Hornqvist had two goals and an assist and the Penguins defeated the Detroit Red Wings 5-1 on Sunday.

“Sometimes you get lucky out there and you keep shooting and keep finding the back of the net,” Hornqvist said. “It was one of those afternoons. It’s always fun to score.”

Hornqvist has 14 goals this season. Sidney Crosby scored his 11th of the season, Kris Letang added his 14th on the power play and Sam Lafferty also scored for Pittsburgh, which moved within one point of first-place Washington in the Metropolitan Division.

Crosby continued a four-game point streak on Sunday. He has six goals and 19 points in 12 games since returning from core muscle surgery on Jan. 14.

Matt Murray made 27 saves for Pittsburgh, which has won 11 of its past 15 games.

“For the most part, I think we’re trending the right way and to me, that’s encouraging,” Penguins coach Mike Sullivan said. “I think we’re getting back to the game that has brought us success most of the year. There are always ways we can get better and improve, and we’re going to push this group to try and get to another level.”

Valtteri Filppula scored his fifth of the season for Detroit, which lost its fourth straight game. The Red Wings have been outscored 16-5 in their past four games and 59-23 in their past 16. Detroit has lost 14 of its past 16 games.

Sunday’s loss was the third straight game, and the second time in as many days, that the Red Wings gave up four unanswered goals after taking a 1-0 lead. The Red Wings lost 4-1 at Boston on Saturday.

Jimmy Howard made 12 saves, but was pulled after Crosby’s goal gave Pittsburgh a 4-1 lead in the second period. Jonathan Bernier stopped 18 of 19 shots.

“When things are going poorly, it’s easy to point fingers, but we’re all part of the problem,” Red Wings forward Luke Glendening said. “We have to look within ourselves and see how we can be part of the solution.”

Filppula opened the scoring at 5:37 of the first period before Lafferty tied it at 1-1 a couple of minutes later. It was the first of three goals from the Penguins’ fourth line.
