Jack Nicklaus has had a pretty good career playing on grass, so it’s only fitting that his favorite tennis tournament is Wimbledon, where he’s been spotted the last couple of days spectating at Centre Court. He’s visited the last couple of years, in fact, having first started coming in the early ‘70s prior to the Open Championship. Nicklaus is something of a grass-court aficionado with three lighted ones at his home in North Palm Beach (he used to have a clay court, as well, until Jack II built a home over it). A decent doubles player who likes to serve and volley, Nicklaus usually plays every weekend with a dozen people or more, including former pros like Cliff Drysdale and Butch Buchholz. Last December, Nicklaus got a surprise visit from the world’s No. 1 doubles team, Mike and Bob Bryan, and Jack and Bob preceded to steamroll the competition in the “Golden Bear Day Camp” tournament (photo above). Nicklaus’ stop in London is beginning of a 13-day, 7-country European trip—part business, part pleasure—that will also take him to Croatia, the Czech Republic, Hungary, Italy, Morocco, and Russia.
