I'm slow writing about this, the Hernandez v Koellerer match earlier in the week created quite a fuss in the media after some seriously dodgy betting patterns occured pre-match. Some of the coverage was laughable (William Hill suggesting suspicions were aroused after a £4000 bet), but most of it was alarming for those of us honest in-running bettors. This sort of thing only gives those who seek to limit in running betting more ammo. Let's hope the integrity teams at the various bookies were able to trace those that placed the bets, though these things are incredibly difficult to prove.
