Tommy Haas is playing now ?
It's Robin Haase
, a young Dutch player.
Coming back from a severe knee injury which had him sidelined for about 18 months, trying to get back to his ranking (mostly playing challengers) which he had two years ago - around #50.
Rafa will take this in straights, but mark my words: Haase will do better than Nishikori. He's a genuine fighter and serving well recently.
Oh, and btw, can people please STOP calling these players Hass/Hasse? That means 'hate' in German. Not nice.
