So much for Cal using the momentum of its upset of No. 1-ranked Arizona as fuel for the start of the second half of the Pac-12 basketball season.

A determined Stanford team evened the season series with Cal in an 80-69 victory Wednesday night at Haas Pavilion that left the rivals tied for third in the conference with 6-4 records. Stanford is 15-7 overall, Cal 15-8.

While the Cardinal was efficient and opportunistic, the Bears were careless and wasted a number of scoring opportunities close to the basket. All told Cal had 13 turnovers that Stanford converted into 21 points.

Dwight Powell led the Cardinal with 22 points and 11 rebounds and was supported by 19 points from Chasson Randle and 16 from Anthony Brown.

For Cal, Justin Cobbs was game-high with 24 points. Tyrone Wallace had 21 points and David Kravish 12.

Wallace’s three-point shot with 15:31 to go cut Stanford’s lead to five, 48-43, but five minutes later the Cardinal was back up by 10 after a free throw by Powell made it 57-47. Another Powell free throw pushed Stanford’s advantage to 60-47.

Stanford led at one point in the first half by 18 points when Randle sank a three-point shot for 38-20 before Cal realized it was in a game and had better start scoring.

The Bears then went on a 16-4 run to close out the half trailing by just six at 42-36 when Cobbs, the man with the hot hand, nailed a three-point shot as the buzzer sounded on intermission.

The Cardinal led for much of the half because it made 6 of 12 shots from three-point range and relied on its bench to outscore Cal’s reserves 8-2.

Kravish started out hot for Cal and scored his team’s first six points and had 10 by halftime. Cobbs by necessity had to step up his scoring opportunity and had 16 points by halftime.

For Stanford, Powell had 12 points and Randle 10.

Briefly: Cal’s football team attended the game en masse and sat behind the south basket, dressed in its home blue uniforms. … Former Cal wide receiver Keenan Allen, who had an outstanding rookie season with the San Diego Chargers, sat with his former teammates for the game.
