It was a record-breaking night for the Chartiers Valley boys basketball team. But all the Colts did was break their own record.
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 in 2005 against North Allegheny.
Cousins Matty McConnell (pictured) and Jerrad Tuite both scored 22 points and both made six 3-pointers. Jake Ritson had four 3-pointers and 12 points while Eddie Flohr had 14 points.

In each of the past two seasons, the Upper St. Clair girls were the lower-seeded team when it ended Hempfield's season.
On Tuesday night, the roles were reversed and the Spartans got their revenge.
Hempfield (15-8), the No. 12 seed, led by as much as 20 in the second half and held on for a 65-56 victory against the No. 5 Panthers (14-7) in a Class AAAA first-round game at Bethel Park.
Two seasons ago, the 14th-seeded Panthers beat No. 6 Hempfield in the quarterfinals, and a year ago No. 13 Upper St. Clair beat No. 4 Hempfield in the first round.
But on Tuesday, the Spartans led, 35-18, at halftime and held its largest lead at 50-30 with 3:48 left in the third quarter. Upper St. Clair closed the gap to five, 57-52, with 1:53 left in the game, but got no closer.
Monica Burns led Hempfield with 19 points, while Constance Raftis had 19 for the Panthers.
