This has nothing to do with FPSB and I don't expect anyone to have an answer (wrong board) , but putting it out there...

In MLB low pitch, skips into catcher's mitt.
New baseball.
Why? Dirt puts a spot on ball which batters don't like.

Just watched the first inning of Mil-Atl.
Whole half-inning with the same baseball!

Two of the outs were ground outs where ball hit on the infield dirt, but the same ball stayed in the game.
Seems like there would be "spots" on the baseball, but there was no "ball rotation".

Doesn't this sound a bit contradictory?
