They need to ban poly strings IMMEDIATELY. If they don't, they need to make the tennis court 1/2 the size because being able to hit the ball as hard as you can and still have the ball land inside the court was never imagined when the sport was invented and they standardized the current size of the court. If tennis was invented today with today's racquets and strings, the court would be half the size. There is supposed to be a penalty for trying to hit the ball hard in that the ball might go out, but that's no longer even part of the equation anymore which is an abomination. That's why the artists can no longer compete as only the physical brutes like Nadal and Serena win everything.
