Roger Federer put a shaky start behind him to easily dispatch Yen-Hsun Lu in the first-round of Wimbledon.
The five-time champion, who had not played competitively since his French Open win, showed signs of rust in the opening set before securing a 7-5 6-3 6-2 win.
The 14-time grand slam winner failed to convert four break point opportunities in the fourth game of the match before losing his own serve in the next game.
Federer broke back with the aid of a fortunate net cord and then went on to win a tough opening set.
Timing
It was a more confident Federer that walked out for the start of the second set and he achieved another break in fine style.
A winning backhand pass down the line in the fourth game showed that he had found his trademark timing.
Lu did manage to win two break-back points in the seventh game of the set but could not convert them and fell two sets behind shortly after.
The player from Chinese Tapei again lost his serve at the beginning of the third set, dumping a backhand volley into the net to hand the Swiss a decisive lead.
Federer took a tumble in the fourth game and the crowd held it's breath as he seemed to turn his ankle but luckily he was uninjured.
A running forehand broke Lu for a fifth time in the match and rounded off the straight sets victory in one hour and 44 minutes.
Federer, who was given the chance to open on Centre Court in the absence of Rafael Nadal, paid tribute to the Wimbledon organisers after the match.
"I feel very privileged that they gave me the chance to do it again. There's less pressure going into Wimbledon not being defending champion," he said.
"I played really well and my opponent was good. I could see why he had beaten so many good opponents."
