Idaho sophomore Stacey Barr led the Vandals with 21 points and 11 rebounds, and her jumper gave Idaho its late lead. Her 21 points were two shy of her career high, and it was her second double-double of the season.
"Stacey had been struggling the last few games, but she did a great job of attacking tonight and getting to the free throw line," Idaho coach Jon Newlee said. "She left everything out there tonight."
The Vandals fall to 12-14 overall and 9-6 in the Western Athletic Conference with the loss, their second straight, while LA Tech improves to 12-13 overall and 8-6 in WAC play.
"It's a disappointing way to lose," Newlee said. "We've got to defend better, rebound better and shot the ball better and not let it come down to that. I liked our resilience tonight, we came out with a lot of heart and desire in a tough environment."
Idaho's late one-point lead was its only second-half lead and its first lead since 5-4 with 18:00 to play in the first half.
Idaho senior Jessica Graham scored 13 points on 5-of-7 shooting and added seven rebounds. Freshman Ali Forde had seven points and six rebounds, and sophomore Krissy Karr finished with seven assists and three boards. Junior Alyssa Charlston, Idaho's leading scorer and rebounder this season, fouled out with five points and two rebounds, going 1-of-8 from the field in 19 minutes.
The Vandals shot 34.5 percent from the field, and matched their season-low with four 3-pointers, going 4-for-23 from long range. Idaho is now 0-10 on the season when shooting less than 35.0 percent from the field.
LA Tech shot 40.0 percent from the field in the game, and each team had 43 rebounds in the game. The Lady Techsters, however, out-scored Idaho 36-24 in the paint, 10-5 off turnovers and 10-6 on the second chance. Brittany Lewis led the Lady Techsters with 18 points, while Frazier finished with 17 points and nine boards.
Despite a tough night shooting, the Vandals stayed close at the free throw line, going 18-of-22 from the line while LA Tech got to the line just 15 times and converted only eight free throws.
The Vandals have 11 days off before their next game, when they host UTSA on Feb. 28. Idaho's final home game of the season is March 2 when Texas State visits the Cowan Spectrum, and the Vandals wrap up the regular season at Seattle U on March 9. The WAC tournament is March 12-16 in Las Vegas, Nev.
