Re: Heather Watson
It's interesting that both Laura and Heather seem to have opposing strengths and weaknesses. Heather tends to be better at keeping the ball in for longer... she just doesn't do anything with it. The ball is in play, but it's not likely to be a winner or force an error. Which means that if she's playing someone who can do something with the ball she's handing her opponent plenty of chances to do so. Laura on the other hand hits the ball hard in places where it's going to be tough or impossible for the opponent to return. However, she's also highly inconsistent for a top level player meaning she'll give her opponent UEs hand over fist if they give her the chance.
Heather's also a good mover, Laura isn't. If we could combine the two we might have a world beater. Shame the fusion dance doesn't work in the real world.
