Jack Nicklaus has jumped into the golf ball business. Production begins this month on a line of three different models—Nicklaus Black, Blue, and White—geared to the skill levels of golfers (the colors refer to the tees from which better, average, and weaker players traditionally play). The balls, three years in development according to Jack’s specifications, will be produced by Bridgestone. They’ll be available in November but initially only online from Jack's website and through pro shops at Nicklaus-designed courses. A percentage of sales will go to the Nicklaus Children’s Health Care Foundation. And despite Jack’s longtime belief that the golf ball should be “throttled back,” rest assured, these will be full-octane models.
