Twenty-four players put one in play the first week it was available on tour — Tom Hoge, Matt Wallace, Jhonattan Vegas, Johnny Keefer and Jeff Kang among them. The GTS2 alone accounted for 18 bags, tied for most-played model at the event. Titleist isn't discussing the technology just yet, but multiple players Golf Digest observed on the Houston range were seeing 1-3 mph ball speed gains. Charley Hoffman, who made the switch to GTS2, says the off-center performance is a big reason why. "If you know the off-center hits are going to be more consistent, you have the intuition to swing harder at it because you're not scared of the ball going offline." Early standout: Jeff Kang, dead last on tour in accuracy, hit 11 of 13 fairways on Thursday. Hard to write that off as a coincidence.
