Andy Murray
Murray fails to return to the world's top four.

Andy Murray failed to reach his first final of 2014 after being defeat by Bulgarian No.1 Grigor Dimitrov for the first time at the Acapulco Open in Mexico.

Murray, playing his first semi-final since claiming the Wimbledon title last July, won the first set but allowed Dimitrov to level the match in the second set tie-break.

Dimitrov appeared on the brink of the final after breaking the world No.7 early in the deciding third, but despite Murray rallying to level, the 22 year old won the resulting tie-breaker to prevail 4-6 7-6 (7-5) 7-6 (7-3) and set up a meeting with South African Kevin Anderson on Sunday.

Failure to win the tournament, Murray's first since leading Great Britain to Davis Cup success over United States, denies the Scot the opportunity to return to the world's top four ahead of the start of the American hard court season in Indian Wells and Miami.
