Almost every single pro tennis player brings the racquethead above his head on the backswing. As gravity drops the racquethead from that point, the wrist is free to pivot. How fast the racquethead travels as the racquet travels through a high-to-low-to-high pendulum sweep is largely dependent on the relative weight distributions of the arm and racquet.
The pendulum action is easy to see if you watch these guys in slo-mo, who have pretty good forehands:
POG OS. 368 SW, 12.54" balance, 21.0 MgR/I.
Problend kevlar 16 / Prestretched SPPP 17, 72/50 lbs.
