110 mph first serve and no second serve... Who are you? Fernando Verdasco?
For dragging him to net, have you considered pulling him off the court, then hitting a low, short slice to the other side? Not a dropshot, but a knifing slice that just lands short. He comes up, you pass him.
Have you considered hitting it wide and deep enough into his backhand corner so that he can't hit a forehand? It's not always enough to just hit to that side, but you also need to hit it far enough that he can't just run around it. If he tries to run around the ball and hits it from outside the sidelines, punish him by going into his forehand corner. He gives up SO MUCH court if he tries to run around a deep, wide backhand.
