Simpson and world No. 1 Luke Donald are vying for the PGA Tour money title and both have said they will play this week at Disney, the tour’s final event. Simpson trails Donald by $68,971, but could move into the top spot with a strong round today. Donald also leads the European Tour money list.

Simpson is looking for a tour-leading third win this year, which could make him the favorite for PGA Tour Player of the Year.
