You've gotta be kidding me, still with the hamstring?! Seriously, how much time off does he need to have that heal up? A part of me thinks that he might just be using it as a weak excuse in order to blow off the entire clay court season. A big mistake in my opinion, as he has ZERO points to defend so he should be out here trying to snag as many wins as possible. If he skips out on all the clay events and then slips up at Queens Club (where he has SF points to defend), there's a good chance he won't be seeded at Wimbledon.
