STANFORD, Calif. -- KZ Okpala matched his career high with 29 points but it wasn't enough as Stanford fell 75-70 to Arizona on Wednesday night at Maples Pavilion.
Brandon Randolph scored a team-high 17 points for Arizona, which had five players score in double figures. The Wildcats (12-4, 3-0 Pac-12) have now won 18 straight in the series, with the Cardinal's last victory coming back on Jan. 4, 2009.
Stanford (7-8, 0-3 Pac-12) moved in front 50-44 with 12:42 remaining in the second period before Arizona scored 13 of the next 15 points to take control.
The Cardinal crept to within one point five times in the final four minutes, including at the 1:13 mark when Josh Sharma dunked following an alley-oop pass from Okpala to trail 69-68. Ira Lee then scored four consecutive points, extending Arizona's lead to 73-68.
Okpala finished 11-16 from the field and 7-12 from the charity stripe. Okpala fell one point short of joining Landry Fields (31 points on Jan. 28. 2010) as being the only Cardinal players to score at least 30 against Arizona since 1996.
Daejon Davis added 15 points while Josh Sharma grabbed a team-high seven rebounds to go along with eight points. Four players grabbed at least six rebounds as Stanford held a 35-31 advantage on the glass.
The Cardinal shot 54.0 percent compared to the Wildcats' 41.3 percent clip. However, Stanford was just 1-8 from three-point range, 15-26 from the foul line and was victimized by 19 turnovers.
Arizona made an early run to go up by eight less than four minutes into the contest but the Cardinal was able to rally and take a 24-23 lead with 6:31 left in the first half.
The Wildcats regained the lead 13 seconds later and stayed in front the rest of the first half, taking a 40-38 advantage into the intermission.
Stanford returns home Saturday to host Arizona State at 3 p.m. at Maples Pavilion.
