Tyra Buss scored 16 points, leading a surge to open the fourth quarter and Indiana upended No. 24 Chattanooga 54-43 on Tuesday night in the preseason WNIT.
Amanda Cahill added 13 points for the Hoosiers (2-0), who will play DePaul in Chicago in the semifinals on Thursday.
Kym Royster scored the last basket of the third quarter to pull Indiana within 37-35 and scored the first two baskets of the fourth. Then Buss scored six straight points to put the Hoosiers ahead 45-37 before Keiana Gilbert's free throw ended the Mocs' drought at 4:49.
Gilbert led the Mocs (2-1) with 13 points and Chelsey Shumpert had 12.
Shumpert's jumper, followed by a 3-pointer at 3:38, cut the deficit to 47-43 but that was the end of the scoring for the Mocs.
Cahill hit a 3 with 2:47 left and Buss scored the last four points for Indiana.
