BIG TIME POTTER (4) has missed the frame the last couple but was a Class 1 winner three back (17.87) at this track over 305m. Has the ability and looks like a key chance here. ZERO CHILL (7) wasn't far away at the finish when 4th and beaten only 4.5 lengths (18.29) at Wanganui Straight. Cannot be underestimated. SISTER SHADOW (2) had been in super honest form, hitting the frame two times on end before finishing fourth (18.37) at Wanganui Straight last time. Has performed well from this box with a win and five minor placings to her name from nine starts. Great chance to atone. GOLDSTAR MACKAY (6) should bounce back after an unplaced effort here recently. Each way value.
