Carlsbad-based Callaway Golf Co. said Sept. 26 that it has extended its relationship with golfer Phil Mickelson. As a result, Mickelson will play with Callaway equipment for the rest of his competitive playing career.

Financial terms of the deal were not disclosed. Lagardère Sports represented Mickelson in negotiations.

Mickelson, 47, joined Callaway (NYSE: ELY) in 2004. Since then, he has won 21 of his 42 PGA Tour titles, including four of his five major championships.
