DIRTY RICH (1) went forward and proved too strong when resuming last time out, scoring by 1.75 lengths over 1106m in Listed grade at this track (Dirt). Likely improver with strong prospects. OBLITERATION (6) resumes after a break of nine weeks. Did win at his only other first-up run when on debut, scoring over 1106m at Churchill Downs. Makes plenty of appeal. CANNED HEAT (5) was a most impressive winner last time over 1106m at Remington Park (Dirt), scoring by 3 lengths. Is in solid form this time in work, scoring two times and placing on three occasions from six starts. Looks one of the prime contenders. HOW BOUT THAT CURT (4) is back from a spell of four months. Closed last prep as a winner, taking out a 1207m contest at Canterbury Park by 5 lengths. Is yet to miss the placings in three starts, including two wins. A bold showing is expected.
