The top high school baseball division in Arizona is down to just four teams. It's state tournament time, and the AIA 6A bracket is headed to the semifinals on Friday.
The four teams remaining are the top four teams ranked on MaxPreps' Arizona baseball rankings. Corona del Sol, Hamilton, Casteel and Red Mountain are the final four, ranked in said order.
That group has plenty of championship pedigree, as Hamilton won the 6A title in 2022 and 2023, while Casteel took the 5A crown the last two years before moving up to 6A this season.
Both games will take place at HoHoKam Stadium in Mesa, the spring training home for MLB's Athletics, with the winners advancing to Tuesday's final at the Angels' spring home, Tempe Diablo Stadium.
