Nadal's gamesmanship is very minor when compared to other champions like Mcenroe, Murray and Djoker & etc. As far as Henin retirement is not gamesmanship --it doesn't help you win. Hand raise, yes, but don't go down the WTA path. It's even more extreme than the men. Nadal has done very little and I don't want to hear about asking to stop play in a down pour at the FO.
