Big guns to battle at 100m Roman showdown

World 100 metres record holder Asafa Powell will take on Olympic champions Justin Gatlin and Shawn Crawford as well as world sprint champion Kim Collins in a world-class 100m in Rome next month.

Powell, who set the new mark of 9.77 seconds in Athens earlier this month, will throw down the gauntlet to Olympic sprint champion Gatlin at the Golden League meet on July 8 just a month prior to the World Championships in Helsinki.
