WHO KNOWS IT (4) filled a minor placing two back then scored her maiden win (27.88) at this track over 450m last time. Yet to win here but has run some good races. Rates to win again. LIGHTFOOT SADIE (3) finished in the placings last time but could not have been more impressive before that in her fast 15.92 win at this track over 261m. Expecting another bold showing. MARINAS CALGARY (1) was a last start winner from the inside trap at this track and distance (28.13), scoring by 1.5 lengths. Can measure up again. BARNFIELD CHIEF (6) is in the mix despite finishing out of the placings here last start.
