K.J. is OK ... for awhile

K.J. Choi birdied the first three holes Friday to move into the lead at 5 under in the Chevron World Challenge.

His lead was short-lived, however. Choi had a bogey on the fourth hole, a double-bogey on the sixth and a bogey on the eighth to drop back to 1 under, three shots behind co-leaders Jim Furyk and Boo Weekley.
