Victor Rask's 27th goal of the season midway through the third was the difference, as the Calgary Hitmen edged the Kelowna Rockets 2-1 Sunday afternoon at the Saddledome.  Calgary's Jimmy Bubnick and Kelowna's Brent Bulmer traded first period goals while the two teams played to a stalemate in the second period.  Brandon Glover made 26 saves, including 12 in the third period, in the win while Jordon Cooke made 30 saves for the Rockets.  The Hitmen, who moved into 4th place in the Eastern Conference with the win, are back in action Wednesday when they host Swift Current.
