G1 Randwick Guineas: Runner-by-runner preview and tips Aegon heads the betting for the Randwick Guineas Image: Getty Boom Kiwi gelding Aegon will look to keep his unbeaten record intact when he lines up in Saturday's Group One Randwick Guineas. The Murray Baker and Andrew Forsman-trained galloper made an instant impact in Australia, winning the Hobartville Stakes in style at Rosehill. He'll face a strong field once again, including six of his rivals from the Hobartville. Take a look at the chances of every runner in the race + the suggested betting play �� SPEED MAP Tempo should be pretty solid. Marsannay will roll forward and look to hold the rail from barrier 1. Tim Clark will be positive from the outside draw aboard Peltzer to sit up on the speed. The likes of Harmony Rose, Lion's Roar and Here To Shock shouldn't be far away. Tactics aboard The Elanora and Prime Star will be interesting from out wide. The Elanora went back in the Hobartville over 1400m. Barrier 11 looks awkward for Prime Star and Jean Van Overmeire may ride for a bit of luck.
