The Penguins held off the hard-charging Predators, who were making their first appearance in the Stanley Cup finals after they had entered the playoffs as the lowest seed in the Western Conference.
The Penguins, who beat the San Jose Sharks in the finals last season, have now won five championships, all of them since 1991; no other N.H.L.
This Stanley Cup is the third for Crosby, 29, the Penguins’ team captain and perhaps the N.H.L.’s most recognizable star, who was also won his second consecutive Conn Smythe Trophy as the most valuable player of the playoffs.
The Predators mounted a ferocious attack in the third period, but their power-play unit came up short again midway through the period.
In the end, it was Hornqvist, who played his first six seasons in Nashville, and the Penguins who were able to score from close range, and as the final seconds ticked off, the Predators fans could only watch in stunned amazement as the Penguins won yet another Cup.
