BEIJING, Aug. 17 (UPI) -- Sunday's Olympic highlights:
-- Michael Phelps, who came to Beijing as a renowned swimmer, headed home as a legendary one. He won his eighth gold medal of the Olympics, one more than the record held by Mark Spitz since 1972, and ran his career gold total to 14. His final triumph came in the 400-meter medley relay, on which he swam the fastest butterfly split in history.
-- The torrent of action around the Olympic city provided one of the busiest days in the history of the Games. Athletes from 33 nations won medals. China had eight victories, one of them from Guo Jingjing -- who established a record for most Olympic diving gold medals ever with six.
-- China finished the day with 35 gold medals, 16 more than the United States. The Americans clung to the overall medal lead 65-61. Britain won eight golds during the weekend and has 11 for the Olympics, equaling its largest total in the last 88 years.
-- Led by Shelly-Ann Fraser, Jamaicans swept the medals in the women's 100-meter dash. That came a day after Usain Bolt won the men's 100. Although the United States won a dozen medals Sunday, none of them came in track and field.
-- Rafael Nadal added the Olympic gold medal to the title he won at Wimbledon, yet another honor for the man who is about to become the No. 1 tennis player in the world.
-- The American boxing team was reduced to one fighter. Heavyweight Deontay Wilder reached the semifinals on a judging tie-breaker, ensuring at least a bronze medal and saving the boxing program from acute embarrassment.
