Erik Christensen scored two goals and Devin Setoguchi one for the Wild, who have lost six of their last seven games. Matt Hackett made 21 saves for the Wild.
Baertschi, the 13th pick in last year's NHL Entry Draft, gave the Flames a 2-0 lead at 1:43 in the third period, scoring on his own rebound for his first career goal. Christensen answered with two goals 2:20 apart.
Glencross scored into an open net at 10:17 of the third period for his career-high 25th goal of the season. His seven-game goal streak is one short of the club record held by Kent Nilsson (1983-84) and Gary Roberts (1992-93).
