Which of the following tournaments is NOT owned by the PGA of America?

The Masters is indeed the tournament that is not owned by the PGA of America. Instead, it is organized by the Augusta National Golf Club, making it an independent event. The Masters is one of the four major championships in professional golf, but it operates separately from the PGA of America and is renowned for its unique traditions, such as the green jacket awarded to the winner.

In contrast, the PGA Championship and the Senior PGA Championship are both owned and conducted by the PGA of America. The Ryder Cup, while it involves collaboration between the PGA of America and the PGA of Europe, is primarily governed by the PGA of America on the U.S. side. This distinction highlights the independent nature of The Masters compared to the other tournaments listed.
