Venus, but not Serena, is hitting a lot of swinging volleys again in the last few matches I've seen on TeeVee. I consider the swinging volley to be a signature stroke of many counterpunchers. People are always asking how to play a pusher? Well, if pushers hit low speed groundstrokes, why don't people step inside the baseline more? This way, you are close enough to aggressively run up and whale away at floaters. This doesn't work so well against pushers who hit low slices, but it is killer against topspinning pushers. Turn those lazy, high % groundstrokes into dead ducks!
