World and Olympic champion Jeremy Wariner put young pretender LaShawn Merritt in his place in an excellent 400 meters. Merritt has been pushing his fellow American all season and ran strongly to lead off the final bend. Wariner, however, continued with his smooth, fluid stride while the big 21-year-old a lane inside him tightened up over the final 30 meters. (WCSN, WCSN.com)
