AN AMERICAN will play in the ATP Mexico Open Final following the quarter finals results, while in the WTA Tournament, a couple of teenage qualifiers continued their runs to move into the semi-finals.

Seventh seed Bulgarian, Grigor Dimitrov took out third seed, Stan Wawrinka in straight sets to set up a semi-final clash with tournament favourite, Rafael Nadal. Dimitrov downed the Swiss star 6-4 6-4 in an hour and 24 minutes, winning 72 per cent of his first serve points from 70 per cent efficiency, while saving three of a possible four break points. The seventh seed also broke three times and dominated Wawrinka’s second serve, winning 67 per cent of the Swiss talent’s serve. Now he has to step up further to take on the Spanish start, with Nadal holding a remarkable 12-1 head-to-head record against the Bulgarian.

Nadal knocked off South Korean, Soonwoo Kwon 6-2 6-1 in an hour and a half, downing the world number 76 without too much trouble.
