DETROIT — It was business as usual at the CHSL wrestling championships last Saturday.

Novi Detroit Catholic Central overwhelmed a field of eight other schools to win its 18th consecutive CHSL title.

Team standings 1. Catholic Central (CC) 279.50; 2-tie. DeLaSalle (DLS) and U-D Jesuit (U-D), 154; 4. Brother Rice (BR) 150; 5. Dearborn Divine Child (DC) 147.50; 6. Orchard Lake St. Mary’s (OLSM) 63; 7. Notre Dame Prep (NDP) 43; 8. Madison Heights Bishop Foley (BF) 39; 9. Riverview Gabriel Richard (GR) 21.

The Shamrocks won 36 of their 43 matches to rack up 279.5 points, nearly doubling the 154 of co-runners-up Warren DeLaSalle and Detroit U-D Jesuit, which hosted the event.

Two champions from a year ago successfully defended their titles: Pontiac Notre Dame Prep’s James Yanik in the 171-pound class and CC’s Robert Coe in the 285-pound rank.

Two other 2011 champs won again this year, but at a different weight: Andrew Napieraj, of Bloomfield Hills Brother Rice, won the 135-pound title to go with last year’s 130-pound crown, and CC’s Alex Goings, a 135-pound champ last year, won the 140-pound title.
