Can You Help ID These Golfers?

Can you help identify the golfer autographs on this hat.? From left to right, I see Phil Mickelson, then Davis Love III, then 2 or 3 signatures I can't figure out, and finally, on the far right Miguel Jimenez. My father-in-law was a marshal at Torrey Pines, so, my best guess is that these might be from the 2001 Farmers Insurance Open in 2001. At least, that appears to be the only time Phil, Davis, and Miguel were at that tournament at the same time. Any help or ideas you can give is greatly appreciated.
