The stakes at the BNP Paribas Masters just got higher as the quality of the tennis improved to another level with the big guns having to carve out their victories in long matches to move into the quarterfinals. World No.2 Roger Federer narrowly avoided defeat as he edged out compatriot Stanislas Wawrinka 6-3, 6-7(4), 7-5. Joining him in the last eight is 3rd seed Andy Murray who won against a feisty Carlos Berlocq in straight sets 7-6, 6-4. Eight seed Jo Wilfried Tsonga also came through in a similarly hard fought encounter and came back from a set down to see off Canadian Milos Raonic 4-6, 7-5, 6-4. Kevin Anderson and Tomas Berdych also won their respective fourth round encounters to set up a great quarterfinal match-up.
Roger Federer dominated his compatriot for the better part of the first two sets and was serving for the match at 6-3, 5-4 up but the 18th seed broke Federer’s serve to love and forced the match to a tiebreak which he won 7-4. The momentum swung Wawrinka’s way and he used it to go 3-1 up in the third set putting all the pressure on the 2nd seed. Federer though was up to the challenge and he broke back to level proceedings, eventually winning the last set 7-5.
