lay out a baseball diamond in a field

Work Up is a sandlot baseball game when you have too few scouts for two teams. Three batters, catcher, pitcher, first, second, third, and two outfielders means you need 10 scouts. But, you can drop second base and a batter and then catcher if needed, or add another batter, shortstop, and center field if you have more.

As long as the three batters get hits and work their way around the bases without getting put out, they continue to bat. When a batter is out, he moves to right field and all fielders 'work up' to the next position with the catcher becoming a batter.

If a fielder catches a fly, he switches spots with the batter that hit it.
If a batter gets some set number or runs, he moves to right field just to keep things moving.
