TX HS pitch limits?

[SAump]

Spectator at best of three TX high school baseball south region playoff game. Visiting Team A wins game one 4-o Friday night. Visiting Team B wins game two 4-1 on Saturday. Team B decides to start game two winner for game 3. Pitcher threw 7 innings in the previous game 2. None in Friday game 1.

Controversy to begin top of 4th follows. Apparently, Coach for team A meets with the umpire and wants the team B starting pitcher removed from the game. Coach A states that TX UIL rules limit high school pitchers to ten innings in two consecutive games on one calendar day, the double header now played. The umpire, after lengthy delay, continues the game. Two outs into the inning, Coach A returns with a cell phone in his hand. After another lengthy delay and a phone call to Austin, the pitcher and the two outs are removed from the board. Anyone here know of this rule?

Team A scores one run after the previous two batters return to the plate for the second time that inning. Five outs sounds unfair? Score now 3-1, coach A now returns his starter from the previous night who is allowed to complete the game. Apparently, throwing more than ten innings on two consecutive days is still allowed by UIL rules.

The thing is no one around here has ever heard of this pitching limit placed on high school players. Last game of his senior year and he has been asked to rest, to save his arm, to prevent injury? Team B loses 5-4. Personally, UIL should overturn a game decided by a coach after watching a young man carve up his team for ten innings that day. Any comments about the rule limiting high school pitchers from throwing two complete games in one day during a three game playoff series.
