Top seed Novak Djokovic secured a 7-6 (7-2) 6-3 6-1 victory over American outsider Bobby Reynolds to books his spot in the third round of Wimbledon.
The 2011 champion was pushed all the way in the first set but once he had gained the advantage, his opponent was unable to keep up with him.
Reynolds' heavy serve started to desert him after the opening set and Djokovic was an easy winner in the end, taking just an hour and 54 minutes to wrap up the victory.
Djokovic's win made it the worst Wimbledon for America's men for more than a century.
There were 11 US entrants in the men's singles draw but, after Reynolds' defeat, none are left going into the third round for the first time since 1912.
Reynolds had the toughest task of the lot and he performed admirably against Djokovic, earning the support of the crowd for his dogged resistance in the early stages.
Djokovic was not at his best but he would have been more than happy with a straight-sets win after yesterday's drama ended with Roger Federer joining Rafael Nadal in crashing out of the tournament.
Reynolds, a qualifier ranked 156th, earned a huge cheer when he set up a first-set tie-break but Djokovic took control straight away to close out the set with ease.
The only glimmer of hope for Reynolds came at 1-0 in the second set when he had a routine smash to go 0-40 on the Djokovic serve up but shanked it over the baseline. The crowd sighed, Djokovic held and then finally took his ninth break point.
The longer the match went on, the better the Serbian played, and he eventually wrapped up victory with a neat volley despite taking only four of 18 break points.
