With the opening of baseball season, this title brings to mind the summers when my boys were playing baseball. Ducks on the pond may be something you see in your backyard or at a park; ducks are also on the pond at most every baseball game played. Ducks refers to base runners and pond refers to the bases.
For those not familiar, this term is typically used by the offense when cheering on a hitter to drive in a few runs. It can be said in a state of relief (We finally got some ducks on the pond) or in a situation where runs are needed (Let’s go! You got some ducks on the pond!). Either way, you know that there are runners on base who are ready to cross home plate and score some runs. They don’t want to be stranded in the field.
So, even though these are geese, they're on the pond!
I seem to be channeling Graham Thresher. We have a pair of geese nearby and if I"m lucky and hear them honking as they approach our neighbor's pond, I can usually stalk them for a while.
