CITY of York Athletics Club ace Richard Buck has booked his place in the final of the 400 metres at the Aviva 2012 Olympic Trials.

Buck was fourth in his heat in Birmingham but his time of 46.31 seconds was enough to earn him a slot in Sunday's final.

Nigel Levine won Buck's race in 45.91 seconds, while the other heat winners were Rob Tobin (45.77), Martyn Rooney (46.24) and Conrad Williams (46.15).
