BERLIN (AP) Dawn Harper-Nelson led an American 1-2 in the women's 100-meter hurdles and compatriot Candyce McGrone claimed victory in the 100 sprint at the ISTAF athletics meet Sunday.
Harper-Nelson, the 2008 Olympic champion, was keen to bounce back after clattering into a hurdle and falling in her semifinal at the world championships in Beijing. She clocked 12.82 to edge Sharika Nelvis by two hundredths of a second. European champion Tiffany Porter of Britain was third at the IAAF Word Challenge meet.
''It was very difficult for me to recover after Beijing and my fall. I felt physically OK but mentally it was tough,'' Harper-Nelson said. ''I prayed a lot and it seemed to help. You know, I love hurdles and always want to show the best of me.''
McGrone won the sprint in 11.11, beating Marie-Josee Ta Lou of Ivory Coast by one tenth of a second and fellow American Barbara Pierre by two tenths.
''It's my first victory this season, very precious,'' said McGrone, who hoped it would give her a ''positive kick'' for ''the upcoming season when I want to fight for the spot in the Olympic team.''
Jeneba Tarmoh of the U.S. was fourth, while Michelle-Lee Ahye of Trinidad and Tobago hobbled over the line after pulling up with an injury.
Kim Collins of Saint Kitts and Nevis won the men's 100 in 10.13, edging American Isiah Young by four hundredths of a second.
''I really needed this to boost my self-confidence after what happened in China,'' said Collins, the 2003 world champion, who failed to emerge from his heat at the Worlds. ''My body and soul needed to recover from it.''
Andrew Riley of Jamaica celebrated his 27th birthday by winning the 110 hurdles in 13.40, ahead of Shane Brathwaite of Barbados.

Lynsey Sharp of Britain ran a personal best of 1:57.71 to beat German champion Fabienne Kohlmann and world champion Marina Arzamasova in the women's 800.
