8. 1 pitch per inning for 8 innings if the pitcher is on the home team.

Here's how - 1st batter in the inning hits the first pitch for a single. Instead of returning to the mound, the pitcher hands the ball to the catcher who stays behind the plate. If, for no good reason, the runner at first tries to steal second, then the catcher tries to throw him out but the next batter interferes, the batter is called out and the runner returns to first. Repeat until there are 3 outs in the inning. 1 pitch, 3 outs.

Realistically the answer is 24. 1 pitch per out for 8 innings by the home team pitcher.
