ST. LOUIS -- Andy McDonald scored two goals and had an assist to lead the St. Louis Blues to a 6-1 victory over the Columbus Blue Jackets on Tuesday night.

St. Louis broke open a 2-0 game with four third-period goals.

David Backes scored the only goal of a relatively listless first period, beating Columbus goalie Fredrik Norrena for his fifth goal of the season.

Norrena was starting in place of Pascal Leclaire, who was scratched with a viral infection. Two of Leclaire's NHL leading seven shutouts this season are against St. Louis. Norrena (6-10-3) made 25 saves on 31 shots in the loss.

McDonald gave the Blues a 2-0 lead midway through the second period off a pass from ookie David Perron.

McDonald scored his seventh goal of the season less than 2 minutes into the third period on a pass from Brad Boyes. McDonald one-timed it past Norrena.

Columbus' only goal came when Rick Nash took a Joakim Lindstrom pass from the right side and beat Manny Legace for his 22nd goal of the season. It was the first goal Legace had allowed in 187 minutes and 39 seconds, a team record.

Keith Tkachuk, Perron and Dan Hinote added third-period goals.
