Justin Gatlin won what could be an early Olympic 100m preview at a meet in Gainesville, Florida, on Saturday.
Gatlin, the 2004 Olympic gold medalist and 2017 World champion, clocked 9.98 seconds at the Tom Jones Memorial Invitational at the University of Florida. Full results are here.
Gatlin, who in 2016 became the oldest man to win an Olympic 100m medal at age 34 (silver), broke 10 seconds in each of his first two meets this season.
In Tokyo, he can become the oldest man ever to earn an Olympic medal in any event on the track, according to Olympedia.
