BEIJING (AP) — Forgive Dafne Schippers for being dazed and dizzy.Running the fastest 200 meters at sea level in more than a quarter century does that to you. What stupefies her even more is the realization where she is now and where she came from in barely a year."Give me some time to myself to think about what is happening to me," Schippers said Friday after winning her first world title and adding it to her 100-meter silver to become one of the world's top sprinters a year ahead of the Olympics.After clawing back in a race at the Bird's Nest and winning with a dip to the line, the 23-year-old Schippers fell to the track, holding her hand to her head in disbelief.After all, early last year she was still committed to spending her career as a little-known athlete excelling at the seven-event heptathlon, which is appreciated by few outside a tight group of cognoscenti.
