Karlie Samuelson and Brittany McPhee combined for 38 points and the 13th-ranked Stanford women's basketball team used a scintillating third quarter to complete a weekend sweep, beating Colorado, 84-70, Sunday.

Stanford (15-3, 5-1) was down, 42-41, at halftime and missed its first two attempts coming out of the break but closed the period with Samuelson and McPhee making nine consecutive shots.

Samuelson nailed a pair of 3-pointers as part of a 9-0 run to put Stanford up 50-42 with 6:36 on the clock.

She made another from distance and tacked on three free throws two minutes later to increase the lead to 10 before Colorado (11-6, 1-5) responded with back-to-back 3-pointers and that's when McPhee took over.

The junior scored 11 straight points for the Cardinal over the quarter's final 2:36. McPhee sprinkled in a corner triple with acrobatic layup after acrobatic layup, knifing through the Colorado defense.
