The rosters for the United States and Jamaican teams have been announced for Saturday's Penn Relays USA vs. the World competition.
Big names include Shawn Crawford, Justin Gatlin, Allyson Felix and Lauryn Williams for the United States, and Asafa Powell, Nesta Carter, Aleen Bailey and Shelley-Ann Fraser for Jamaica.
Philadelphia natives and West Catholic alumnae Nicole Leach and LaTavia Thomas are also on the U.S. squad, as part of the women's 4x400-meter relay team.
The U.S. roster I was went was broken down by race, but the Jamaican roster was not. So I'll just give you what I was sent, with some big names on Jamaica's team in bold:
Sherone Simpson, Davita Prendergast, Kalise Spencer, Christine Day, Kerron Stewart, Melanie Walker, Novlene Williams, Kenia Sinclair, Aleen Bailey, Simone Facey, Shelly-Ann Fraser, Michael Frater, Nesta Carter, Asafa Powell, Steve Mullings, Ramone McKenzie, Duwayne Barrett, Sanjay Ayre, Lerone Clarke, Michael Mason
