Rezai and  Gulbis make this late trading session very interesting. Both players won 1st set and Gulbis just lost 2nd set to Federer 6-1. Nice swings in both matches as shown on screen shots. My screen is looking nice at the moment and I am having a break from trading until next match, Ferrer-Murray later on which will be the last one for today. Should be great match for your eyes and good for traders.
Good luck if you get involved in trading any of these matches !
