AURORA | The Colorado High School Activities Association released the initial set of Ratings Percentage Index (RPI) Class 5A standings Tuesday and Regis Jesuit sits in the No. 1 spot.

Coach Jim Soran’s Raiders — undefeated in three Colorado games, including a 13-12 win over Cherry Creek and 4-1 overall after a 1-1 trip to California — hold a solid edge atop the classification’s 40-team RPI standings, which are used to determine the playoff field.

The RPI formula is a weighted blend of a teams’ winning percentage, opponents’ winning percentage and opponents’ opponents’ winning percentage. The standings change daily based on results.

Regis Jesuit returns to action with a big one against Mountain Vista (No. 15 in the initial standings after just two games) at 6 p.m. Wednesday at Shea Stadium.

Joining the Raiders in the top 10 among local teams is Grandview, which completed a 2-0 swing to Utah over Spring Break.

Coach Patrick Chapla’s Wolves are 2-4 overall and hold the No. 9 position thanks to an early season slate that has seen them already take on No. 2 Columbine, No. 5 Arapahoe and No. 11 Kent Denver, with No. 7 Colorado Academy to come at 4 p.m. Wednesday.

Cherokee Trail (1-3, No. 19), Smoky Hill (1-6, No. 20), Eaglecrest (2-4, No. 22), Overland (0-6, No. 36) & Rangeview (3-2, No. 37) round out Aurora’s representation in the 5A RPI standings.

The Raptors are the only team in action Tuesday with a contest against Denver South.
