On Oct. 25, Parker McLachlin set a PGA precedent -- he became the first golfer to Tweet during a PGA event.
''Just made birdie on 4. Waiting on 5th tee. First tweet during a tourney round. Don't want to get too used to this!'' (1:28 PM Oct 25).
Don't expect it to happen very often, however. McLachlin received a call from Tour executive VP Rick George, telling him that he was violating the rules.
