Mac De Lago and Dynamic were the big movers in the Vodacom Durban July betting yesterday as bookmakers assessed the results, and likely impact, of Saturday’s big Greyville races.

Word Sports Betting cut the promoted Rising Sun Gold Challenge winner from 18-1 to 11-1 while Betting World shortened Weiho Marwing’s charge from 16-1 to 10-1. Dynamic, as big as 50-1 before his second to Exit Here in the Cup Trial, is now a best-priced 22-1.

French Navy, who ran on in eye-catching style to take third in the Gold Challenge, was shortened from 11-1 to 9-1 by WSB and is 8-1 with Betting World. However the layers were unimpressed with fourth-placed New Predator and marked him out from 60-1 to as big as 90-1. Black Arthur remains favourite at 11-2 (5-1 with Betting World) and Marinaresco has shortened a point to 6-1.
