By Michael Roddy LONDON (Reuters) – Andy Murrays defeat at Wimbledon on Wednesday should have come as no surprise, according to a new IBM system that claims the Briton was a less aggressive player than opponent Grigor Dimitrov. Computer giant IBM credited Dimitrov with 50 aggressive forehands to 44 for Murray during Wednesdays mens quarter-final match, in which Bulgarian Dimitrov knocked out last years mens champion in straight sets. While the two players almost tied on aggressive backhands, at 18 for Murray and 17 for Dimitrov, the Bulgarian scored a net 86 aggressive shots in total during the match, beating Murrays 71, IBM said in statistics provided to Reuters on Thursday. This years Wimbledon marks the first time IBM has used the system.
