Butch Harmon instructing Fowler

Rickie Fowler will be getting a little help with his game from noted instructor Butch Harmon, according to a published report.

Harmon, who coaches several PGA Tour pros including five-time major champion Phil Mickelson, first worked with Fowler prior to his T-8 finish in the Thailand Golf Championship.

"We've shared video [since then]," Harmon told Golf Digest. "He's done good work to clean up things in the swing mechanically."

Fowler won the 2012 Wells Fargo Championship at Quail Hollow in a playoff against Rory McIlroy and D.A. Points for his lone PGA Tour victory. He had been coached previously by Barry McDonnell, who died in 2011.
