It seems each time the Pioneers take the field, heart-stopping action awaits.The Pioneers claimed their third walk-off win – and second in four nights – this season Thursday when Hunter Mullican hit a game-winning double to lift his team to 6-5 victory over Sequatchie County.Warren County (9-8) has been no stranger to late-game heroics this year and Mullican added another moment Thursday night. The senior left fielder celebrated his 18th birthday in style when he hit a 0-1 pitch deep into center field.
