PITTSBURGH — Kris Letang scored twice, including the go-ahead goal in the third period, and the undermanned Pittsburgh Penguins rallied to win their fifth straight, 4-2 over the Dallas Stars on Friday night.

Letang dangled his way past a sliding Tyler Seguin to skate in and beat Anton Khudobin from in close 6:34 into the third, giving Pittsburgh its first lead. Patric Hornqvist doubled the advantage with 9:40 to go when he stood in the slot and deflected a point shot by Dominik Simon for his third goal of the season.

Jared McCann also picked up his third goal for the Penguins, who have won five straight despite playing without a handful of forwards, including star center Evgeni Malkin. Letang added an empty-netter in the final seconds to give him four goals this month. The veteran defenseman scored just 16 times last season. Matt Murray finished with 22 saves for Pittsburgh.
