We're down to the last twelve in this year's William Hill Greyhound Derby and Aero Nemesis, Crokers Champ and Mind The Net are the three disputing favouritism ahead of the semi-finals.

Racing Post greyhound expert Jonathan Kay joins Mark Walton to look ahead to the action at Wimbledon, starting with a re-assessment of the Outright Betting.

Jonathan then looks ahead to Saturday evening, offering his one-two-three predictions in the two semis and opening heats of the William Hill Derby Plate and the William Hill Champion Hurdle.

Enjoy.
