I'm very relieved but not surprised at this decision. Andy should never have played in the first place and it's a shame that the ATP put pressure on players to particpate in Toronto right after the Olympics. I suppose Andy was lucky that he had a fairly easy first match even if he did pick up what is hopefully a minor problem due to suddenly playing on a different, and harder, surface, but it may also have done him a big favour. No way did I want to see him beaten by Raonic again. Also I don't think he'll be the only top player who'll have a few niggles. Early exits, tanking and withdrawals are only to be expected with the USO so close.
The press really should get a grip on themselves and stop their doom, gloom and despondency speculations. They haven't a clue what the true situation is here. Andy has a first-class physio and a great team who will make sure he's as fit as possible for the USO. Also this shouldn't be seen by him as a setback - his body is screaming out for rest and I really hope he takes more than just a couple of days off.
Oh and the strapline at bottom of press conference clip from ATP was Andy Murray Olympic Champion - makes me feel so proud each time I see or hear that
I get a real buzz every time I see or hear that too.
