Look up the word dominant, and you likely will read a definition that states something such as, commanding, controlling, or prevailing over all others.

If there were a photo next to it, you might be surprised at what it looks like.

It could be a snapshot of the Mt. Lebanon girls' basketball team.

In what already has been a magical season, the Blue Devils reached a new peak last night, putting together a dominating, 50-24 victory against Fox Chapel in the WPIAL Class AAAA girls' championship game at Palumbo Center.

It's the first time in school history the Blue Devils have earned the WPIAL's top prize.

"It's amazing. I don't even know what to say," Mt. Lebanon senior forward Emily Miller said.

Miller wasn't the only one at a loss for words. On a night filled with plenty of amazement and history, a few marks stood above the rest, facts that have given the Blue Devils the title of being one of the best WPIAL girls' teams in recent memory.

At 26-0, the Blue Devils became the first girls' team to win a WPIAL championship with a perfect record since Avonworth did it in 2005.

And, while that mark came during a three-month stretch, their single-game accomplishment was quite impressive, too. The 24 points the Blue Devils' suffocating defense surrendered was the lowest point total by a team in WPIAL Class AAAA championship history.

Asked if she had expected anything like the performance her team provided, Mt. Lebanon coach Dori Oldaker quickly replied, "Not even a thought in my mind."

Only two teams have come within 10 points of Mt. Lebanon this season, and the Blue Devils gave up no more than 32 points in any playoff game.

The defense was the talk of the gym last night, stifling Fox Chapel (20-5) from start to finish. The Foxes connected on only 2 of 13 field-goal attempts in the first quarter, quickly falling behind, 13-4. And from there, it snowballed.

The Foxes finished the first half with 10 points. For the game, Mt. Lebanon limited Fox Chapel to 23 percent shooting (10 of 42), including 2 of 14 3-pointers, while forcing 18 turnovers.

"They really get after it on the defensive end. I thought we made some unforced errors, some goofy mistakes here and there. But, of course, their defensive pressure, it's difficult to simulate in practice," first-year Fox Chapel coach Rich Mull said.

Offensively, the Blue Devils showed off their typical well-balanced attack. The second-highest scoring team in Class AAAA connected on 17 of 37 field-goal attempts and 15 of 24 free throws, placing three players in double figures -- junior Lauren Arbogast (14), Miller (13) and sophomore Madison Cable (11). The Blue Devils always seemed to make that extra pass and also pounded the glass, outrebounding the Foxes, 30-18.

Even when Fox Chapel made a run, Mt. Lebanon earnestly widened the margin again. Such was the case in the third quarter, when the Foxes pulled within 29-19.

The Blue Devils, though, responded with a 13-0 run to finish off the Foxes.

"Our kids are never satisfied, and that's what's great about them," Oldaker said.

It was the third WPIAL championships for Oldaker, who is in her sixth season at Mt. Lebanon. She won two WPIAL and PIAA Class AAA titles at Blackhawk.

Fox Chapel, which never had played in a WPIAL semifinal before this season, was led by senior Heidi Goeller's eight points.
