Completely as an aside, I thought it was going to be about a sales pitch.

Something I'd note is that the major league pitchers are pretty amazing, but I've gone to a few minor league games. In the minors (perhaps depending on the league), a pitcher rarely lasts for an entire game, and their accuracy goes to hell as their arm turns to rubber. Their last one or two pitches before being relieved could go practically anywhere.

The hitters also seem aware of this, and become more wary as a pitcher gets worn down.
