He scored the tiebreaking goal in the third period against his former team, helping the Chicago Blackhawks rally for a 3-2 victory over Detroit on Friday.
Lang signed with the Blackhawks as a free agent during the summer after playing with the Red Wings for three seasons.
"It was just fun," Lang said of his first trip to Joe Louis Arena.
He converted a power-play chance 9:19 into the third. His one-time slap shot from the top of the left circle bounced in off Hasek's shoulder and gave Chicago a 3-2 lead.
"Just got off a good shot," Lang said. "Went in off his shoulder, got one by Dom."
It was the second time in less than a week that he has scored a big goal against his old team. He tied the game late in the third period last Saturday in a 4-3 shootout win over the Red Wings in Chicago.
Lang and Detroit coach Mike Babcock were never comfortable with one another.
"He's got a lot of ability," Babcock said. "There's never been any question about that."
Lang, whose two goals and assist this season have all come against the Red Wings, also didn't dwell on the relationship.
"A lot of good memories," he said. "I can't say anything bad."
"I think we started good and had a good first 15 minutes," Zetterberg said. "... But then we stopped."
The Blackhawks scored twice within 1:01 late in the second period to tie it at 2.
Sharp put in a loose puck from a goal-mouth scramble for a power-play goal with 2:27 left in the second, and Seabrook beat Hasek with a screened wrist shot from the point with 1:26 remaining in the period.
Chicago had gone 10 power-play chances without a goal in its first three games, but was 2-for-8 on Friday night.
"The power play's coming. We're shooting a lot," Blackhawks coach Denis Savard said. "We had a lot of chances and came through tonight."
Two fortunate bounces gave Detroit a 2-0 lead in the first period.
Zetterberg's attempted pass across the crease deflected in off the skate of Chicago defenseman Brent Sopel 7:26 into the opening period. Draper's shot from the high slot area trickled through Khabibulin and the Blackhawks goaltender knocked the puck into the net himself as he tried to grab it off the goal line.
"After the first period, we started playing well," Lang said.
- Sopel went to Detroit's training camp as a free agent invitee and played in most of the exhibition games before signing with Chicago.
- The Red Wings wore their usual road white jerseys, and the Blackhawks were in their usual home red jerseys.
- Zetterberg has at least a point in all five of Detroit's games.
