The Memorial Tournament tees off this morning at the Muirfield Village Golf Club in Dublin, Ohio.  The field is loaded honoring the most prolific winner in PGA Tour history.  Jack Nicklaus is the tournament host, course designer and the number-one reason the stars of golf show up for this, what is likely to be, a final tune-up for the U.S. Open in two weeks.  Since most of the game's best skip the FedEx St. Jude Classic next week, this will be the last time we see the likes of new number-one Luke Donald, Rory McIlroy [[ MAC-il-roy ]], Tiger Woods, Phil Mickelson and Hunter Mahan [[ MAY-han ]] until Thursday, June 14th at Olympic Club.  Steve Stricker is the Memorial defending champion after claiming a one-stroke win over Matt Kuchar last year.
