Former Vol Justin Gatlin advanced from the prelims to the semifinals in the men's 60m dash. He did so with a time of 6.64 that won heat seven.
In the women's 3000 meters, ex-Lady Vol Jackie Areson moved out of the qualifying round to the final. Her season-best 9:12.62 readout left her fourth in section one and eighth-fastest of the qualifiers for Sunday's final.
It was a mixed bag in the women's 800m prelims. Erica Moore finished second in section three in 2:00.24 to advance to a Sunday final as the second-fastest qualifier. Phoebe Wright, on the other hand, led her race through 400 meters but could not hold on, settling for fifth place in section one in 2:03.11.
The only non-American Tennessee product in action on day one was Patricia Hall. The Jamaican sprinter advanced out the first round of the women's 400 meters with a 52.99 readout but saw her road come to an end in that event when she checked in third in heat three of the semifinals at 53.21.
Aries Merritt (men's 60m hurdles) and Tianna Madison (women's 60m dash) will compete for the first time on Saturday, representing the United States in first-round races. Gatlin has a semifinal race and potentially a final as well on Saturday.
