Novak Djokovic negotiated big-hitter Hubert Hurkacz to reach the fourth round at Wimbledon.
The defending champion dropped a set for the first time at the Championships to the 6ft 5in Pole, losing a tie-break in the second.
It proved only a minor inconvenience, though, as the four-time winner surged through 7-5 6-7 (5) 6-1 6-4. The only problem Djokovic faced in the first set was being told he could not wear his cap by the umpire because it contravened Wimbledon's all-white rule.
It would be hard to find a whiter cap, frankly, and Djokovic had worn it during his second-round match, but apparently the black inner lining violated the strict dress code.
Djokovic duly played on cap-less and Court One was a server's paradise until the Serb made the breakthrough in the 11th game, Hurkacz saving three break points but succumbing to a fourth.
Hurkacz was not going to go away quietly, though, and he fashioned two break points at 6-5 in the second, one with a Boris Becker-esque dive volley at the net.
The hunt for a fifth title continues…

Djokovic repelled both to force the tie-break, but another spectacular volley from Hurkacz helped him level the match.
Stung into action, 15-time grand-slam winner Djokovic broke to love twice as he raced away with the third.
A single break in the fourth was enough to wrap up proceedings, the 32-year-old coming through a decent test to safely make week two.
Argentine Guido Pella pulled off a major upset at Wimbledon on Friday, beating fourth seed and 2018 finalist Kevin Anderson in straight sets to reach the last-16 of a Grand Slam for the first time.
The 29-year-old, who beat the big-serving South African 6-4 6-3 7-6(4), will play Canada's Milos Raonic next for a place in the quarter-finals.
"I don't know how to describe this moment," an emotional Pella said. "This match was unbelievable for me. I was focused the entire match and it was amazing.
"My mind is in the right place. I'm playing much more aggressively than previous years. I'm confident. I just need to continue to fight for every point.
"To be in the second week is an unbelievable feeling."

Anderson, runner-up to Novak Djokovic last year, arrived at the All England Club after an injury-hit season due to a troublesome right elbow and his serve-and-volley game was derailed by a lack of sharpness at key moments.
Pella, the 26th seed, made a nervy start, saving two break points in his opening service game on Centre Court before settling into his stride.
He kept the 6ft 8in (2.03 metres) Anderson, the tallest man to play a Wimbledon final, guessing with a dizzying array of shots, including his backhand slice, and made 13 unforced errors compared to 29 from his opponent.
There was little to choose between the two in the opening set until Anderson's first serve deserted him with the score level at 5-5.
Anderson had reached the third round without his serve being broken, but Pella turned the screws at the right moment, converting his fourth set point to claim the opener when the South African netted a forehand.
That rattled Anderson, who came out swinging at the start of the second set, but the 33-year-old's timing was off and Pella broke again to race into a 3-0 lead.
Anderson clawed a break back when Pella sent a backhand volley wide with the court at his mercy, but the Argentine broke again and served out the set to take a 2-0 lead.
Anderson, who hit 14 aces and 40 winners, fought on grimly to send the third set into a tiebreak, but Pella kept his composure, winning a stunning exchange of volleys that brought the crowd to its feet to earn two match points before claiming the biggest win of his career.
