The PIAA first-round blues continued Tuesday for WPIAL teams.
Two more went down as West Mifflin lost to Erie Cathedral Prep, 9-2, in Class AAA and Seton-LaSalle lost to Franklin, 7-2, in Class AA. Both games were at Jerry Uht Park in Erie.
Twelve WPIAL teams started the PIAA playoffs Monday and only three escaped the first round. Seneca Valley, Blackhawk and Carmichaels won first-round games Monday and will play in the quarterfinals Thursday.
Against West Mifflin, Cathedral Prep pitcher Carter Cross took a perfect game into the fifth inning before West Mifflin (15-6), the WPIAL's No. 3 team, got a hit from Ryan Catalogna and eventually scored two runs. One run scored on an errant pickoff throw, the other on an infield single.
Sam Riley came on in relief of Cross in the seventh after Cross walked the first two batters and Riley put out the threat.
Cathedral Prep (20-3), the No. 1 team from District 10, took control when it scored five runs in the second off West Mifflin starter Zach Salmon.
In the first game, WPIAL runner-up Seton-LaSalle (15-7) held a 1-0 lead until District 10 champion Franklin (19-2) broke loose for three runs in the third inning. Seton-LaSalle managed eight hits off Franklin starter Zach Guth, but Guth struck out 11. Guth, a junior, has committed to play in college at Indiana.
