Peter Jacobsen has withdrawn from the U.S. Senior Open in Omaha, Neb., because of heat-related illness.

In this week's 'What We Learned,' we learned that Royal Lytham & St. Annes will have a slightly different look than we're used to, that Roger Chapman is a bigger stud than he gets credit for being, and at least one member of our staff is jonesing for the British Open.

Roger Chapman earned the right to be mentioned in the same sentence with Jack Nicklaus, Gary Player and Hale Irwin. Not bad for a self-described former European Tour journeyman.
