One of the biggest names on the PGA TOUR will have a new golf ball in play at the Farmers Insurance Open after TaylorMade Golf confirmed that Dustin Johnson would be using the company's new Lethal ball.

Johnson had been playing TaylorMade's Penta TP5, but following his win at the Hyundai Tournament of Champions, he decided to open testing again with the Lethal.

After working with it for the last couple of weeks, Johnson finally felt comfortable enough with the ball's performance in the scoring zone to make the switch official at Torrey Pines.
