Two-time champion Phil Mickelson and Masters winner Bubba Watson have committed to play in the Waste Management Phoenix Open.

The news of the popular PGA players’ participation should be an economic boost for business. The 2012 Waste Management Phoenix Open pumped $222 million into Arizona’s economy — with direct sales tax revenue estimated to be $8.2 million — and non-local attendees spent an average of $300 per day.

Defending champion Kyle Stanley, 2011 winner Mark Wilson and 2010 champion Hunter Mahan also are entered in the Jan. 31-Feb. 3 event along with Rickie Fowler, Nick Watney, Carl Pettersson, Nicolas Colsaerts and Lucas Glover.

Mickelson won at TPC Scottsdale in 1996 and 2005. The former Arizona State star will open his season Jan. 17-20 in the Humana Challenge in La Quinta, Calif.
