The rematch is on — between two teams becoming quite familiar with each other.

Butler (19-4) rides a 14-game winning streak into Saturday night's WPIAL Class 6A boys basketball championship game against Mt. Lebanon (18-6) at the University of Pittsburgh's Petersen Events Center.

Tip-off is scheduled for 9 p.m.

“After we played them (in December) at their place, I was hoping we'd see them again,” Blue Devils' coach Joey David said. “I'm not surprised it's under these circumstances.”

The Golden Tornado defeated Mt. Lebanon, 75-71, in their regular season meeting. Ethan Morton had 28 points, 15 rebounds and six assists in that game. Raine Gratzmiller had 15 points and seven rebounds, Devin Carney 10 points and Charlie Kreinbucher eight points and eight rebounds for Butler.

Blaine Gartley scored 18 points, grabbed nine rebounds, had eight assists and four steals for Mt. Lebanon. Jake Reinke added 16 points, Jake Hoffman 13.

Gartley and Hoffman are the two returning starters from the Blue Devils team that defeated Butler, 62-57, in last year's WPIAL title game. Mt. Lebanon handed the Tornado an 87-60 loss in the regular season a year ago.

“They are a seasoned team that can do a lot of things,” Butler coach Matt Clement said. “These coaches we're facing in the playoffs, Danny Holzer (Upper St. Clair) and Joe David, they've been two of the best in Western Pennsylvania basketball for a long time.”

When Mt. Lebanon defeated Butler in the finals last year, 62-57, it marked the Blue Devils' first WPIAL title in nine years. Butler has not won a WPIAL boys basketball championship since 1991.

Clement has been part of five of the Tornado's six title game appearances since 1991. He was a sophomore on the 1991 championship team, a senior on the 1993 WPIAL finalist squad.

He, of course, has coached Butler to the finals in 2017, last year and this year.

“The only one I missed was 2000, Ben Gallagher's year,” Clement said.

Butler lost to Penn Hills in the finals that season.

Mt. Lebanon has a senior-laden starting lineup this season. Hoffman is a 6-foot-3 senior who scored 19 points, had five rebounds and six steals in last year's championship game. Gartley is a 5-10 senior guard, Joey King a 6-4 senior forward and Andy Sapp a 6-3 senior starter. The other starter is 6-3 junior Reinke.

Two of the top three players off the bench — Danny Simburo and Tommy Peters — are seniors as well.

“We started a few seniors last year, but we had a deep team and I knew we'd have a good group coming back,” David said.

“I see Butler as being pretty similar to last year's team. Of course, they don't have (Luke) Patten, who's a great kid and a great player. It's to their credit they've been able to overcome that.”

The two teams won radically different semifinal games. Mt. Lebanon stifled Central Catholic, 48-32, while Butler won a wild 83-78 overtime game over Upper St. Clair.

“Both teams were held to six points in the second quarter,” David said of his team's semifinal win. “Besides that, it was a normal high school basketball game.

“We can certainly get up and down the floor. Both teams will be ready for this game. Playing in that last venue (UPMC Events Center at Robert Morris) was good preparation for both of us for this venue.

“You just can't over-think things, You play the way you played to get you here. Just go out and play the game,” David added.

Morton had 21 points, 14 rebounds and six assists against the Blue Devils in last year's title game. Carney added 13 points, Patten 12.

Butler rallied from five-point deficits with less than a minute to play in both of its two WPIAL playoff games this year.

“This team's mettle has been tested many times,” Clement said. “Really, it started with losing Luke in the preseason. People overlook the fact we haven't had him on the floor all year.

“I get a little nostalgic at this time of year. I don't know what's going to happen Saturday, but getting to the finals for a third time in four years, going unbeaten and winning the section ... These kids have accomplished a lot.

“Seeing the maturation and development of our players ... Devin is such a great offensive player, but does other things for us to help us win. Mattix has gone from being an outside shooter to a scrappy rebounder and great defensive player, Mason Montag has played so many roles in his career. It's been fun to watch that type of growth,” Clement added.

One of these teams will have fun celebrating a WPIAL championship.

“They don't have a big man, but they have a lot of guys who can rebound and so do we,” David said. “This is going to be a battle.”
