Reed: Del Potro will need time
When a player struggles with a major injury, you never know how they are going to react.
Some people are never the same player again. I'm not sure Marat Safin ever fully recovered from his wrist injury, although obviously there were other issues as well. Discipline was very important with him but it seemed to me like the wrist was a major issue.
I think it'll take a bit of time for Juan Martin Del Potro to get himself back on track. The injury happened at just the wrong time. If you think what's happened since then, it couldn't have happened at a worse time for the Argentine.
It was great that he won the US Open but I think he might have won at least another Slam by now - Murray for one reason or another hasn't won one, Djokovic is starting to play well, Federer hasn't played that well but is starting to look better again and so it's been left to Rafael Nadal to clean up.
If Del Potro had been there he might have found it harder and I think he'd have won one of the summer Slams and possibly the Australian Open.
Only he knows the feel of the thing and how severe it is. Is he having to be more careful with the injury? Is he able to hit full-out on his ground-strokes? I sense, without having seen too much, that he wouldn't have come back yet unless he could hit full-out.
So it's just a question of getting his game back on track. It's bound to take time to get into his groove, especially with the kind of power game he has.
Kim Clijsters really struggled with a wrist injury before she retired but since she's come back there's been no sign of that problem. And it may be like that for Del Potro as well. I hope so because I think there's another two or three Grand Slams in him.
I shouldn't expect too much for him for the rest of the year but at this stage I'd look at him to be a threat for the Aussie Open next year.
