Postseason play in Oklahoma high school baseball really ramps up starting on Thursday.
Several Oklahoma Secondary School Athletic Association (OSSAA) classifications will be conducting baseball regional tournaments. For classes 4A and 3A, it will be the start of postseason play, while classes A-I, A-II and B will continue its playoffs after holding district tournaments last week.
Here is a complete look at the OSSAA baseball regionals this week, with several games shifted to other sites due to inclement weather.
