The 3-point line came into Pennsylvania high school basketball in 1987.
In the 27 seasons since then, no team shot 3-pointers in a WPIAL playoff game like Chartiers Valley did Tuesday night.
Chartiers Valley set a WPIAL playoff record when it made 21 3-pointers in a 95-62 victory against Mount Pleasant in a Class AAA first-round game at Peters Township.
Chartiers Valley (22-1), the Post-Gazette's No. 1 Class AAA team, made 54 percent (21 of 39) from 3-point range and broke its own playoff record of 15, set against North Allegheny in a 2005 quarterfinal.
Against Mount Pleasant, cousins Matty McConnell and Jerrad Tuite both scored 22 points and both made six 3-pointers, one away from the Class AAA individual playoff record. Jake Ritson had four 3-pointers and 12 points while Eddie Flohr had 14 points.
Luke Liprando had 22 points for Mount Pleasant, which lost its first playoff game for the 10th time in 12 appearances.
