us open qualifier, warm springs

was real smooth on the range, and then made a horrible swing on my first tee shot, crossed the line and hooked it into jail. my grip tension probably has something to do with it. i must grab the club at the top of my swing when i'm most nervous. swing on first and last hole in arizona had somewhat of the same feeling.  as day went on, the better swings were shorter, but with wrist cock.  when i really feel the pressure to hit the ball straight, must not cock my wrists.
