Of his last 12 shots on goal, Chris Stewart has put eight of them in the net. Continuing a torrid offensive streak, Stewart scored a hat trick in the Blues’ 6-0 victory over Edmonton on Saturday night at Rexall Place. “You get into streaks like that, you just start shooting it, pucks find a way to go in,’’ Stewart said. “Huge compliment to my linemates tonight. They gave me lots of prime-time scoring chances.’’ But the news for the Blues was not all good. Forward Alexander Steen, the team’s leading scorer, did not return after the second period. Following the game, coach Ken Hitchcok did not have an update on Steen’s status. Stewart’s first hat trick as a Blue and Brian Elliott’s 14th shutout with the club helped the visitors win their 10th road game this season, avoiding a two-game trap before they break for Christmas. On a swing through Alberta, the club is visiting Edmonton and Calgary, seated No. 14 and 13, respectively, in the Western Conference standings. The trip began Saturday against Edmonton, which entered the game on its fourth five-game losing streak of the season and holding a home record at Rexall Place of 5-10-1. The Blues, splitting up the goaltending duties for the last two games before the holiday, turned to backup Elliott. He withstood heavy early pressure before a streaking Stewart triggered the club’s offense, sending David Perron and Co. to their sixth consecutive loss and sixth scoreless outing of the season. The Blues play at Calgary on Monday before taking a four-day break.
