WEST LAFAYETTE, Ind. (AP) -- Katie Douglas scored 24 points to help Purdue overcome a 14-point first-half deficit and beat Vanderbilt 63-51 on Sunday.

Vanderbilt (1-1) grabbed a 23-9 lead during a 17-4 run early in the first half capped by Ashley Smith's 3-pointer with 11:42 left in the first 20 minutes.

But by halftime, Purdue (2-0) had cut the Commodores' lead to 37-31.

Douglas, who was 10 of 10 from the free throw line, ignited a 12-0 Purdue run during that allowed the Boilermakers (No. 19 ESPN/USA Today; No. 21 AP) to take a 46-41 lead with 10:33 to play.

Douglas, who scored 31 points, including the game-winning basket in the final second to lead Purdue past Dayton on Friday, scored the first six points in the run, hitting a 3-pointer and converting on a three-point play with 14:11 left.

Kelly Komara added 11 points for the Boilermakers, while reserve Shinika Parks had 10 points and seven rebounds.

Chavonne Hammond gave the Commodores their biggest lead of the second half at 41-34 with 16:50 left, but after her basket, Vanderbilt didn't score again until Cion Washington's jumper with 9:56 remaining.

Chanteelle Anderson scored with 9:03 remaining to trim Purdue's lead to 47-45, but Douglas scored the next four points to give Purdue a 51-45 lead.

Zuzana Klimesova led the Commodores with 13 points.

Purdue, the defending NCAA champion, has won 34 straight games.
