"I think I've had some opportunities," Faulk said. "I don't think I've had a ton of them that I'm breaking my stick over the post or something, that I'm trying to switch them thinking something's wrong there. It was a little tough stretch there, and I knew one would go in eventually.
"You've just got to stick with it, keep shooting pucks and try and get pucks through and onto the net."
Walker, called up from San Antonio of the American Hockey League on Sunday, put St. Louis back in front at 2-1 at 14:01 of the second period after Lafferty tied it 1-1 at 6:27.
Walker batted a deflected puck out of the air just before it could hit the ice.
"I wasn't offside this time," said Walker, who had a goal overturned in a 3-1 win against the Dallas Stars on Friday after a coach's challenge for offside. "... That's actually one thing I kind of work on in the summer was batting pucks out of the air like that, trying to meet them when they hit the ice. I think I just got a little lucky there as well. I'm sure a goalie's really not expecting that. I just tried to get it on net, and fortunately it went in the net."
