don't know why he's barely slicing at the moment. it can be very effective and the point you mentioned shows it.
happy for the dog, brilliant final tomorrow!
the problem is when Dolgo is using his slice a lot he tends to get STUCK on it and never pull the trigger for a strong groundstroke.........
He is much more effective when keeping the variety up and sticking with a strong baseline groundstroke game and drop shots occasionally!
plus one reason the slices worked so well in the point you two mentioned is because Sam was a bit offput by it because Alex had not been slicing much during the match.
he's smart to save the frequent slice as a thing to mix up opponents midway through the match, his groundstrokes are just so sick at times that Dolgopolov is smart to stick to aggressive. remember he has played mediocre the last year and in it he has sliced FAR TOO MUCH. this aggressive game works for himmm
