LONDON -- Recent Stanford graduate Amaechi Morton, representing Nigeria, easily advanced after his opening-round race in the 400-meter hurdles as Olympic track and field got under way Friday.
Meanwhile, Jessica Ennis gave British fans a reason to cheer, setting a meet a record with the fastest 100-meter hurdles ever run in the heptathlon.
Morton, running for his mother's homeland, ran 49.34 seconds to qualify for Saturday's semifinals. Americans Kerron Clement, Angelo Taylor and Michael Tinsley also all advanced.
Thousands of fans waved the Union flag and gave Ennis a huge ovation when she was introduced for the last heat of the opening event and she didn't disappoint, winning it in 12.54 seconds to beat the old Olympic heptathlon mark of 12.62 run by Eunice Barber of France in 2005.
She held her hands over her face in disbelief as the time showed on the big screen, realizing she had sliced one-quarter of a second off her best time. Her time Friday equaled the gold-medal performance in the 100 hurdles at the 2008 Beijing Olympics.
The seven-event heptathlon concludes Saturday.
All of the top entries in men's shot put qualifying moved into Friday evening's final, led by Americans Reese Hoffa, Ryan Whiting and Christian Cantwell. Hoffa had the top mark in the prelims with a throw of 70 feet, 1 inch. Also advancing was defending gold medalist Tomasz Majewski of Poland.
