Andy McDonald scored twice, and got more cheers than the Ducks did in Honda Center.
The Ducks had their chances early but failed to execute, going 0-for-3 on their first-period power play attempts and finishing 0-for-6. St. Louis, meanwhile, went 2-for-6 officially, but also scored their fourth goal with Joffrey Lupul a few steps out of the box.
Jonas Hiller (9-of-12) was pulled from his first start of the season, and Jean-Sebastien Giguere (18-of-20) fared slightly better in relief.
But the Ducks were clearly frustrated by their own shortcomings and a fine night by Ty Conklin (26-of-26), taking an unsportsmanlike penalty and, later, a fight during a commercial break in the third period.
More details in tomorrow’s editions.
