DeChambeau earned the silver cup as the low amateur at the 2016 Masters, and spent a considerable amount of time deciding which ball would help him compete at the highest level on Tour.
"I take every part of my game seriously, and it was clear after a thorough review that Bridgestone Golf's Tour B330-S was the best fit for me," DeChambeau said. "I'm excited to be a part of Bridgestone's team and benefit from the precision they put in to each and every ball made."
