South African teenager Caster Semenya won the women’s 800 meters gold medal at the World Athletics Championships in Berlin, just hours after the sport’s governing body asked for the 18-year-old’s gender to be verified. Semenya crushed her rivals by streaking away to secure victory in a time of one minute 55.45 seconds — the best time in the world this year. Defending champion Janeth Jepkosgei of Kenya took the silver with Briton Jennifer Meadows claiming bronze.
