LAB RAT (3) has been in the market at his last couple of starts but hasn't made an impression, last start finishing seventh over 1509m at this track. Can improve and is a leading player on best figures. HEY BIG UN (1) disappointed last time when fifth over 1609m at this track after a close second at this track the run prior. Appeals back in trip this time so should prove tough to beat. THE RONALD (4) is experiencing a long win drought, extended last start when fourth over 1509m at this track. Likely improver with strong prospects. MASTER OF DISGUISE (2) finished third last start over 1207m at this track, beaten 0.8 lengths. Likely improver with bright prospects.
