Bishop finished second in the NHL during the regular season with a 1.98 goals-against average and led the League with a Stars record .934 save percentage. Monday was the first time that he allowed more than two goals since giving up four in a 5-4 win against the Arizona Coyotes on Feb. 4.
Granlund, acquired Feb. 25 in a trade from the Minnesota Wild, scored on a wrist shot from just inside the blue line along the right boards that sailed through traffic for the game-winner.
"One of those, you try to score, you can't get anything, and then all of a sudden one of those go in," said Granlund, who scored one goal in 16 regular-season games with the Predators.
Bishop said the goal was deflected in.
Grimaldi took an outlet pass from P.K. Subban just inside the offensive zone and made the score 1-0 at 4:29 of the second period on a 31-foot wrist shot from the right boards that caught Bishop under the right arm. Grimaldi, a five-year NHL veteran, had scored his first career playoff goal Saturday in the 2-1 overtime Nashville win.
