STANFORD, Calif. (AP) - Brenna Chase had 19 points, seven assists and three blocked shots, and seventh-seeded BYU used an impressive third quarter to run away from No. 10 seed Auburn 73-64 in the first round of the NCAA Tournament on Saturday.
Shaylee Gonzales scored 17 points and Caitlyn Alldredge added 14 as the West Coast Conference champion Cougars (26-6) overcame Auburn's in-your-face, pressure-at-every-chance defense by playing its own stellar D - getting four blocks from 6-foot-7 Sara Hamson.
BYU will play Monday against the winner of Saturday's second game between No. 2 seed and host Stanford (28-4) and Big West champion and 15th-seeded UC Davis (25-6).
The Cougars hit 7 of their first 10 shots out of halftime and used an 11-0 run in the third to take control, while Auburn continued to struggle shooting and missed eight in a row during a costly stretch.
Auburn senior and leading scorer Janiah McKay had 19 points going 6 for 18 from the floor for cold-shooting Auburn (22-10) in her final college game.
This wasn't how McKay wanted to finish her career. All season she was determined to get back to the big March stage after last season's miss, and this was the Tigers' third NCAA berth in four years.
McKay got her team on the board with an early 3 then her team struggled until she scored with a driving layup at the 3:40 mark after Auburn went more than 2 minutes without a basket.
BYU had its own scoring struggles until getting on track after the break.
Auburn jumped into the passing lanes, crashed the offensive boards to create extra chances and hit the floor for loose balls in outhustling BYU in the opening quarter. The Tigers stayed close because of their defense when the shots didn't fall, getting 14 steals for the game.
It was another balanced performance by the Cougars, who have multiple 3-point threats as well as Hamson in the middle. BYU got back to the tournament for the first time since 2016 and a first-round loss to Missouri.
BYU pulled off an 82-68 upset of favored-but-injury-plagued Gonzaga in the WCC tournament championship game. The Cougars are back in the NCAA Tournament for the first time since 2016.
Both teams came out cold from the floor, 2 of 7 by BYU and Auburn's 2 for 12.
