SPEEDY CHECKOUT (4) was popular in betting last start but disappointed when 2 lengths away in fourth (28.26). Was in the money the start prior. Key runner on her best form. MARLFIELD DAISY (6) followed a moderate sixth at this track two runs ago with another plain effort last time to finish fourth, beaten 4.5 lengths, in an A3 at this track over 450m (28.27). Suited here and looks a leading player on best. BLACKWONDERBOSS (3) has a strong winning strike-rate here with three wins and a placing from eight tries. Below best last time at this track (28.15) in an A3, finishing a 2.5 lengths fifth. Can feature in the finish. ANGLESEY ROLEX (2) is going well, filling a minor placing two back then was a 1.75 lengths winner of an A5 at this track over 450m (28.40). Up a notch this time but in form and sure to give a good account.
