Zhang Anda shocked world number three Zhao Xintong with a thrilling 6-5 victory by potting a respotted black ball in round one of the China Open. Zhang, who was down 3-0 in frames, fought back to eventually lead 5-4. However, last year's world champion Zhao forced a deciding frame that ended in dramatic fashion.\n\nZhang, ranked 19th in the world, was in control at 57-0 up, but Zhao fought back to lead with both players on the black.

The black was eventually potted by Zhang to force a respot - used as a tie-breaker when a frame ends with the scores level - with the 34-year-old prevailing. He will now face England's Chris Wakelin.\n\nWorld number five John Higgins also lost in the first round after he was defeated 6-4 by 2015 world champion Stuart Bingham.
