For a player at this level, the opportunity is there. If you happened to draw a highly seeded player in the first round that you expected to lose to, you would expect to take home a check for $117.50 or just over £71. Alternatively, you could arrange for someone to place bets to win £500 [$816.30] at each of the eight bookmakers that are covering the match to give you a £4,000 [$6530.40] profit for the match. Given that you were expected to lose the match, it would not appear suspicious. Handled effectively, the bets would likely be small enough that they would not be flagged up by any one of the bookmakers.
