Couture's goal with 3:52 remaining in the third period Saturday sent the Sharks to a 3-2 victory over the Buffalo Sabres.
"We'll take six (points). We wanted eight," Couture said. "There was a couple games that we lost that were winnable games. But I think we were chasing it, but we were happy to finish it with a win."
Couture scored the winner on a wrist shot from the left circle that went over Robin Lehner's shoulder. It was his eighth of the year and fifth on the road trip.
