Rafael Nadal took on Louisiana-born Ryan Harrison in the opening-day main event at this year's US Open.
Second seed and 12-time Grand Slam winner Nadal began the week as the favourite to win the men's title at Flushing Meadows.
The 27-year-old Spaniard was unbeaten on hardcourts in 2013, having won 15 consecutive matches and picking up titles in Indian Wells, Montreal and Cincinnati.
Meanwhile, 21-year-old Harrison, who was ranked 97th in the ATP World Rankings, had failed to progress beyond the final-32 stages in his last three tournaments on this surface.
Would there be an upset, or would Nadal's sensational run continue? Find out how the match unfolded below with Sports Mole's blow-by-blow text updates.
Good evening. One male seed has already fallen today. British number three Dan Evans, ranked 179th in the world, overcame 11th seed Kei Nishikori 6-4 6-4 6-2. That result was certainly a shock, but its place on the back pages would be in severe doubt if Nadal were to lose to Harrison.
PREDICTION: I'm going to stick my neck on the line and say that WON'T happen. I fully expect Rafa to progress in straight sets.
