The run in the region tournament is over for the Pioneers. Stone Memorial downed Warren County 70-63 in the semifinals Tuesday night, ending the Pioneers’ campaign at 23-8.“We didn’t make the plays down the stretch and Stone just made shots,” said WCHS coach Chris Sullens immediately following the game. The Panthers, who knocked down 16-of-18 free throws in the fourth quarter, advance to Thursday’s regional final against East Hamilton with the victory.
