KNOW DEFENCE (8) comes into this as the quickest on the card winner last time at Ascot Park, scoring by 0.8 lengths (43.43). Rates on top again. KNOW EXPENSE (2) finished in the minors last time but the start prior broke the clock when winning over 525m at this track, taking a Class 2/3 in a fast 30.28. Smart winner two back and looks a key chance on that form. GOLDSTAR JOBLIN (6) finished third (30.32) two back at this track but out of the placings last time when 6th there. Expected to give a good account. PRYOR BALE (4) has won at this course and distance and warrants respect.
