As it was expectable Phil Mickelson is continuing to work with Callaway Golf as a Staff Pro. Phil Mickelson has signed a multiyear extension with Callaway Golf. As a Staff Pro, he will continue to play Callaway clubs, a Callaway golf ball and carry a Callaway Staff Bag.
Last year he had 2 PGA Tour wins, 7 TOP10 and 11 TOP25 finishes. In total Phil Mickelson has 42 PGA Tour wins. This is pretty convincing why it is good for Callaway Golf. He is not a problematic professional golfer. Apart from he was implicated in an insider trading-investigation (in June 2014) we hardly hear any scandal around him.
Ian Poulter who recently joined Titleist's PGA Tour Staff has far less impressive results on PGA Tour in 2013 (in total he has got only 2 PGA Tour victory.
