Phil Mickelson, a five-time major winner and three-time Masters champion, announced Tuesday he has split with caddie Jim "Bones" Mackay after working together for 25 years and 41 professional triumphs. The 47-year-old lefthander and the bagman he met at 1992 US Open sectional qualifying in Memphis parted ways as friends, each releasing a statement saying as much. "After 25 very rewarding and memorable years, Bones and I have mutually decided to end our player-caddie relationship," Mickelson said. "Our decision is not based on a single incident. We just feel it's the right time for a change." Mickelson has not won since the 2013 Open Champonship, his fifth major crown after the 2005 PGA Championship and the 2004, 2006 and 2010 Masters.
