Catcher moving before the pitcher moves first?

#1

Hi,

I was at the field the other day and I was watching a team intentionally walk a batter and the catcher jumped out of the catcher’s box before the pitcher started any movement to home plate and the umpire called a balk…is this a balk? what should’ve happened?

Yeah that is a balk. The catch is supposed to move after the pitcher has gone into his motion.
