He was accused of dragging his trail leg during the second, or "step" portion of the event. He had several jumps over 17.37 metres and at least one estimated to be just under 17.60 metres (Olympic record was 17.39), but after each of those jumps, and sometimes with a few seconds' hesitation, a judge's red flag indicated a foul. He won the silver medal at the 1978 Commonwealth Games with 16.93 and was third in 1979 IAAF World Cup with 16.76. His personal best result was 17.09.
