BETHESDA, Md. -- Four players competing in the 111th U.S. Open are celebrating birthdays this week.

Fred Funk turned 55 on Tuesday and is the oldest player in the field while Hiroyuki Fujita and Phil Mickelson turn 42 and 41, respectively, on Thursday. Anthony Kim is the final birthday boy – celebrating his 26th on Sunday, which also happens to be Father's Day.

A win on Sunday at Congressional would make this a memorable week for anyone, of course, but especially the birthday boys.
