PALO ALTO, California (Ticker) -- With Justin Davis back in the starting lineup, Stanford is poised to make a run at the Pac-10 Conference title.
Davis scored 21 points and Josh Childress added 15 as the 24th-ranked Cardinal rolled to a predictably easy 72-54 victory over Washington State.
After missing five straight games due to a partial tear of the his left MCL, Davis had spent the last six games coming off the bench. He started for the first time since January 4 and keyed a solid effort by Stanford, which remained within two games behind first-place Arizona.
Davis made 7-of-10 shots, 7-of-10 free throws and grabbed 10 rebounds as the Cardinal remained unbeaten in 10 games at home and cruised to their 13th consecutive victory over the Cougars, who have not won in the series since 1996.
Washington State was handed its 13th consecutive loss overall and remained winless in 10 road games this season. The Cougars have dropped 19 straight Pac-10 road games.
Childress scored 11 points in the first half, including the final four, as Stanford built a 35-27 halftime edge. The Cardinal never relinquished control after opening the second half with 13 consecutive points.
Childress had two baskets and Davis had a dunk and a free throw during the decisive burst, which gave Stanford (19-6, 10-3 Pac-10) a 48-27 cushion with 14:21 left.
Julius Barnes, who was held to eight points on 2-of-12 shooting, made a layup to give the Cardinal their largest lead at 55-33 with 10:21 remaining.
Stanford shot just 38 percent (26-of-68) from the floor and 2-of-15 from 3-point range but held Washington State to 27 percent shooting (15-of-55).
Jerry McNair scored 21 points to lead Washington State (5-16, 0-13), which is one loss shy of the worst conference start in school history.
Thomas Kelati scored 13 points and Ezenwa Ukeagu grabbed 10 rebounds for the Cougars, who committed 21 turnovers and dished out only six assists.
