Juan Martin del Potro had his first on court training session on Friday since undergoing surgery on his left wrist in March.
The Argentine has been forced to miss the French Open after his injury, and he announced that he was back in training via a message for his fans on his Facebook page.
He wrote: "Hey everybody! I've got good news to share: I'm back on a tennis court! It was a light hit, some forehands and volleys without major movement, since I still wear the splint on my left wrist. At this point I have to be cautious, without skipping any step during the recovery time. As always, thanks for your messages!!"
The on-court session was held in Argentina, where he went through some hitting practice as he continues to make small steps in his period of recovery, as the session lasted just 20 minutes with his coach Franco Davin.
The world number seven has not competed on the ATP tour since retiring in his match against Indian Somdev Devvarman in Dubai in late February.
It is not the first time that the 25-year-old has suffered from wrist injury problems, as he was forced to miss almost the entire 2010 season, after he had reached his career high ranking of fourth.
It remains unclear as to when he is expected to be back in action, but the 2009 US Open champion has been undergoing an intense period of rehabilitation, and there is a chance that he could compete at Wimbledon, which starts at the end of June.
The surgery was carried out by Doctor Richard Berger, the same man who operated on Del Potro’s wrist four years ago, and the procedure was carried out at the Mayo Clinic in Rochester, USA.
He has been using a special splint to support the wrist while the ligaments heal, and the surgery was seen as a success.
The wrist problems curtailed what had been a positive start to the year for Del Potro, as he had made it back to a world ranking of fourth after winning four singles titles in 2013, though he has never reached the final of another Grand Slam since first encountering the injury in 2010.
There has only been one occasion where he has threatened to win a second major since then, when he reached the semi-finals at Wimbledon in 2013, and he was beaten in five sets by Novak Djokovic.
Despite his rise in the world rankings, he suffered an unlikely loss in the second round of the Australian Open in January, when he was beaten in five sets by Spaniard Roberto Bautista Agut.
That loss came after his 18th singles title victory, which came at the Apia International Sydney in January, in his first tournament of the year.
