Fish looks as good and strong as ever. All this talk about heart problems could be a tactical ploy. One, it could soften opponents and make them play with sympathy vs. Mardy, do I really want to beat Mardy, the poor guy could have a heart attack. Two, Mardy has created a built in excuse if he has a poor summer and can't defend all his points, thus dropping out of the top 10 or 20. It wasn't that Mardy choked on the pressure, but he's weakened by a bum ticker. This might keep his sponsors supportive despite a ranking drop. Just so suspicious about all these injuries and ailments in tennis. Even Venus' seems a bit curious. So was Fed's and Roddick's "mono." And Murray's back, etc. A smart tactic in boxing is playing possum and bluffing the opponent. This tactic is also used in tennis, with the use of faking injuries and ailments, look how Rafa, Djokovic and Murray have utilized this tactic. Fish might be taking us all for a ride with this elaborate ruse about his heart problems. He is looking very strong and playing high quality tennis. Of course, I pray for Mardy and hope he's super fit and healthy and will not suffer any kind of incidents on court during a grueling tough match.
