To make it easier to understand my unit rate (and P/L) I make 1 unit as 100€.
So my current P/L:
Wawrinka over Haase and Nadal over Davydenko
Multiple 3u @ 1.7
Wawrinka had to fight hard in his 2nd round match against an inform opponent (Goffin) who hit the ball really well this tournament. The Swiss has shown some fighting spirit and just looked more experienced. Although the scoreline was very close I rate the win high and Haase on other hand came through two times in 3rd sets. He looked exhausted in the end in both matches so I can imagine these matches took some gas out of his tank.
I know Rafa had doctor on court and does not feel 100% (due to flu) but he played doubles later on too so I think it will not be that serious. Gulbis was a very tough opponent and Davy will not play better than the young Latvian (from baseline yes but not serving wise). And without these free service points Rafa is almost not beatable nowadays outdoors.
Wawrinka over Haase and Tipsarevic over Nishikori:
Multiple 1.5u @ 1.8
Nishikori had treatment against Cilic on his leg but still managed to win against the Croat and Falla although 4:6 0:3 down (2 breaks in 2nd). The Serbian looks fit and had two easy wins and comes in fresh. The service should be a huge advantage for Tipsarevic in this one and give him the edge over the injury prone Japanese.
