LSU, which allowed No. 25 Florida to make a school-record 19 3-pointers in the Gators' 106-71 victory Wednesday night, saw Texas Tech make three 3-pointers in jumping to an 11-2 lead before the Tigers switched from a zone to man-to-man defense.

After the switch, the Red Raiders made three more 3-pointers and led 20-12. Texas Tech increased its lead to 30-19 after making 8 of 12 3-pointers.

Reath, Blakeney and Sims combined to score all of LSU's points as it climbed within nine before Stevenson made the Red Raiders' 10th 3-pointer (on 15 attempts) to give them a 39-27 halftime lead.
