McAlester can advance to state on Friday.
The Oklahoma Secondary School Activities Association released the Class 5A regional assignments on Monday, and the Lady Buffaloes (13-11) are scheduled to travel to Collinsville.
Thursday's scheduled game against Tulsa Hale in the first round will be McAlester's first game since an Oct. 1 10-0 loss against Oktaha. Monday's scheduled game at Broken Bow was cancelled due to both teams preparing for regionals, according to a Tuesday morning text from McAlester athletic director John Homer.
McAlester only faced one of its three opponents during the regular season: Will Rogers. The Lady Buffs swept a Sept. 17 doubleheader, 30-4 and 18-0.
