Del Potro eyeing March return

The Argentine underwent surgery on his left wrist in January, the second time he has had to go under the knife, after withdrawing from the Australian Open the day before play got underway at Melbourne Park.

Del Potro headed home to begin his recovery and has now stepped up his plans for a comeback. The 26-year-old has penciled in March 25 in Miami as the possible date of his return.

"I'm in full recovery, I'm going faster than the time frame the doctor set for me as a goal and that has me enthused and that's why I believe my return will be very soon," he commented at a sponsor's event in Buenos Aires.

Del Potro admitted that at times his injury has taken a huge mental toll, but that the support he has received from his fans has given him the strength to carry on.

"It's very hard to live with injuries, I would have trouble getting up some days. For a year now the first thing I've been doing after waking up is move my fingers," he explained.

"The reception I got in Sydney made me feel fans had not forgotten me," he added.

"It charged me with the energy to take the decision to go and see the doctor again losing no more time because I felt that if I recovered my physical condition I would rediscover my game and I don't care how long it takes."
