Dustin Johnson, Caddie To (Finally) Split

Shocking to believe after the PGA debacle and a near missed tee time in LA, but Dustin Johnson and caddie Bobby Brown have decided to spend less time with each other, reports Tim Rosaforte.

In a move that comes as a surprise, Brown and Johnson have split up. Brown, who is dating the sister of Johnson's girlfriend, initiated the dialogue and both have agreed it's better to move on. They started working together in the middle of Johnson's 2008 rookie season and have been together for four victories, including two AT&T National Pro-Ams and the 2010 BMW Championship.

"This is part of the game and we both understand that," Brown said Tuesday.

Johnson, a native of Myrtle Beach, S.C., is not playing in this week's Heritage in Hilton Head, S.C. David Winkle, Johnson's agent, said the breakup was "mutual," adding, "I guess only time will tell if their break proves to be temporary or permanent."
