Robert E. Lee senior Sean Holston made a splashing debut in the 500 meter dash in Friday\'s F.I.T. Invitational held at Prince George Sports and Learning Complex in Landover, Maryland. The defending 300 meter state champion posted the fastest time in the country this season and 17th fastest 500 meter time in U.S. prep history with a 1:03.93 clocking. Time has to rank fairly highly among top all-time unbanked 500 meter times. Holston blitzed the new event from the start with a 36 second first 300 meters and dipping under 50 seconds at 400 meters. Complete results are posted with more to come from F.I.T. on Saturday including elites, more highlights, meet summary, photos, and video clips.
