Phil Mickelson plans a brief return to the PGA Tour in time for the U.S. Open.

He has not played since announcing that his wife, Amy, has been diagnosed with breast cancer. Tests have given them hope the cancer has been caught early, with more testing to be done over the next month.

Mickelson intends to play the St. Jude Championship next week in Memphis, then compete the following week in the U.S. Open at Bethpage Black.

Jack Nicklaus and Tiger Woods will play together in the Memorial Skins Game tomorrow in Muirfield Village in Dublin, Ohio, only the second time and first since 2000 they have competed against each other in the same group.

Nicklaus and Woods will be joined by Stewart Cink and Kenny Perry.

The other group will have Vijay Singh, Padraig Harrington, Jim Furyk, and Camilo Villegas.

President Obama will be the honorary chairman of the Presidents Cup, to be played held Oct. 8-11 at San Francisco's Harding Park.

Horse racing

Calvin Borel, back on Kentucky Derby winner Mine That Bird, is anticipating another Triple Crown victory in Saturday's Belmont Stakes.

The gelding did a half-mile in 50 seconds at yesterday's workout at Churchill Downs in Kentucky.

Borel would have ridden Kentucky Oaks and Preakness Stakes winner Rachel Alexandra if the filly had entered the Belmont Stakes.

He now has a chance to win all three legs of the Triple Crown on two horses, something no jockey has done.

Vincent O'Brien, an Irishman and one of horse racing's great European trainers during a career that lasted more than a half century, died yesterday at age 92 at his home in Straffan in County Kildare.
