The Swiss improved his head to head against Fish to 8-1, having also beaten the American in their 2010 Cincinnati final encounter in three hard fought sets 6-7 7-6 6-4.
This time around, Federer struck very early in the match, breaking his opponent’s serve in the opening game of the first set and then breaking Fish for the second time when he was serving to stay in it.
Both players showed a lot more consistency on their serves in set two and after no breaks on either side, the Cincy crowd was going to witness a tiebreak. It was the Swiss who kept his composure and didn’t allow Fish to get back into the match as he took the ‘breaker’ 7-4.
Next up for Federer will be his coutryman Stanislas Wawrinka, who defeated Canadian Milos Raonic in a tough battle, winning 2-6 7-6 (5) 6-4 after almost 2 and a half hours.
Raonic never let Wawrinka find his rhythm as he cruised through the first set, taking it in just 33 minutes.
Although the Swiss found was trailing Raonic in set two as well, he managed to fight back to take the set into a tiebreak and force a decider.
This seemed to have broken the Canadian’s resistance, who dropped his serve in the third game of the deciding set, which proved to be just enough for Wawrinka to book his place in Saturday’s semifinals against Federer.
