Michelle Wie: who's your caddy?

On Golf Academy Live, David Leadbetter, coach to Michelle Wie, revealed the following humorous story:

Michelle fired her caddy after the first round of the Evian Masters, and switched back to her father BJ Wie. Apparently, BJ gave Michelle the wrong yardage by +30 yards on Hole No. 4, which caused Michelle to airmail the green and go on to triple bogey the hole. That got Michelle mad, so she proceeded to birdie 6 of the next 8 holes.
