Bolt shines bright, wins another gold in Olympic 100 (Yahoo Sports)

If there were any doubts, it took less than 10 seconds – 9.81, to be exact – for Usain Bolt to erase them. The 6-foot-5 sprinter/celebrity overcame his typically slow unfurling from the blocks, gradually worked up speed, caught American Justin Gatlin with 40 meters left and was celebrating – pointing at his chest with his thumb – before he crossed the finish line. Bolt beat Gatlin, who was greeted by the fans with raucous boos, by .08 seconds.
