Reminding me of Greg Norman’s exit-causing injury at the 1988 U.S. Open at The Country Club in Brookline, Mass., Rory McIlroy twanged his wrist in similar fashion at the PGA Championship this afternoon. In the broadcast booth, there was concern all around as the young champion tried to shake off the pain and continue. Right now a “physio” guy is giving the lad a thorough examination.
