Wecker, who joined former Wildcat Nicole Ohlde in the 2,000-point club with her 10th point of the game at the 15:49 mark of the second half, scored 13 of her game-high 19 points in the after intermission, including K-State's final seven points and the game winner with just 7.4 seconds to play, to give Kansas State (14-3, 5-1) its first win over the Lady Raiders in Lubbock since 1978.
Texas Tech (15-2, 5-1), which saw its eight-game winning streak end, had a chance to force overtime, but Erin Grant was unable to knock down an open look in the lane as time wound down.
LaToya Davis scored 16 points to pace the Lady Raiders, who scored on just three of their final 11 possessions and were held to just 36 percent shooting in their first conference loss in six games.
Kansas State trailed by as many as seven points with 13 minutes to play in the first half. But the Wildcats set the tone for the second half with a 7-3 burst over the final six minutes to slice the game to 27-26 at the break.
Six ties and 13 lead changes would ensue over the final 20 minutes, the last coming when Wecker hit a jumper to give K-State a 50-49 lead it would never relinquish.
Kansas State will look to make it six wins in a row on Tuesday, Jan. 25, when the Wildcats return to Bramlage Coliseum to take on Iowa State at 7 p.m.
