Sailing: High winds on San Francisco Bay forced a postponement of 34th America’s Cup sailing on Tuesday, delaying a potential final showdown between series leader Emirates Team New Zealand and defender Oracle Team USA. A seasonally strong out-flowing tide on San Francisco Bay running against incoming wind created conditions that exceeded safety limits set for the delicate 72-foot catamarans. A proposal by Oracle to increase the wind limits for racing was rejected by New Zealand. Oracle’s performance over the weekend suggests its AC72 is faster than New Zealand’s in heavy winds, some observers believe.

Snooker: Both Stephen Maguire and Stuart Bingham suffered shock first-round exits at the Shanghai Masters as Xiao Guodong and Kyren Wilson produced stunning displays yesterday. Xiao gave the home fans something to cheer with a 5-2 win over Maguire – but Wilson’s was the performance of the day as the 21-year-old marked his first appearance at the final stages of a ranking event by beating Bingham 5-1. He could even have added a 147 break in frame four, but missed the 13th black after making 97. That was more than enough for a four-frame lead and though Bingham pulled one back in the next, a run of 54 in frame six sealed Wilson’s win.

Tennis: John Tomic, father and coach of Australian tennis player Bernard Tomic, has denied assaulting his son’s training partner in a Madrid street in May but said he now wished he really had punched the Frenchman. The 49-year-old was sentenced to eight months in prison by a Spanish court earlier this month for head-butting Thomas Drouet in the face and breaking his nose. Tomic denied the charges in a Spanish court, saying he acted in self-defence, and did not have to serve jail time because his sentence was less than two years.
