Phil Mickelson was spotted working with swing coach Butch Harmon before the WGC Accenture Match Play Championship in Arizona. That wouldn’t normally be cause for news, but Mickelson already has a swing coach in Rick Smith. The timing is interesting, considering Lefty went left again on the 18th hole at Riviera on Sunday. He had a one-hole lead with one hole to go, needing only a par to win the Nissan Open. He bogeyed the hole, then bogeyed the third playoff hole and lost to Charles Howell.
