The PIAA has strict rules when it comes to how many innings a player may pitch in a day or a week. Following is the PIAA Baseball Pitching Restriction guidelines (6-1-6):

✓ A player may pitch in a maximum of 9 innings in 1 calendar day, but not more than 14 innings in a calendar week (Sunday through Saturday).

✓ Delivery of one 1 pitch constitutes having pitched in any inning.

✓ If an inning is played in part on 2 calendar days, delivery of 1 pitch in that inning in each of those calendar days constitutes having pitched in 2 innings.

✓ If he pitches in 3 innings or less in 1 calendar day, no rest is required; however, no player may pitch more than 3 consecutive three-inning days.

✓ If he pitches 3 consecutive three-inning days, he must have 1 calendar day of rest.

✓ If he pitches in 4 or 5 innings in 1 calendar day, he must have 2 calendar days of rest.

✓ If he pitches in 6 or more innings in 1 calendar day, he must have 3 calendar days of rest.

✓ If a baseball player pitches more innings than are permitted under the “restriction” the school is using an ineligible player (pitcher) and shall forfeit the Contest. Violations ofthe “restriction” subject the school to other penalties under ARTICLE XIII, PENALTIES, of the PIAA By-Laws. As is the case with all PIAA rules and regulations, it is theresponsibility of the Principal to make sure that the school’s baseball Coaches and players comply with the PIAA baseball pitching restriction (6-1-6).
