A back injury to goaltender Curtis Sanford has opened the door for Steve Mason to reclaim his No.1 job with the Blue Jackets.

Nobody can say what the future holds for Mason — he's under contract through 2012-13 at $3.2 million a season — but it's never too late for him to start playing well.

"I think (Mason) has put together nine good periods of pretty good hockey now," interim coach Todd Richards said after the 2-1 win on Tuesday over the St. Louis Blues. "I know we gave up five goals versus Anaheim, three of them on the power play. Other than that, he's been terrific."
