The nation's top two ranked 800m runners race for the first time in Seattle: defending champion Christina Aragon and World Youth champion Sammy Watson. Aragon is already an Olympic Trials qualifier in the 1500m with her 4:09.27 best; Watson has run 2:03.06 for 800m -- so close to the 2:03.0 standard! Watch what happens when they race for the first time.
