BOULDER, Colo. – Chiney Ogwumike had 20 points and 11 rebounds, helping No. 4 Stanford get back on track with a 57-40 win over No. 20 Colorado on Friday night in the Cardinal's first game since losing the top spot in the poll.

The Cardinal (12-1, 0-1 Pac-12) never trailed as they rebounded from a 61-35 loss to Connecticut that not only snapped their nation-leading home winning streak, but ended their six-week run at No. 1.

Stanford's swarming defense prevented Colorado (11-1, 0-1) from getting into any sort of offensive flow, as the Buffs scored just 14 points in the first half — the team's fewest-ever at home. With Colorado's loss, UConn and Duke are now the only undefeated teams in Division I.

Stanford ran its conference winning streak to 79 straight.

Chucky Jeffery led Colorado with 17 points.
