I agree with the strategies outlined above, however, your best player may not be your longest driver. You may want to occasionally move your best driver to the 3rd spot to keep pressure off of him. Swap up the 4th spot.

Watch your first putter carefully to make sure he's making a good swing and not cutting across the ball, pushing, pulling, etc. Otherwise, you won't get a good read from his attempt.

Remember, in these scrambles birdie = par. To have any kind of chance, your team will probably have to come in 15 - 18 under.

Since this is a church scramble, I'm assuming no alcohol is involved?
