Moments: Tipped Pitches?

I've been playing a lot of Moments recently, having barely played any all season previously. During my at-bats in Moments, I've noticed a sound identical to the sound made when clicking through menus. Over time, I've come to realize that the sound plays only when the CPU pitcher selects his primary pitch. Anyone else notice this?

Baltimore Chop

It occurred to me a few minutes ago that one hit type I've not seen in any game all season is the famous "Baltimore Chop", a grounder which hits home plate and soars high above the infield, generating an infield single most of the time. Anyone else notice this absence?
