New Zealand's Zoi Sadowski-Synnott retained her slopestyle title at the FIS Snowboard and Freeski World Championships in Aspen, Colorado on Friday, but she had to dig deep to do so.<br /><br />Jamie Anderson of the United States set the early standard with a first run worth 81.10 points and that looked like being enough to take the gold medal after Sadowski-Synnott took a painful tumble in her first effort and could only score 47.06 poits in her second.<br /><br />But in the final round, the 20 year-old gold medalist from two years ago in Utah put it all together and a brillant run scoring 85.95 points meant the title was hers again.<br /><br />Double Olympic champion Anderson had to settle for the silver, with Tess Coady of Australia picking up the bronze, her first top level medal in the sport.
