Which pitches are strikes?

[cc6]

Camera angle:
I thought the angle was good. What would be a better angle?

FYC:
If it was, why didn't the umpire not pull the trigger with a bit more aggression on the third pitch?

League:
If it's a professional league, hitters should be able to hit the outside pitch the other way. That being said, the first two were very hittable, and the third could have been fouled off by a good contact hitter.

I think that by working in the slot, we develop a slightly larger outside corner. I think a lot of umpires routinely call the 2nd pitch a strike.
