OAKMONT, Pa. — Drivers have been tested this week at the U.S. Open, just as they were last month at the PGA Championship and, presumably, in April at the Masters.
But Mike Whan, the CEO of the USGA, which runs the U.S. Open and administers testing across the game and at PGA Tour events, said he is not in favor of disclosing the results and that what occurred at the PGA with Rory McIlroy strengthens that belief.
