Stan Wawrinka did not let up in his straight set upset over country Roger Federer to reach his first French Open Semi final.

Wawrinka came into the match with a 2-16 head to head against Federer with both previous wins coming on clay, but never beating him in grand slam competition (Federer leads 4-0).  Wawrinka would put all of that behind him when he opened up the match breaking Federer in third game. Federer wouldn’t roll over, holding firm on his serve for the rest of the set, but Wawrinka staved off all four break points he faced.

The Lausanne Native kept Federer on the defensive most of the match, leaving little room for him to get aggressive or hit winners off the forehand wing (0 forehand winners from Federer in the first set).

The set was opened by a Federer serve, and Roger would maintain pressure over his compatriot looking for a hole to exploit, but to no avail. Wawrinka would break in the 7th game, and again in the 9th game to take a commanding 2 sets to love lead.

Federer would serve to open the set and would maintain pressure over his compatriot looking for a hole to exploit but to no avail. The Swiss would try to force momentum on his side by exploiting the net, but Stan was too good from the back for Federer to make much good out of it. Wawrinka would break in the 7th game, and again in the 9th game to take a commanding 2 sets to love lead.

When down two sets to love, Roger Federer has only completed the comeback 9 times, but Wawrinka wasn’t going to let today be his 10th. Wawrinka continued to bully Federer around the court, but it wasn’t the power so much that was making it difficult as it was the depth of shot. Wawrinka kept the ball well past the service box forcing errors off both wings, while dictating play throughout with little trouble on serve. With 0 break points for either player it would be decided in a tiebreak. Both players continued to hold firm on their serve until a controversial call at 3-3 in the breaker that ultimately gave Wawrinka the break, and ultimately the match as he took it 7-4.

The 30 year old Wawrinka will contest his second consecutive major semi of the season after falling in 5 to Novak Djokovic in Melbourne. He will take on home favorite Jo-Wilfried Tsonga for the seventh time in a rematch of the Davis Cup Final.
