There's a fine line between success and failure in tournament play.
The Mt. Lebanon High boys lacrosse team learned that painful lesson with a 12-10 loss to District 3 runner-up Cumberland Valley in a game played at Hempfield Area Senior High School this past Wednesday.
The loss ended the Blue Devils' season at 15-7, and it came less than a week after Mt. Lebanon defeated North Allegheny, 9-8, in the WPIAL Division 1 championship game at Highmark Stadium.
"Things did not go our way at the end," Mt. Lebanon coach Mike Ermer said. "It was tight for most of the game, but at the end, they were able to convert a couple of looks, and we didn't convert ours."
