Tipsarevic refused to shake the umpire's hand at the end of the match.
He had a few outbursts at the umpire due to bad calls and there was a long argument at the start of the third set which involved both players. I think one of the linesmen started to make a call but wasn't decisive. Either way, it was bad form from Tipsy because the umpire pretty much over-ruled the decisions which initially went against him!
Granollers' game isn't particuarly powerful but he painted the lines really well, made some nice touch volleys and played some good drop-shots, which was wise as Tipsy was struggling with the court and fell over a few times. His backhand is such a weird shot because he has such late preparation on that stroke!
