Sioux Falls, s.d. — Alexis Peterson scored a season-high 29 points, Brianna Butler hit three straight 3-pointers early in the fourth quarter to break open the game, and Syracuse advanced to its first women’s Final Four with an 89-67 victory over Tennessee in the Sioux Falls Regional final Sunday.

The fourth-seeded Orange (29-7) will play No. 7 seed Washington in a national semifinal next Sunday in Indianapolis.

Reserve Cornelia Fondren made all six of her shots and finished with 13 points to help Syracuse follow its Friday upset of top-seeded South Carolina with its 15th victory in 16 games.

Diamond DeShields scored 20 points and had 10 rebounds to lead the Lady Vols (22-14) in the loss that finished their surprise NCAA run after a 13-loss regular season that was the worst in program history.

Peterson, who had a season-high 26 points against the Gamecocks, has scored 20 or more in each of the Orange’s four tournament games. She collapsed at midcourt in tears of joy after the final buzzer as teammates swarmed her, and she flashed a No. 1 with her right finger as she embraced Brittney Sykes.

Butler, the NCAA active leader in career field goals, made six 3-pointers for the third time this season and scored 18 points.

Butler’s back-to-back 3-pointers gave the Orange a double-digit lead after the Lady Vols pulled to 63-59 early in the fourth quarter. Syracuse was up 12 after Peterson’s jumper that followed DeShields’ offensive foul, and the bulge eventually grew to 23.

Syracuse was able to attack Tennessee’s 2-3 zone however it pleased. With Butler’s 3-point touch always a threat, Peterson once and Fondren twice sliced through for layups on three straight possessions in the third quarter, and Peterson hit a jumper from the corner on the next for a 51-41 lead.

DeShields kept the Lady Vols in range, at least temporarily, scoring 11 points the first 6:42 of the third quarter and forcing Syracuse to call a timeout after hitting two straight 3s to pull her team to 54-51. Maggie Morrison’s 3-pointer and another snaking layup by Fondren pushed Syracuse’s lead back to 63-53.

Jaime Nared added 11 points for Tennessee, which committed 21 turnovers against the Orange’s pressure 2-3 zone defense. The Orange converted those turnovers in 17 points.

Mercedes Russell, who had a career-high 25 points against Ohio State on Friday and came into the game shooting 70 percent in her first three tournament games, was limited to just five shots and finished with seven points. The Lady Vols’ other post, Bashaara Graves, was 3 for 8 for 11 points.

Tennessee was trying to reach its 19th Final Four and first under fourth-year coach Holly Warlick. The Lady Vols haven’t made it to the national semifinals since 2008, the year they won their last of eight championships.

The Lady Vols were without starting guard Jordan Reynolds, who was out after getting hit in the face against South Carolina. Te’a Cooper made her first start since Feb. 25 and had eight points after coming off the bench to score 16 against Ohio State.

Washington 85, Stanford 76

Lexington, Ky. — Kelsey Plum scored 26 points and Chantel Osahor had 24 points and 18 rebounds Sunday as Washington defeated Stanford 85-76 in the NCAA Lexington Regional final to earn its first women’s basketball Final Four appearance.

The seventh-seeded Huskies scored the game’s first 12 points and stayed ahead the rest of the way. Washington (26-10) will play either Syracuse or Tennessee in an NCAA semifinal April 3 in Indianapolis.

Stanford, the No. 4 seed, was seeking its 13th Final Four appearance overall, and seventh in the last nine years.

Lili Thompson scored 19 points for Stanford (27-8). Erica McCall added 17 points — all in the second half –and 15 rebounds.

This marked the first regional final between two Pac-12 schools since Stanford beat Southern California 82-62 on its way to winning the national championship in 1992, when the conference was still known as the Pac-10.

Osahor, who had shot a combined 3 of 13 and had averaged just 4.5 points in Washington’s two previous games with Stanford, was a model of efficiency Sunday.

She shot 8 of 11 from the floor to match her career high in scoring. Osahor’s physical presence early in the game also helped Washington stifle McCall, who went scoreless in the first half Sunday after scoring a career-high 27 points against Notre Dame.

Thompson shot 5 of 10 and scored 13 points in the first half, but her Stanford teammates were a combined 5 of 24 for 13 points.

The Cardinal shot much better in the second half and cut Washington’s lead to 67-63 with 7:19 left after Karlie Samuelson, Thompson, Marta Sniezek and McCall hit 3-pointers on consecutive possessions.

Stanford had the ball with a chance to cut further into the lead when Plum made a steal and drove to the basket. Although Plum missed her layup, Talia Walton delivered a putback that made it 69-63 with 6:23 remaining.

The Cardinal made one more charge in the closing minutes, but Washington wouldn’t fold.

Walton had 12 points and Alexus Atchley added 11 for Washington. Samuelson scored 12 points and Sniezek added 10 points and six assists for Stanford, who shot 14 of 33 from 3-point range.
