CORAOPOLIS — It can't be called March Madness, but February Frenzy will work.

The WPIAL boys and girls basketball tournament commences this weekend and teams received their opening-round opponents and sites at a meeting Tuesday night at the Embassy Suites.

This year's tournament includes 158 of the 264 WPIAL teams.

"We have to play 150 games between now and Feb. 23,"said Tim O'Malley, WPIAL executive secretary. "We're playing 61 of those games this weekend."

None of those 61 games will be in Butler County, but all six county qualifiers will be in action this weekend.

The Butler boys (13-8), in the tournament for the first time since reaching the Quad-Afinals in 2000, take on Norwin (18-6) at 8 p.m. Friday at North Allegheny.

"We figured we might get them, so I've already seen them play and we've got three tapes on them,"Butler coach Joe Lewandowski said. "They are an extremely athletic team.

"Mike Shanahan is headed to Pitt and has gotten football and basketball offers from major schools. Tyler Urban is headed to Maryland for football — and neither one is their top scorer."

Before dropping a 73-68 decision at Greensburg Salem Monday night, Norwin had reeled off 10 consecutive wins.

"We were seeded around 10th, a little higher than I anticipated,"Lewandowski said. "Maybe the panel looked at our injuries and strength of schedule."

The Golden Tornado girls (22-2) were seeded third in Quad-A and take on Hempfield (18-6) at 3 p.m. Saturday at Plum. The Spartans have won six of their last seven.

Butler could face powerhouses Peters Township and Mount Lebanon in the quarterfinal and semifinal rounds, respectively, should they keep winning.

"It makes no difference, really,"Tornado coach Dorothea Epps said. "Everybody's good at this point and we're all starting over anyway."

Butler was hoping for a boys-girls doubleheader, but didn't get one.

"At least we're on different nights,"Epps said. "Hopefully, people will come out and support both teams."

Seneca Valley did get a boys-girls doubleheader, which is slated for Saturday at North Hills.

The Raiders boys (17-7) set a school record for victories in a season and take a three-game winning streak into a 1:30 p.m. matchup with Upper St. Clair (19-5). The Panthers have won seven of their last nine.

The Seneca Valley girls (10-14) drew top-seeded Norwin (23-1) in a 3 p.m. tip-off Saturday. The Knights are coming off their lone loss, a 66-53 decision to Woodland Hills Monday night.

"We're the only Quad-A girls team in the field with a losing record,"SVcoach Kelly Mathews said. "I figured this would happen.

"We played a tough nonsection schedule with hopes of getting into the playoffs. Now we're in and, hopefully, that schedule will pay off. We're used to top-flight competition."

The Mars girls (11-12) are used to fighting for their playoff lives. The Planets won three of their final four section games to reach the tournament.

The Planets take on Franklin Regional (10-14), loser of four of its last five, at 3 p.m. Saturday at Gateway.

"We feel like we've already been in the playoffs for two weeks,"Planets coach Tony Howard said. "We've got a young team and only one of our players, Lily Grenci, has any playoff experience.

"We've discovered our identity in these last two weeks, though. We've become a pressure, score in transition team, and we're playing well right now."

Summit Academy (11-11) qualified in boys Class AAand plays Quaker Valley (15-9) at 8 p.m. Friday at Aliquippa.

The Knights had won five of six games before losing 59-56 and 66-65 to St. Joseph and Neshannock, respectively, to close the regular season.
