WACO, Texas (AP) -- Chameka Scott wasn't in the Baylor starting lineup for the first time this season. Instead, she was playing and making shots when they were needed the most.
Scott made sure the Lady Bears avoided consecutive losses, hitting three 3-pointers in the late deciding run that pushed Baylor (No. 3 ESPN/USA Today, No. 2 AP) to a 78-68 win over Oklahoma on Sunday.
"I just wanted to contribute," Scott said. "Starting is just a mindset, finishing is a much bigger deal. ... I want to be that player that gets us out of tough situations."
The Lady Bears (13-2, 3-1 Big 12), the nation's best 3-point shooting team, had made just one long-range shot before Scott hit from the left wing with 8:49 left for a 53-52 lead. That also started a 16-4 run.
By the time Scott made her third 3-pointer with just over five minutes left, Baylor led 66-56. Freshman Angela Tisdale also had a 3-pointer in the stretch.
"Two of Scott's 3s were as highly contested as they can be without blocking the shot," Oklahoma coach Sherri Coale said. "They were just big-time plays."
Looking for a better defensive lineup after a 103-99 loss in triple overtime at Nebraska on Wednesday night, Baylor coach Kim Mulkey-Robertson made changes.
Scott sat to start the game. She still played 29 minutes and scored 11 points to be one of five players in double figures for Baylor, which won its 11th straight home game.
Emily Neimann had 16 points while Steffanie Blackmon and Abiola Wabara -- who started instead of Scott -- both had 14. Sophia Young had 11.
Leah Rush had 26 points to lead Oklahoma in scoring for the fourth game. Lauren Shoush had 11 points and Dionnah Jackson had eight points on 3-of-15 shooting with eight rebounds.
Oklahoma (9-5, 1-2) accomplished its primary defensive goal by limiting Blackmon and Young, post players averaging 17 points each. But Scott and Tisdale, whose only points came on three 3-pointers, became unexpected heroes.
"We felt like Option A for Baylor is go to their bigs in the lane," Coale said. "So we try to make them go to Option B, maybe make them go to Option C. I felt like we did that. Option C for them was really, really good."
The Lady Bears, who came in shooting 43 percent on 3-pointers, made just 1-of-5 before halftime and missed their only other second-half attempt before Scott and Tisdale starting making them.
"I told them at halftime, Chameka in particular, those shots have to be nailed," Mulkey-Robertson said. "Chameka and Angela grew up tonight in pressure situations. They nailed some big buckets."
Oklahoma, which had won 11 straight in the series before being swept in two games last season, twice cut the lead to three in the final two minutes. Tisdale responded with 3-pointers both times.
Between Baylor's quick start and impressive finish, the game was tied 11 times and there were 14 lead changes.
Rush started 1-of-5 but finished 12-of-21 shooting. Her consecutive baskets, a putback and a short baseline jumper, gave Oklahoma its largest lead, 26-22 with 4:43 left in the first half.
Less than a minute later, Baylor was back in front when Chelsea Whitaker drove and flipped the ball up with her left hand while falling away from the basket. The ball went in, she was fouled by Rush and then made the free throw for a 27-26 lead.
Baylor is 67-10 at home in five seasons under Mulkey-Robertson. Before the Nebraska loss, the Lady Bears had won 12 straight since a 71-70 loss to LSU in the season opener.
