Coleman paid tribute to his teammate Gatlin, 37, who first won the world championships in 2005 and claimed the Olympic title in 2004.

"Justin Gatlin is a great guy and great competitor. I remember watching him back in 2004 when I was eight years old and to think all these years later I could come and win gold too is a great feeling," he said.

American DeAnna Price hurled a winning mark of 77.54 meters from her third round effort to take the hammer title. Joanna Fiodorow of Poland took the silver at 76.35, while China's Wang Zheng, silver medalist at the London worlds two years ago, finished third at 74.76.

The United States set the 4X400 meters mixed relay world record in 3:12.42, beating the previous world best time of 3:13.20 registered three years ago in an American local event in Eugene. The mixed relay was included for the first time into the athletics world championships.

"It was fun. The first time I saw it on TV, it looked funny. You feel much closer to your teammates and we are working together," said fourth leg runner Obi Igbokwe of the United States.

Tajay Gayle created history by taking Jamaica's first men's long jump gold medal at the world championships as he stunned a deep field to win in 8.69m. The 23-year-old twice improved his personal best by a total of 37 centimeters, starting the competition with a big jump of 8.46m which was good enough to secure his victory.

Olympic champion Jeff Henderson of the United States bagged a silver at 8.39 and the highly favored Juan Miguel Echevarria of Cuba finished third at 8.34.
