I was there on Monday. I was 3-putting and 4-putting the whole day. What a time to choke, too! (J. C. Championship) I even greened the par-3 6th hole...I walked away with a 5. What a disappointment. Then Tuesday, after a little focus, a little practice and a little sleep (very little sleep), I was hitting beautifully. Putts started going in. Chips came close. Drives went far. Everything was on at one point or another in the round, and produced an 87 round that I was very proud of, even if it was a par-61 course.
Just settle down, swing, and watch as everything (albeit eventually) comes together. That's my best advice (maybe I should follow that advice once in a while)
