I did not see the match. However, I doubt that Fed would have thrown the match consciously. If at all he threw it would have been subconscious only as others have alluded.
I was expecting Fed to lose early either here or in Halle (not necessarily this specific loss). Moreover, losing once before Wimby sort of releases pressure somewhat instead of going to Wimbledon as a winner of four tourneys in a row. I hope he wins Halle though.
p.s. Front, do you remember once in Brisbane Fed was playing lousy and Tommy beat him. We were the only ones commenting on it on the board. But, for some reason that match is not showing up in the H2H between them in ATP. I think it was SF at Brisbane, in Roger's first try at Brisbane, may be 2014.
