Basketball: Sunday wrap

There will be a lot of mismatches like this one early in the season: Arizona 90, Idaho State 42. At halftime, the Wildcats led 41-15. Ouch.

Sophomore forward Derrick Williams shot 6-for-7 from the field and scored 16 points in just 20 minutes, one of four UA players to reach double digits in the Cats’ season opener.  Arizona shot nearly 60 percent and held the Bengals to 28 percent, including 1 for 12 from 3-point range.

Elsewhere in the Pac-10:

— Oregon State: The Beavers got 15 points from forward Omari Johnson and 14 from 5-foot-8 freshman guard Ahmad Starks in a 71-56 season-opening win over visiting Texas-Arlington. Perimeter shooting was a sore spot for OSU last season and an 8-for-28 performance from 3-point range suggests the issue may not be resolved.

— Oregon: Senior forward Joevan Catron scored the Ducks’ final five points, sealing a 72-70 victory over UC Santa Barbara. Catron finished with 15 points and PF Malcolm Armstead contributed 12 points and seven assists as Oregon improved to 3-0 under first-year coach Dana Altman.

STEPH’S KID BROTHER: Seth Curry, younger sibling of Warriors’ second-year star Stephen Curry and a transfer from Liberty University, had 16 points in his Duke debut, helping the defending national champs to a 97-60 win over Princeton.

FRESHMAN REPORT: A nice debut by Duke freshman point guard Kyrie Irving, who had 17 points and nine assists vs. Princeton. Rivals.com rated Irving as the nation’s No. 2 PG prospect a year ago.
