SAN FRANCISCO, Sept. 29, 2013 /PRNewswire/ -- It has been 50 years since Alcatraz was home to America's most notorious criminals. This year, for the fourth and final time, sixty-four of the toughest international street ballers gathered on one of the world's most iconic and recognizable locations for the Red Bull King of the Rock Finals before the one-on-one basketball competition heads to Taiwan in 2014. The talent pool was better than ever, as half of the final eight players were from outside of the U.S. (Photo: http://photos.prnewswire.com/prnh/20130929/LA88451-a) (Photo: http://photos.prnewswire.com/prnh/20130929/LA88451-b) (Photo: http://photos.prnewswire.com/prnh/20130929/LA88451-c) The one-on-one basketball tournament brought 64 of the best players from 19 countries to face off in one of the most notorious locations on earth. Amidst the crumbling walls and the eerily lit cell house, in front of hundreds of spectators, including guest host, basketball All-Star Blake Griffin, the players battled each other on the cracked and cold concrete in The Yard. But there can be only one king, and at the end of the night it was Tarron "The Beast" Williams who was left standing to take the trophy. The 36-year-old from Inglewood, Calif., who got his nickname from Baron Davis, overcame severe leg cramps suffered in the semifinals to shut down Sergio de la Fuente from Spain, 6-0, and left The Rock as The Champ. "It was a tough battle," said Williams. "I was starting to cramp up, but I had to keep going and not let my fans down. I'm proud of myself. I trained hard, rode my bike to work and played basketball outside late at night, sometimes with no lights." The 64 players relied on endurance and composure as they battled through fierce competition, cold temperatures and the worn concrete courts. With four half courts in simultaneous game play, the action was intense and almost nonstop.
