No. 1 Cardinals shut out St. Mike’s

Friday night’s marquee matchup left little doubt as to which side is the No. 1 team in the new Class 4A.

Top-rated Robertson dominated visiting St. Michael’s — ranked either second or third in the polls this week — by a 20-0 count to remain undefeated at 4-0. The Horsemen, whose resume had included wins over Taos, Santa Fe and Capital, slid to 3-1.
