Texas high school baseball playoffs: UIL Class 1A-3A regional matchups, brackets

We've reached regional play in the 2025 UIL Texas High School Baseball Championships. As parity across the state seems to be quite good this season, we had a load of games, and series, go down to the wire last week in the area rounds.
This week features another exciting slate of games, as teams will complete play in the region semifinals. Following this week, Class 1 will be down to its final four teams in each division, respectively, while Class 2A-6A winners will advance to the region finals and will be left with only eight teams standing in each respective class and division.
These regional semifinal series will be completed, weather permitting, by May 17. Check out our pairings below and the brackets beneath that and be sure to follow High School On SI Texas for the latest high school sports news, scores and updates.
