Around the Pac-10

With 12 wins, Washington State has already surpassed the win total of a year ago and matched the one from two seasons ago. Second-half comebacks have a lot to do with it. WSU is 5-1 after trailing at halftime. … No team came out of the first week of Pac-10 action more disappointed than Washington, which despite a lofty ranking and a big win over LSU in its recent past failed to win either game in Los Angeles. The Huskies tumbled 10 spots in the AP poll to No. 24, and they might need a win against Arizona this week to remain ranked. … Oregon is still undefeated, but the Ducks got their closest call in a three-point win against rival Oregon State last week. After a soft non-conference schedule, the Ducks’ first significant test will come this week at home against USC and UCLA. … Arizona has won 11 straight games and all five starters are averaging double figures.
