Liv McGill scored 34 points and No. 19 Oklahoma State pulled away in the third quarter to defeat South Dakota State 90-80 on Sunday.
The win marked the first time the Cowgirls have defeated the Jackrabbits in three meetings, according to Yahoo Sports.
McGill recorded her fifth career 30-point game, trailing only the 38 points she scored against Chattanooga while playing for Florida last season.
In addition to her scoring output, McGill contributed seven assists and four rebounds to the Oklahoma State effort.
Teammates Audi Crooks and Yuting Deng added 18 and 15 points, respectively, while Callin Hake chipped in 10 points for the Cowgirls, who improved to 4-1 on the season.
South Dakota State, which fell to 1-3, saw identical 18-point performances from Brooklyn Meyer and Hadley Thul.
Claire Sheppard added 15 points for the Jackrabbits, with Emilee Fox scoring 12 and Audrey Shindelar contributing 11.
The contest remained competitive early, with neither team leading by more than four points until Oklahoma State went on a 13-0 run.
That surge gave the Cowgirls a 32-21 lead with roughly five minutes remaining in the first half.
However, the Jackrabbits responded by making eight of their next 10 field goal attempts to tie the game at 42 by halftime.
The game turned decisively in the third quarter, as Oklahoma State outscored South Dakota State 34-18 to build a 76-60 advantage heading into the final frame.
Although the Jackrabbits cut their deficit to nine points twice in the fourth quarter, they were unable to overcome the gap.
The Cowgirls are scheduled to face St. John’s on Wednesday, the Associated Press reported.
South Dakota State will also return to action on Wednesday against Wyoming.
