My best days in golf were when I spend most time practising putting. I hated it. The practise green near my home were bumpy and wet but I would just persevere and try to get the stroke right.
Interestingly, if I get my putting right, the rest of my game just fall in places. I cannot explain it but maybe it has to do with getting my rhythm right. I cannot be sure.
I also watched how the tour players spend their time before their designated tee off time and noticed that they spend most times putting or chipping. In the range, most times were spent on wedge. Strangely, they spend the least time on drivers and woods, perhaps only 2 or 3 shots at the end to cap the practise.
Different strokes I guess. I'm the exact opposite. My game lives or dies with my driver. If I'm hitting it well and finding fairways, I'm generally par or birdie. Today for example I hit five straight fairways to start the round and played those holes in one under. Started missing to the right after that and finished the day 11 over.
My guess re pros practice routines is that they spend a disproportional time on putting and chipping because its based so much on feel and touch. For the longer clubs, those guys swing are so dialed and consistent it's not like they're going to get out on the course one day and completely lose it.
