This is the qurterfinal in Cincinnati in USA. Mardy Fish will try to progress to semifinal and I believe he is able to do that. Mardy Fish is in good form. In Cincinnati he won against Simon, Verdasco and Gasquet. He did't loose a single set so far, all three matches ended with 2:0 for Fish. He is serving very good, made a little double errors and unforced errors. I am sure he will push Murray very hard. The fans are giving the great support to Fish, I am sure today will be the same. And Murrey lost from Fish in the past. It is very important that Fish won the last game against Murray on July, the 10-th this year. Fish managed to beat Murray with 2:1 in sets and it surely boost his morale. I believe in another victory for him.Murray played two heavy tournaments in Los Angeles and Toronto this month. It is normal he is tired at the moment, specially if we know he reached the both finals. So, in form Fish have an advantage against tired Murray. So, I think Fish will qualify to the semifinal.
