Phil Mickelson will continue to play Callaway golf clubs after the five-time major winner signed a multiyear extension Thursday.
As a staff pro, he will continue to play Callaway clubs as well as the company's golf ball and carry a staff bag.
Mickelson, who joined the golf manufacturer 10 years ago, feels the association will put him in the best position to improve upon his Hall of Fame credentials.
"I honestly believe that these next few years will be the best of my career," Mickelson said in a statement.
