ANAHEIM, Calif. -- Teemu Selanne has found his game again, back where he left it.
Selanne's return to Anaheim after stints at San Jose and Colorado has the 35-year-old star from Finland skating and scoring in much the same fashion he did earlier in his career.
The nine-time NHL All-Star has eight goals in his first 11 games back in Anaheim, where he scored 225 before being traded in 2001.
"I've been feeling good pretty much all year. It's fun to play again when you're healthy and every stride feels good," Selanne said. "It's a pretty good roll we have here right now."
He gave the Ducks breathing room with his second goal, beating goaltender Reinhard Divis on a breakaway with 9:04 remaining to give Anaheim a two-goal pad.
The loss was the fourth in a row for St. Louis, which hasn't won since a 3-2 victory over the Ducks on Oct. 19. The Blues wasted a lead again, this time jumping out 2-0 before the Ducks came back to go up 3-2 by the end of the first period.
"We grab a 2-0 lead and start taking penalties," Blues coach Mike Kitchen said. "Their power play has been good of late, and you just can't do that.
"It gave them some light and we ended up giving up 23 shots in the first period. You can't do that. We lost the momentum, they got it going and we just couldn't get on our game again and got frustrated."
Eric Weinrich had pulled the Blues close with his first of the season, scoring on a power play 4:08 into the third period to play to make it 5-4.
Jean-Sebastien Giguere, who played a shaky game to that point, shut the Blues out the rest of the way. St. Louis got off 28 shots against him, while the Ducks had 39 against Divis, including the 23 in the opening period.
In the third period, Rob Niedermayer's goal, on an assist from his brother Scott during a power play, had given the Ducks a 5-3 lead 1:09 in.
The Blues' Doug Weight trimmed St. Louis' deficit to 4-3 when he beat Giguere at close range, poking a shot past the sprawling goalie at 18:52 of the second period.
Petr Sykora gave the Ducks a 4-2 lead with a slap shot from the left circle 2:26 into the second period. Jonathan Hedstrom put Anaheim up 3-2 on a breakaway during a power play at 16:38 of the first.
Selanne had evened it at 2 when he scored during a scramble in front of the crease during a power play at 14:42. Four minutes earlier, Joffrey Lupul got his sixth goal to begin the Ducks' comeback.
The Ducks' 23 shots in the opening 20 minutes were their most ever for a first period and second only to the 26 they recorded in a different frame against Florida in 1994.
The Blues got off eight shots in the first.
Eric Brewer's slap shot from 25 feet gave St. Louis a 1-0 lead just 43 seconds in. Scott Young made it 2-0 at 7:28.
Hedstrom also had an assist for his first multipoint game. ... Blues LW Keith Tkachuk will be out three-to-five weeks with cracked ribs. He had an MRI exam Thursday that revealed the injury. Tkachuk was hit by a stick in the midsection during a 4-1 loss to Nashville on Oct. 15 and has played just two games this season. ... The win was Giguere's second in a row since he returned from sitting out three games with a groin injury.
