Second seed Andre Agassi set up a second round clash with Britain's Jamie Delgado after a surprisingly comfortable victory over Holland's Peter Wessels.
Agassi was made to work hard in the opening stages but once he took the first set on a tie-break there was never any doubt about the outcome.
The 1992 champion needed less than two hours to wrap up a 7-6 (7-1) 6-4 6-4 victory on Centre Court and looked to have put his stunning French Open exit firmly behind him.
Agassi has not played a competitive match since that amazing day at Roland Garros when his four-set defeat to France's Sebastien Grosjean in the quarter-finals was blamed on the presence of former President Bill Clinton in the crowd.
During the first set at least Wessels looked capable of pushing the flamboyant American all the way as the first 12 games went with serve, the Dutchman's powerful serve never threatened by probably the best returner in the game.
But it all went wrong for Wessels in the tie-break as he failed to win a single point on his own serve as Agassi took it 7-1.
Wessels appeared understandably deflated by surrendering the first set so tamely and it was no surprise when he was broken in the opening game of the second set, Agassi converting his first break point of the match with a backhand winner down the line.
Wessels, who had beaten US Open champion Marat Safin on his way to the quarter-finals of Queen's recently, could find no way to get back on level terms by breaking Agassi's serve and his frustration manifested itself with a series of complaints over debatable line calls.
The umpire remained unmoved however and Agassi served out to take the second set 6-4 and one more break of serve was enough to take the third set by the same score and complete a highly satisfactory afternoon.
