The Warren County High School boys basketball team set out to prove Saturday it wasn’t just happy to be in the regional tournament. Even with the Pioneers out to show they belonged, the Walker Valley Mustangs proved to be hostile hosts in the Region 3-AAA tournament.The Pioneers’ season ended in the regional tournament for the third time in four years as Walker Valley defeated Warren County 62-46 Saturday night.Warren County (13-21) has slowly progressed in the regional tournament under coach Malcolm Montgomery, but the improvement didn’t result in a victory over the Mustangs.The Pioneers were destroyed by Cleveland three years ago, losing by 57. Two years ago, Warren County went toe-to-toe with McMinn County for a half before falling by 19.Coach Montgomery went into Saturday’s game leaving the team’s past performances behind and hoping to get the best 32 minutes of basketball from his Pioneers.While the Mustangs put the game away with a late run, coach Montgomery believed his team had nothing to be disappointed with when leaving Cleveland.“We walked out of their gym with our heads held high,” said Montgomery.
