Brigitte Ardossi had 18 points and Alex Montgomery scored 17 off the bench to lead the Yellow Jackets to a 70-48 victory over Arizona on Sunday.
It was Georgia Tech's second victory over a Pac-10 team in five days. The Yellow Jackets defeated Oregon 87-69 on Wednesday.
"Teams better not come here to the South and expect a win," said Montgomery, a junior from Tacoma, Wash. "Since I'm from the West Coast, it was extra motivation for me. I came to Georgia Tech for a reason."
Montgomery, who is still rounding into shape after knee surgery, had 13 of her points in the first half, going 3-for-3 on 3-pointers and 4-for-4 from the foul line. She also had a team-best eight rebounds.
Georgia Tech (9-2) shot 52.8 percent (28-for-53), including 5-for-11 from behind the arc.
Ardossi, a senior from Australia, was 8 of 10 from the floor after making all nine of her shots against Oregon.
"I'm just trying to be consistent," Ardossi said. "This is the most talented team I've played on. We are capable of beating any team we play."
Soana Lucet, who had 10 of Arizona's first 12 points, finished with 19 to lead the Wildcats (5-3) and Ify Ibekwe had 11 rebounds. Arizona was just 2 of 21 on 3-pointers and shot 35 percent overall (21-for-60).
"We could never get anything going offensively," said Arizona coach Niya Butts, who is from Americus, Ga., and had more than 100 family members and friends in attendance.
Arizona scored the first six points and led 17-10. But Montgomery's 3-pointer put Georgia Tech ahead for good at 24-22 and a 21-5 run put the Yellow Jackets up 41-27 at halftime.
"We went to a half-court trap and a zone," Georgia Tech coach MaChelle Joseph said. "They struggled when we made that adjustment."
Georgia Tech concludes a stretch of five games in 10 days at Georgia State on Tuesday. Georgia State is 9-1, with the only loss to No. 10 Florida State.
The ACC opener for the Yellow Jackets is Jan. 6 at preseason favorite North Carolina, ranked No. 9.
"We're one of the few teams that has played every power conference," Joseph said. "Playing these top teams has really prepared us for what's around the corner, the ACC. We feel like we've seen a little bit of everything."
