Jason Day, Ernie Els, Padraig Harrington commit to Nelson

A couple of former major winners and past champions have committed to the 2012 HP Byron Nelson Championship May 14-20.

Ernie Els, winner of three majors (two U.S. Opens and a British Open), Padraig Harrington, also a three-time major champ (two British Opens and a PGA) and Jason Day, winner of the Nelson in 2010, are going to play in this year's event.

Those three join other recent commitments: Ben Curtis (winner last week in San Antonio and the 2003 British Open) and Jason Dufner (No. 23 on the PGA Tour Money List).

The tournament will be played at TPC Four Seasons Resort in Las Colinas.
