Chartiers Valley looked poised to become the first team since December to knock off Upper St. Clair, jumping out to a 13-2 lead Monday on its home floor.
But Jordan Grabowski and the Panthers had other ideas.
Grabowski hit four 3-pointers in a big second quarter for Upper St. Clair and finished with 29 points as the Class AAAA No. 2 Panthers (19-3) beat Class AAA No. 2 Chartiers Valley (19-3), 77-68.
After trailing, 22-8, at the end of the first quarter, Upper St. Clair cut the deficit to five by halftime.
With the Colts lead at three midway through the third quarter, Grabowski scored seven points in an 18-3 Panthers run that gave the visitors a 55-43 lead in the opening minute of the fourth quarter.
J.J. Conn added 23 points for Upper St. Clair, which will enter the WPIAL playoffs on a 16-game winning streak.
Michael Boulos led the Colts with 20 points, and Spencer Casson finished with 13 points, nine rebounds and six blocks.
