Phil Mickelson and his longtime swing coach Butch Harmon have split, according to a statement Mickelson sent to Golf.com on Wednesday.
"I've learned a great deal from him in our eight years together," Mickelson said in the statement. "It's just that at the moment I need to hear new ideas from a different perspective."
