the stats are very odd, cause he serve very well as it seems and yet he lost a huge percents of the points on his first serve on this very fast indoor surface.
that is very suspicious
If he had served like he can with all that power there is no way he lose so much points on the serve. also Grigor didn't make DFs to suspect he decrease the spead or something? I hope it is not an injury, cause honestly these stats are unexplainable for me.
