And while Inbee Park is no sure thing to win, she has to be the overwhelming favorite. Park leads the LPGA with five victories so far in 2013. That includes wins in each of the two preceding majors - the Kraft Nabisco Championship and the Wegmans LPGA Championship - and Park is coming off victory at last week's Walmart NW Arkansas Championship.
The defending champ is Na Yeon Choi.
The 2013 U.S. Women's Open also serves as the unveiling of Sebonack Golf Club to the golfing public at large. Sebonack is less than 10 years old, another millionaires' club on Long Island, its design the result of a collaboration between two very different architects, Jack Nicklaus and Tom Doak. The Women's Open is the first significant golf tournament played there, the first time the general public will get a look at the course.
There's another major this week, too: the Senior Players Championship. Colin Montgomerie makes his Champions Tour debut this week. And Monty said a few days ago that he plans to play quite a bit on the U.S. senior circuit.
The European Tour plays the Irish Open, and the Big Irish 3 - Rory McIlroy, Graeme McDowell, Padraig Harrington - top the field.
And the PGA Tour plays the AT&T National, the tournament that benefits Tiger Woods' foundation. Alas, Woods - the defending champ - isn't playing. He's resting a strained left elbow until the British Open. But those who are playing include Jason Day, Hunter Mahan, Adam Scott, Brandt Snedeker, Rickie Fowler, Jim Furyk and Nick Watney.
