Input: (CNN) -- Shelly-Ann Fraser-Pryce kept her tag of the fastest woman in the world with a performance as dominating as her Jamaican male counterpart Usain Bolt 24 hours earlier to claim the 100m title at the world championships Monday. The diminutive 1.52m tall sprinter recovered from an indifferent start to drive through the line in 10.71 seconds, the fastest time of the year. After a build-up dominated by doping scandals involving Trinidad and Tobago's Kelly-Ann Baptiste and her own teammate Veronica Campbell-Brown, who would both have been medal contenders, Fraser-Pryce reminded everyone of her formidable talent. The double Olympic champion and winner of the world title in 2009 shrugged off a minor injury problem to win from Ivorian Murielle Ahoure (10.93), with defending champion Carmelita Jeter of the United States taking the bronze (10.94).Shelly-Ann Fraser-Pryce wins women's 100m at world championshipsDiminutive Jamaican runs fastest time of the seasonBuild up to event dominated by positive doping testsChristine Ohuruogu dips for 400m gold
