Tennis: Spain's Albert Montanes became the first man into the last 16 of the US Open after Japan's Kei Nishikori was forced to retire from their third round match at Flushing Meadows.
Montanes, the 21st seed, had won the first set 6-2 and was leading 2-1 in the second when Nishikori indicated he was unable to continue with a groin injury.
Nishikori, who came through three matches in qualifying just to reach the main draw, was possibly suffering the effects of his second round win over 11th seed Marin Cilic.
The 20-year-old beat Cilic 5-7 7-6 3-6 7-6 6-1 in a match lasting just a minute shy of five hours in sweltering conditions in New York.
