NORMAN, Okla. – Despite dropping the doubles point, No. 9 Baylor’s singles lineup carried the Lady Bears to a 5-2 win against 19th-ranked Oklahoma. Sunday's victory was the seventh in a row against the Sooners.

The win moves Baylor to 14-3 overall and 4-1 in the Big 12, while dropping Oklahoma to 12-3 overall and handing the Sooners their first loss within the Big 12 (4-1).

Oklahoma came out and took over on the first two doubles courts. Ana-Maria Constantinescu and Alice Radu gave up just one game to Baylor’s Karolina Filipiak and Nina Secerbegovic at the No. 1 doubles spot, defeating the Bears’ duo, 8-1. On Court 2 Mia Lancaster and Whitney Ritchie won their seventh-straight doubles match as a pair to remain undefeated in doubles play by beating Baylor’s Sona Novakova and Diana Nakic.

“Doubles was very outstanding and I felt going into the match that we were the better doubles team,” OU head coach David Mullins said. “I wasn’t surprised that we won the doubles point but I was surprised at how quickly we won and how decisive it was.”

But Baylor fought back with a win on the final doubles court, before taking the first four singles courts to earn the victory.

With the move indoors due to inclement weather, only three singles courts could be played at once, and Baylor went 3-0 on the first three courts. No. 19 Novakova took on Oklahoma’s lone ranked player, No. 95 Constantinescu, and had no troubles on her way to a 6-4, 6-0 win.

44th-ranked Nakic won by just a break in the first set 7-5, then found her stroke in a 6-1 second-set win to give Baylor a 2-1 lead.

Meanwhile, No. 34 Secerbegovic took an 11-match singles win streak into the day against Radu on Court 2. Secerbegovic took the first set 6-2, but lost the second 4-6 before rebounding for a 6-2 third set victory. The second-set loss was the first time in seven matches that she had lost a set.

With a 3-1 lead, Baylor needed just one more point to clinch the win, and got it from Jelena Stanivuk on Court 4. The senior, ranked 119th, won in straight sets, 6-2, 7-5, over Marie-Pier Huet.

"We're starting to grow as a team and it showed today," Baylor head coach Joey Scrivano said. "I like the way we are maturing, however there are always things that we can do better. We'll have to address those areas before we play Florida in couple of days."

No. 116 Filipiak added a super tiebreaker win on Court 5 against Lancaster, battling back from down a set. Filipiak lost the first 3-6, but won the second 6-2 and took the super tiebreaker 10-6. The loss, only Lancaster's second of the season, snapped her nine-match winning streak.

On the final court, Baylor's Taylor Ormond was up a set (6-2) and down 2-1 in the second versus Maria Kalashnikova, but she retired to keep from injury after missing the majority of the season.

“In singles, they were just better,” Mullins said. “I really can’t fault our players at all, give all the credit to Baylor they were definitely the better singles team from top to bottom.”

Baylor’s lone win in doubles on Court 3 came after the team point was decided. Stanivuk and Ormond held on for an 8-6 win over Huet and Tara Eckel.
