Sources have told Rosaforte that the relationship will be made official before the upcoming EDS Byron Nelson Championship. Mickelson is scheduled for a press conference Wednesday in Irving, Texas.
Mickelson has been downplaying rumors that he was going to switch to Harmon from long-time coach and good friend Rick Smith. Harmon was seen working with Mickelson earlier in the year before the WGC-Accenture Match Play Championship. After the Masters Tournament, Mickelson told Golf World, No, nothing has happened, in regards to a coaching change, everythings the same.
The switch is supposed to help Mickelson straighten out his driver. He is averaging 296.5 yards off the tee, down from 300.7 a year ago, but is hitting only 58.8 percent of his fairways, ranking him outside the top 125 on the PGA TOUR.
Mickelsons driving woes were most evident at last years U.S. Open, where a pushed drive on the final hole led to double-bogey and cost him a chance at his third straight major championship victory. He also hit a poor tee shot on the 72nd hole at this years Nissan Open, which led to a bogey. A par would have won him the tournament; he eventually lost to Charles Howell III in a playoff.
Harmon was the instructor for Woods when he won his first eight major championships. Woods has been working the last couple of years with Hank Haney.
