I feel like I can go to the range, within an hour, I can tighten my ball striking up,

That's what's plagued us. We constantly go on a run to pull within striking range and for some unknown reason we go through a series of making turnovers and allow the team to take off.

We just have to try to tighten up in the middle of defence, because we have to shut the ball down with them,

When we tighten up, that's when we get in trouble.

well within the range of what is realistically possible.

I've just got to be patient. Hopefully I keep striking the ball the way I did today and keep rolling it the same way. There's a lot of golf left.
