With the exception of the Collins incident, all of these go back to someone drilling the pitcher. Pitcher's have to wear full protective gear and still stand out there and let guys hit rockets at them. How are they not going to get pissed?

Something has to change.

Tone down bats/balls
Put a net up
Call outs on anything that touches a pitcher
