Etymology
Ball and park first named a sports ground. The approximate sense evokes broad but reasonably predictable bounds, perhaps originally referring to a missile’s expected landing area.
In context
set something in the ballpark of around 1850 megahertz and 860 millivolts there you will get quite a noticeable reduction in power and thermals with no real impact on gaming performance
More examples
