Newly crowned Olympic champions Shelly-Ann Fraser-Pryce and Sanya Richards-Ross both qualified on Tuesday for the final of the 200m in their quest for a second sprint gold at the London Games. American Richards-Ross, who won the 400m title on Sunday, timed the fastest qualifying time from the three semi-finals, in 22.30sec. \"I\'m having a really good time, I have already won a gold medal so there is a lot of weight off my shoulders,\" said Richards-Ross. \"That has been my dream to be announced as an Olympic champion and every time I hear it just makes me want to cry.\" Jamaica\'s Fraser-Pryce, crowned champion of the 100m on Saturday, was second in the same semi after dominating the opening 150m and easing up at the line to clock 22.34. In what promises to be a thrilling final on Wednesday evening, the double-chasing pair will race against Jamaican Veronica Campbell-Brown, who is seeking a third consecutive 200m gold. \"I am happy,\" said Campbell-Brown, after posting an impressive 22.32sec to win her race. \"I have a lot of experience, I know what to expect. Tomorrow night we know that it will be an extremely difficult event. My objective is just to stay focused - and run my heart out.\" Also competing will be American duo Carmelita Jeter, pipped to the 100m gold by Fraser-Pryce, and a three-time world champion in the distance, Allyson Felix. \"It has been a long time coming. I feel I am ready to put a race together,\" said Felix, who ran a personal best and world-leading time of 21.69sec at the US Olympic trials, the fastest for 14 years. \"I think if I put a good race together I\'ll run a fast time.\" Making up the final will be Ivory Coast\'s Murielle Ahoure, Trinidad and Tobago\'s Semoy Hackett and France\'s Myriam Soumare. The first woman to do the 100-200m double was legendary Dutch runner Fanny Blankers-Koen, who performed the feat in London in 1948.
