Will David Duval win the U.S. Open?

This year on the LPGA tour, we've seen improbable comebacks by Karrie Webb and now Se Ri Pak. Se Ri's victory yesterday at the McDonald's was even more improbable than Karrie's victory earlier this year, at least in terms of how far Se Ri's game had fallen off ... basically, the face of the earth. (Karrie's was more improbable with the holed out wedge on 18, although Se Ri almost holed her 4 iron.)

Meanwhile, Michelle Wie continued to contend, only to shoot herself in the foot with shaky putting down the stretch. What's new?

I'm assuming David Duval is playing in the U.S. Open from an earlier exemption, but I could be wrong. If he is, then a victory for him this week would be the most improbable comeback at a major ever known to man.
