Olympic gold medallist Dawn Harper leads a strong field announced on Wednesday for the women\'s 50m hurdles at next month\'s US Open indoor athletics meeting at Madison Square Garden. USA Track and Field said that Harper would be joined in the event by two-time defending world indoor champion Lolo Jones, USA Indoor and Outdoor champion Kellie Wells and British national record-holder Tiffany Ofili Porter. The showdown adds to previously announced stars Jesse Williams, Christian Cantwell, Adam Nelson, Bernard Lagat, Veronica Campbell-Brown, Asafa Powell, David Oliver and Jenn Suhr, all seeking to get their Olympic-season campaigns off to flying starts. The famed arena in Manhattan will host the first edition of the US Open on January 28 as the first event of USA Track and Field\'s Visa Championship Series. Meanwhile the Millrose Games, the indoor meeting held at Madison Square Garden since 1914, have been moved by organizers to the more modern Armory Track and Field Center in New York on February 11.
