WHATS UP MAC (4) produced a moderate effort last time when fifth at this track over 480m behind Brucey Bonus (30.42) in an A10. Can atone. STRAIGHT FIRE (5) turned in a solid run last start over 480m at this track finishing 4th and beaten only 4 lengths (30.89). Key player if finds best. DRIVE ON SHELBY (2) missed the frame on debut when fourth (30.28) at this track over 480m. Can improve sharply here. DARLEY DIGGER (1) should bounce back after an unplaced effort here recently.
