CARSON (California), May 23: Former Olympic 100 metres champion Maurice Greene suffered a shock defeat in the Adidas Track Classic at the Home Depot Center on Sunday in a race marred by equipment problems and two false starts. Greene finished fourth in a race won by fellow American Leonard Scott, who recorded an impressive 10.03 seconds running into a stiff headwind.

Olympic champion Jeremy Wariner won the men’s 400 metres in 44.53 seconds with key rival and Olympic silver medallist Otis Harris trailing in last after appearing to be unsettled by a false start.

Olympic gold medallist Veronica Campbell powered to victory in the women’s 100 metres in 10.96 seconds, the fastest time in the world this year. The 23-year-old Jamaican won gold in the 200 metres in Athens plus bronze in the 100 metres.

Olympic champion Joanna Hayes won the women’s 100 metres hurdles in a time of 12.64 seconds, a world best mark for 2005.

Olympic silver medallist Bernard Lagat produced the fastest time by an American this year in winning the men’s 1500 metres.

The 30-year-old Lagat, who won his Olympic medal for Kenya, became a US citizen just under two months ago.
