Covenant Academy is excelling at winning the games that matter the most.The Lady Lion volleyball team kept its record perfect in Middle Tennessee Athletic Conference play Tuesday at home, downing visiting Lancaster Christian 25-4, 25-13 and 25-18. The win improved Covenant to 7-7 overall but, more importantly, 4-0 in conference play.Coach Chris Madewell has challenged his team with a stacked schedule early, hoping it would pay dividends when the team got to the conference tournament. His plan seems to be working, with Covenant fighting back to defeat West Academy on the road last week before dominating Lancaster at home.“I feel like we’re maturing as a team with each game we play,” Madewell said after last week’s win over West Academy.
