Sublime Caster Semenya sticks to the script

Caster Semenya won the Olympic title in the 800m Saturday with no-one close to challenging her, a result that will only stoke the complex debate over whether women with much higher levels of testosterone than normal should be allowed to compete unchecked.
Semenya, of South Africa, won her first Olympic gold in a personal-best of 1 minute, 55.28 seconds, a national record and one of the top 20 times ever in the two-lap race.
