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:
BLX Blade 98. 26.75". 13.195 oz., 12.55", 357 SW. 16x20 (outer mains skipped)
Pre-Stretched Ashaway Kevlar 16g/ZX Monogut Natural 16g, 90/40 lbs
