Andy Murray had to hold back the emotion as he celebrated a winning return to the ATP Tour at Queen's.
Murray had hip surgery in 2019 and had not won a grass-court game since 2018, with last year's season having been cancelled due to the coronavirus pandemic.
Having struggled with a groin injury, the 34-year-old Scot last played in March, yet showed flashes of his old self in his 6-3 6-2 victory over Benoit Paire, having taking up a wildcard into the pre-Wimbledon tournament.
It was an emotional moment for Murray, who said: "Look, I love playing tennis."
The five-time champion was fighting back the tears as he continued: "Obviously, competing is why you put in all the hard work.
"The last few years, I've not got to do that as much as I would have liked so, yeah it's just great that I'm out here and able to compete again.
"The body is old, but I did quite well today in terms of my movement.
"It's my first match on grass in three years and I've only played three or four practice sets in the build-up to this, so I didn't know exactly how I was going to play or feel – but I think for a first match it was good."

Murray will face top seed and world number nine Matteo Berrettini, who defeated Stefano Travaglia 7-6 (7-5) 7-6 (7-4).
British number one Dan Evans beat Alexei Popyrin, while fourth seed Alex de Minaur also progressed to round two, having come from behind against Laslo Djere. Second seed Denis Shapovalov overcame Aleksandar Vukic.
Tuesday's results mean, for the first time since 2005, four British players have won at Queen's, with Cameron Norrie and Jack Draper having gone through on Monday.
Meanwhile, after losing to Stefanos Tsitsipas in the French Open quarter-finals, world number two Daniil Medvedev crashed out of the Halle Open in the first round.
Jan-Lennard Struff was his conqueror, claiming a 7-6 (8-6) 6-3 triumph, which the German labelled as "the biggest win of my career."
There was better luck for third seed Alexander Zverev, though he did need three sets to see off Dominik Koepfer 6-4 3-6 6-3, just four days after facing Tsitsipas in the Roland Garros semi-finals.
Ugo Humbert awaits Zverev, while Felix Auger-Aliassime beat Hubert Hurkacz to tee up a tie with Roger Federer. World number seven Andrey Rublev got the better of Karen Khachanov.
