Berlin, Aug 23 (DPA) Usain Bolt reached another athletics milestone at the World Championships Saturday but a Polish hammer thrower stole the world record from him.

Bolt became the first man to claim sprint trebles at Olympics and world championships when he helped Jamaica win the 4x100 metres relay.

He then accepted the blame that the winning time was only the second best in race history, saying 'I am really tired.'

Instead, Poland's Anita Wlodarczyk got the US$100,000 world record bonus for a hammer throw of 77.96m.

The men's relay completed another overwhelming sprint win of the Jamaicans over the United States, the final score 5-1 one year after a 5-0 whitewash at the Beijing Olympics. The only US win was from Allyson Felix in the women's 200.

Jamaica won both relays in the absence of the US whose men's team was disqualified and women's team saw Muna Lee injured after an awkward baton exchange.

Steve Mullings, Michael Frater, Bolt and Asafa Powell claimed the gold in 37.31 seconds, missing their Olympic mark of 37.10 seconds. Trinidad and Tobago came second with 37.62 and Britain was third with 38.02 seconds.

Bolt won the individual races with amazing world records of 9.58 and 19.19 seconds, respectively, and with the relay prize money took home 340,000 dollars - and a chunk of the Berlin Wall to be given to him on Sunday by local organizers.

He is the third man to get triple sprint gold at the worlds, following Americans Maurice Greene (1999) and Tyson Gay (2007), but no one has ever achieved it at the worlds and Olympics.

'Winning three gold medals in Berlin is wonderful. I am proud of myself,' said the 23-year-old phenomenon.

'I had great championships and got two records. I came here, did my best, although I was not in my best shape ... I didn't say I wasn't fast enough. The difficulty was the many rounds.'

Jamaica's Simone Facey, 100m champ Shelly-Ann Fraser, Aileen Bailey and Kerron Stewart won the women's gold in 42.06 seconds. Bahamas (42.29) took the silver while the full house roared the German team to bronze in 42.87.

Victory was sweet for Jamaica which had dropped the baton in the Beijing final, with Fraser saying: 'We wanted to make sure we were safe and that we finished.
