NaLyssa Smith had her eighth consecutive double-double with 25 points and 17 rebounds, and fifth-ranked Baylor handed Missouri its first loss of the season, 70-68, in the Big 12/SEC Challenge on Saturday night.

"That first half for us was probably one of the rougher halves of basketball we’ve had so far this season," Missouri coach Robin Pingeton said. "I thought we were able to regroup, recalibrate and really came out and battled in that second half."

Missouri, which trailed by nine at halftime, took its only lead of the game with 7:11 left — 60-57 on Haley Troup's 3-pointer. The Tigers then didn't score for nearly five minutes, while Baylor (8-1) got 12 points in a row to go back ahead to stay, though Lauren Hansen's 3-pointer pulled Mizzou within one with 34 seconds left.

"I’m proud of the grit of our team, I’m proud of the resiliency," Pingeton said. "But this is a hard one when you’re right there."

Aijha Blackwell, who was a USA Basketball teammate with Smith, had 20 points and 16 rebounds for Missouri (8-1) before fouling out with 3:56 left. Troup finished with 16 points and Hansen had 10. Hansen missed a 3-pointer with 20 seconds left and a potential game-tying jumper as time expired.

The Bears hadn’t played Missouri since the Tigers left the Big 12 for the SEC after the 2011-12 season.

Smith, the preseason AP All-American, scored half of Baylor's points in the game-clinching 12-0 run.

"I feel like we feed off of just seeing each other make the baskets, see the ball go in," Smith said. "Anytime that we do score it’s like high energy."

Smith had a go-ahead three-point play with 6:12 left, when she was fouled when making a putback short jumper and added the free throw to make it 61-60.

"NaLyssa is just such a powerful player and is surrounded by some tremendous players," Pingeton said.

Caitlin Bickle added 11 points for Baylor and Sarah Andrews 10.
