutes of Game 5. Crosby, Evgeni Malkin and Phil Kessel all had at least two points.
