Jake Allen stopped 38 shots and the St. Louis Blues edged the Chicago Blackhawks 2-1 on Sunday to move into first place in the Central Division.
David Backes and Olli Jokinen each scored in the second period for the Blues, who have won three straight and leapfrogged Nashville in the division standings. They are one point ahead of the Predators and hold a three-point lead on the Blackhawks with three games remaining for each club.
St. Louis played its fourth straight game without Alexander Steen and third in a row without Vladimir Tarasenko. Both forwards are day-to-day because of lower-body injuries.
Corey Crawford made 31 saves for Chicago, which had its winning streak snapped at four games.
