Arkansan Michael Tinsley has qualified to run in the semifinals in the 400m hurdles.
Tinsley ran in heat 2 of the qualifying race this morning in London and came in first with a time of 49.13.
Two other Americans also qualified to run in the semifinals as follows:
Kerron Clement (finished 2nd with 48:48)
Angelo Taylor (finished 1st with 49:29)
Tinsley is a Little Rock native who went to high school at Pulaski Robinson.
He won the 400m hurdles event at the 2012 Olympic Trials with a time of 48.33 to earn a spot on the U.S. Olympic team.
NBC Sports is airing other track and field events in its coverage today and into the weekend but there's no guarantee that coverage will include Tinsley's next race.
