Rafael Nadal looked in ominously good form as the Spaniard brushed aside Australian John Millman in the first round of Wimbledon.
Nadal is bidding to win his 16th grand slam title at the All England Club following his 10th French Open triumph last month, and on this evidence he would appear more than capable after beating Millman 6-1 6-3 6-2.
The world number two will next face American Donald Young, who booked his place in the second round after opponent Denis Istomin retired injured.
Nadal has endured his own physical problems on grass, having missed Wimbledon last year due to a wrist problem, and he has struggled with the effects of the faster surface on his knees.
But Millman found little sign of weakness in the 31-year-old, who hit 33 winners en route to victory in an hour and 46 minutes.
Millman, ranked 137th in the world, pushed Dominic Thiem to five sets at the US Open last year. But while playing his part in some thrilling exchanges on Court One, an upset never looked likely.
In what was his 50th match here, Nadal broke the Australian's serve three times in the opening set and then again early in the second when the best rally of the match ended with him whipping a winning forehand down the line.
Millman offered some resistance by breaking back for 3-2 but Nadal would not be deterred as another booming forehand left his opponent sprawled on the floor, face planted into the turf.
Nadal was handed a time violation at the start of the third but nothing could delay his progress as three more scintillating forehands in the final game rounded off a thoroughly convincing performance.
Andy Murray's Wimbledon prospects look a whole lot brighter after a confident first-round win over lucky loser Alexander Bublik.
The build-up to the defence of Murray's title had been dominated by concerns over a hip injury and the world number one's poor form in 2017.
But the Murray who lost so woefully to Jordan Thompson in the opening round at Queen's Club three weeks ago was nowhere to be seen.
The Scot continued to limp between points, as he had since resuming practice on Friday, but movement was just one of the things he did well in a 6-1 6-4 6-2 victory.
Cameron Norrie's first match at Wimbledon ended in defeat as the British wild card was outclassed by 12th seed Jo-Wilfried Tsonga.
Norrie has taken time out from a sociology degree in Texas to play professional tennis this year but the 21-year-old was given a lesson by Tsonga, who cruised to a 6-3 6-2 6-2 victory.
Tsonga will now face either Lu Yen-hsun of Taiwan or Italian qualifier Simone Bolelli in the second round.
Norrie was born in South Africa, raised in New Zealand and is now based in America but, with a Scottish father and Welsh mother, he was one of seven playing under the British flag on Monday.
But while his talent was obvious in the tournament's opening match on Court Two, Norrie proved too inconsistent to trouble Tsonga, the world number 10 and a two-time Wimbledon semi-finalist.
In fact Norrie went toe-to-toe with the Frenchman early on but his concentration wavered at 3-3 in the first set, when a double fault and missed backhand volley cost him the break.
It seemed to knock the youngster's confidence because he was broken again at 5-3 as another forehand blazed wide and put Tsonga one set ahead.
The second and third sets were even more straightforward for Tsonga, who managed two more breaks in each without facing a single break point on his own serve.
Norrie once even held his hands out in resignation as another Tsonga ace flew by and his defeat was confirmed after an hour and 23 minutes when a final backhand hit the net.
Australian 20th seed Nick Kyrgios retired injured in his first round Wimbledon match on Monday after losing the first two sets to French doubles specialist Pierre-Hugues Herbert.
Kyrgios, clearly still struggling from the left hip injury that forced him to drop out in his first round match at the Queen's Club tournament in London this month, was 6-3 6-4 down to the world number 70 when he asked for a physio to come on court.
Apart from in very rare flashes, the 22-year-old rarely ran to pick up the peppering of drop shots and lobs coming from Herbert, and sat with his head in his hands at the changeover after having his serve broken for 4-3 in the second set.
Kyrgios, who has never lost in the first round at Wimbledon, reached the last 16 last year before being beaten by eventual champion Andy Murray.
Japan's Kei Nishikori breezed through his Wimbledon first-round clash with Italy's Marco Cecchinato 6-2 6-2 6-0 on Monday, demolishing an opponent who was playing his first senior-level match on grass.
The ninth seed did not disappoint the legion of Japanese fans who gave him a hero's welcome as he walked on to Court Twelve, outclassing his rival from the first point when he powered a backhand winner down the line.
Stan Wawrinka's hopes were shredded in a blitz of heavy artillery fire as Russian Daniil Medvedev, making his Wimbledon debut, ousted the fifth seed in the first round with a stunning display of power hitting.
Three times grand slam champion Wawrinka was thoroughly out-gunned by 21-year-old Medvedev, who had the Centre Court crowd on their feet as he pulled off a dazzling array of winners to wrap up a 6-4 3-6 6-4 6-1 victory.
