Since the WPIAL switched to more than one classification in 1979, only four baseball teams have won WPIAL titles with undefeated records. Here is a look at those teams:
1979 Freeport (17-0): The Yellowjackets' baseball program was stopped in 1976 but resurrected under coach Bob Eisenberg. Freeport won two 11-inning playoff games to reach the title game, and Brian Marcy pitched 20 1/3 innings in those games. In the Class AA title game at West Field in Munhall, Dino Aimino pitched a five-hitter and also had a double in a 5-3 victory against Chartiers-Houston.
1993 Canevin (20-0): Canevin, coached by the late Red Locke, was fairly strong offensively, with hitters such as Jake Nea and Keith Bittner. But pitcher Brad O'Malley unquestionably was the star of the team. O'Malley pitched a two-hitter and struck out 14 in a 7-0 victory against Apollo-Ridge in the Class AA title game at Pullman Park in Butler. After the title game, O'Malley had pitched 55 1/3 innings and allowed only 14 hits, two runs and struck out 121. Pat Naughton had three hits in the title game.
2007 West Allegheny (23-0): Bryan Cornell won a WPIAL title as a player at West Allegheny and this was a "perfect" title for him as coach. West Allegheny won the title with a 6-3 victory against Blackhawk in the Class AAA championship at Consol Energy Park. Zak Sinclair pitched a five-hitter, struck out 11 and also drove in a run for the Indians. Jared Littler and Rick Deveraux batted better than .400 for the season.
2011 Elizabeth Forward (21-0): Coach Frank Champ's Warriors breezed to the WPIAL title, scoring 33 runs in three playoff games and defeated Hampton, 7-0, in the Class AAA championship at Consol Energy Park. It was the Warriors' first WPIAL title since 1976. Dan Altavilla pitched a two-hitter and struck out 10 in the championship, lifting his record to 10-0. He had a no-hitter until the sixth inning. John Kutzfara and Cody Shotwell both had three hits and Shotwell hit a two-run homer.
