Is there a list of definitions or something that explains what all of the abbreviations are on the scorecard? I've tried Googling but I can't find many that iScore puts on the scorecard.

So what's "Kd" and "OT3"?

Kd is dropped third strike. OT3 is runner advancing "on the throw" while batter 3 is up.
