ANCIENT WORLD (5) wasted no time getting off the mark as favourite on debut over 6f at Fairgrounds (Dirt) six weeks ago. Likely improver who should run well again. WALKING IN MEMPHIS (7) was out of the money two runs back then again missed the frame last start over 1m1/2f at Gulfstream Park, beaten 2 lengths into fourth after being in contention on the bend. Finds a tougher race but a big run will not surprise. SEXAGENARIAN (1) resumes after a break of eight months. Hoping for a repeat of his debut win over 5½f at Ellis Park to kick off last prep. Sure to make his presence felt. MISCHIEF RIVER (8) returns from a lay-off of six-and-a-half months and is having his first run for a new yard. Was a winner when fresh last campaign at Los Alamitos (Dirt) over 5f.
