When I walk around a practice green on the PGA Tour, I can usually tell right away who’s putting great. You can see everything in the finish. Guys who are putting awesome accelerate through the ball, so the putterhead and the lead shoulder finish low and forward. Even on soft, short putts, an assertive stroke is immediately recognisable. On the other hand, guys who are just hoping to make putts tend to let the putterhead and front shoulder rise after impact. It’s like you can see them backing up to watch, curious about where the ball goes. A strong, low finish with the putterhead isn’t something I think about during my stroke; it’s just a universal tendency I’ve noticed among the best. As I said earlier, I don’t think about anything when I’m in blackout. It’s a place where you suddenly arrive after a lot of gradual preparation. Though sometimes none at all.
