- Tommy Robredo's latest five-set fight-back came with controversy on Thursday as a fan in the notoriously boisterous US Open crowd intervened at a crucial point.

The 16th-seeded Spaniard was favoured to get past Simone Bolelli, but the Italian took the first two sets and was eyeing an upset before Robredo rallied for a 5-7, 6-7 (5/7), 6-4, 6-3, 6-2 triumph.

The controversy erupted in the third set, as Robredo gained a break after Bolelli stopped playing when someone in the crowd called "out".

The umpire ruled that Bolelli must concede the point, although the Italian wanted to play a let.

"I think the umpire made a very big mistake," Bolelli said. Robredo called it "very bad luck for Bolelli".
