LONDON (AP) Kendra Harrison of the United States has broken a 28-year world record in the 100-meters hurdles by running 12.20 seconds at the London Diamond League meet.
The confidence-boosting run comes after the 23-year-old American failed to make the U.S. team for the Olympics in Rio de Janeiro next month.
Harrison says ''not making the Olympic team I was really upset and I wanted to come out here and do what I know what I could have done'' in Rio.
Speaking on the Olympic Stadium track in London, Harrison said: ''I was coming out here with just vengeance to show these girls what I have.''
Harrison finished ahead of compatriots Brianna Rollins and Kristi Castlin to surpass Yordanka Donkova's previous mark of 12.21 set in August 1988.
