Juan Martin del Potro will not return from wrist surgery during the Asian swing as originally scheduled, with the Argentine pulling out of three tournaments, including the Shanghai Masters.
Del Potro reported that while he is training again, he is not yet ready to compete in matches. "I would like to take this opportunity to tell you, my fans, that although the recovery of the wrist is progressing very well, I need a little more time to reach the competitive level necessary to compete week after week," he said on Facebook.
The former No. 4 has not played singles since Dubai in February, withdrawing from Indian Wells and undergoing wrist surgery just before Miami.
Del Potro indicated he still might return this season, however, by playing one of the indoor events such as the Paris Masters. "I will keep working hard on my recovery to play the European season," he said.
