The unbeaten Group 1 Blue Diamond Stakes contender Field Of Play has officially secured a start in Saturday’s prestigious race after his connections opted to pay the $55,000 late entry fee following a strong gallop at Cranbourne.

Though not initially nominated, the deadline for payment was Monday morning. Co-trainer Trent Busuttin confirmed on Sunday that the decision was locked in.

“We paid up for him after he galloped on Saturday,” Busuttin said. “We’re very happy with him and he’s a horse that’s got no issues.

“He’s a very straight-forward horse. He eats, sleeps and he bounced through the race well and the same with the gallop, so we made the payment.

“Hopefully we get through the week, and he’ll go in with every chance.”

Deep Field’s talented son was acquired as a weanling for $255,000 before later selling for $500,000 at a yearling sale. Jockey Blake Shinn will take the reins for the big race.

According to leading online bookmakers, Field Of Play shares $7 co-favouritism with Palm Angel, while Our Gladiola sits just behind at $7.50.
