Representing a nation with a population of less than half a million, Muller brutally exposed the weakness of Roddick’s backhand and repelled his 150mph serve with a remarkable 65 outright winners.
Having trailed 5-2 in the first set, Muller won the respective tie-breaks 7-4, 10-8 and 7-1 against the man with the hardest serve in the sport’s history.
In contrast to Roddick, men’s top seed Roger Federer picked up where he left off last year, starting his title defence with a ruthless first-round defeat of Czech Ivo Minar.
A year ago, Federer crushed Lleyton Hewitt in the final and the Swiss top seed’s 61-minute, 6-1, 6-1, 6-1 victory over Minar sent out an ominous warning to those who covet his US crown.
Women’s second seed Lindsay Davenport, third seed Amelie Mauresmo and French Open champion Justine Henin-Hardenne also advanced to the second round without dropping a set.
Federer had played only one tournament since completing a hat trick of Wimbledon titles in July but looked in peak form from the start against Minar, lashing forehand winners at will.
World number one Davenport had to work hard for a 6-4, 6-4 win over a determined Li Na of China in the first evening session match.
Together with Belgian Kim Clijsters, former world number one Mauresmo is the most-gifted women’s player still looking for a Grand Slam title and the Frenchwoman was too strong for Roberta Vinci, beating the Italian 6-3, 6-2.
Mauresmo faces a tricky second-round opponent, however, in Bulgarian 16-year-old Sesil Karatantcheva.
Seventh seed Henin-Hardenne ensured there was no repeat of her shock first round exit at Wimbledon in June with an impressive 6-3, 6-0 win over Czech Zuzana Ondraskova.
Russian sixth seed Elena Dementieva, the runner-up last year, recovered from a slow start to quell another Czech, Lucie Safarova, 7-5, 6-3.
Henman, the 12th seed, slumped to a dismal 6-4, 6-2, 6-2 defeat to Spain’s Fernando Verdasco.
The loss means the 30-year-old, who was hampered by a painful back injury, will tumble down the men’s rankings because he reached the last four here last year.
Rusedski, the 28th seed, was beaten in three sets by in-form American James Blake, the winner at New Haven on Sunday.
Murray bravely overcame Romanian Andrei Pavel 6-3, 3-6, 3-6, 6-1, 6-4, having vomited apparently from exhaustion early in the fifth set.
Pavel, ranked 83 places above the 18-year-old, was later penalised a point for swearing at the umpire following an over-rule.
