ASA Pitcher Delay

[IRISHMAFIA]

Idea taken from another board:

Speaking ASA SP (but could be FP depending on lapsed time)

Umpire calls ball on the batter to take the count full. Unhappy pitcher steps toward the plate and tries to stare down the umpire and intentionally allows the catcher's return throw go into center field.

As no one really chasing down the ball, the umpire offers an open hand toward the pitcher, says, "play ball" and sets up behind the catcher. By the time the ball gets back to the infield, nearly 10 seconds passes. Pitchers snaps off the throw from the SS and stomps around a bit.

Umpire rules ball 4 and awards batter 1B. Defense protests what they believe is a misinterpretation of rule 6.3.

As the UIC, how would you rule?
