TEMPE, Ariz. -- Arizona State buried Idaho State with a school-record avalanche of 3-pointers.
The Sun Devils (No. 17 ESPN/USA Today, No. 20 AP) won 90-55 Tuesday in a rout so complete coach Herb Sendek could find nothing to criticize.
"You hope at some point synergy -- kind of a fun word -- takes over and the whole does become greater than the sum of its parts, and guys do make each other better, feed off each other and help each other," Sendek said. "That's the way the game's meant to be played."
James Harden, who made 3-of-6 3s, scored 18 points in just 26 minutes as Arizona State improved to 10-1, matching its best start in 34 seasons. All five Arizona State starters hit double figures.
The Sun Devils, who entered the game first among Pac-10 schools with 8.4 3-pointers a game, made 17-for-32.
"I've been coaching 30 years," Idaho State coach Joe O'Brien said, "and I don't know that I've been involved in a game where the opponent shot the ball that well that long. ... They shot the ball well from start to finish, everybody that played."
"We finished with 25 assists on 28 baskets, which is somewhat remarkable," Sendek said.
Harden said Sendek had preached shot preparation all week.
"You know, being ready to shoot when the ball's there, having your feet under you, just the whole nine yards," Harden said, "and today we did that."
Derek Glasser had 11 points and matched his career best with nine assists for Arizona State.
The blowout followed two tense victories for the Sun Devils, 59-58 in overtime over IUPUI and 76-75 over previously unbeaten BYU.
Idaho State beat Utah, lost three games in overtime and was defeated at Wisconsin on a last-second shot, but this won't join that list of near misses.
"I don't think today is an indication of how good a basketball team we are or how bad a basketball team we are," O'Brien said. "It was just a day we need to put behind us. We weren't very good and they were very, very good."
The Sun Devils made 10-of-17 3-pointers to take a 43-28 halftime lead.
Arizona State's last six field goals of the half were 3s, three by Harden.
His string of three 3-pointers capped an 18-9 run that put Arizona State ahead 35-23 with 4:36 left in the half. Abbott's third 3 of the game, 38 seconds before the break, gave the Sun Devils their 15-point halftime cushion.
The rout was on after that. The Sun Devils outscored the Bengals 27-4 to start the second half, taking a 70-32 lead with 11:25 to play. The school 3-point record fell when Jerren Shipp made one from the corner with 2:50 to play.
Arizona State has one nonconference game left, against Central Connecticut State on Monday night, before opening Pac-10 play next Friday at Stanford.
