LONDON -- Be it a gold medal or a souvenir from a record relay run, Usain Bolt always gets what he wants at the Olympics.
The Jamaican will leave London a perfect 3 for 3 -- three events, three victories -- just the way he departed Beijing four years ago.
About even with the last U.S. runner when he got the baton for the anchor leg of the 4x100-meter relay, Bolt steadily pulled away down the stretch, gritting his teeth and leaning at the line to cap his perfect Summer Games by leading Jamaica to the title in a world-record 36.84 seconds Saturday night.
After crossing the line, Bolt pleaded with an official to let him keep the yellow baton he was clutching. But the answer was "No," and Bolt handed it over while some nearby spectators booed. About 40 minutes later, that same official approached Bolt and returned the stick. Bolt responded with a bow of thanks and kissed the baton.
One more possession to help him remember his week at 80,000-seat Olympic Stadium, where any mention of Bolt's name drew raucous cheers, countless camera flashes and chants of "Usain!"
"It's amazing. It's been wonderful," Bolt said in an interview shown on the scoreboard.
Talking to the spectators, he said: "You guys are wonderful. Thanks for the support. I love you guys."
Bolt added the relay gold to the ones he earned in the 100 in 9.63 seconds last Sunday -- the second-fastest time in history -- and the 200 in 19.32 on Thursday.
The U.S. quartet of Trell Kimmons, Justin Gatlin, Tyson Gay, and Ryan Bailey got the silver in 37.04.
