What, they aren't really baseliners, they both look to get to the net, but do do a bit of baselining if they have to.
Frank's has a very good serve, a pretty good forehand and tries to get into the net at every chance he gets, regardless of if it will be an easy volley or not, he is probably a top 5 or top 10 volleyer in the top 115 or whatever, his hands are amazing. He is terribly inconsistent from then back of the court often times, but he does have two weapons, his serve and his net play. He hits the ball very flat, like your typical Canadian tennis player.
Peter's serve is average, and his second serve is probably below average, but his ground game is alright, much more consistent than Frank's. Good forehand and backhand, with lots of spin. He, unlike Frank, does not have any weapons. His forehand and backhand will move players around but they will not produce flat out winners and he often plays with a lot of margin for error, not really going for winners but making his opponents hit a lot of balls. He is okay at the net, but generally only goes to the net when he is expecting to have an easier volley because he doesn't have the weapons to finish the point from the baseline.
This is just how I see the two players, and maybe I am wrong, but I really feel that Polansky plays like a European, like Igor Andreev for example and Dancevic plays a lot like an American, like James Blake for example.
