Andy Roddick withstood a fierce onslaught from 12th seed Paradorn Srichaphan to keep alive his Wimbledon dreams with a 6-4 3-6 6-3 6-2 victory in the fourth round today.
The fifth-seeded American had to dig deep for victory and his first Wimbledon quarter-final as the Thai put in an inspired display on Centre Court.
Roddick, who had been broken just once in his first three matches, appeared to be hurtling towards victory as he fired six aces on his way to wrapping up a rain-interrupted first set in 23 minutes.
But he came unstuck in the second as Paradorn stunned the favourite with a superb display of power hitting from the baseline.
Having saved numerous break-point opportunities in the first two games of the third, Roddick rediscovered his winning touch to seal the third set with a 124 mph ace - his 11th of the match.
The 20-year-old secured the win with a fizzing forehand crosscourt winner to set up a last eight meeting with either Belarussian Max Mirnyi or doubles specialist Jonas Bjorkman of Sweden.
