BATON ROUGE, La. — Freshman DeMarcus Cousins had 19 points and 13 rebounds for his sixth consecutive double-double and No. 4 Kentucky cruised past LSU 81-55 on Saturday.

Cousins, who played only 20 minutes, is eighth in the country in doubles-doubles with 14 and 24th in the nation in rebounding.

The Wildcats (22-1, 7-1 Southeastern Conference) trailed 6-1 until John Wall hit a jumper 4:29 into the game. They needed only 3 minutes to erase LSU’s lead, scoring 41 of the next 49 points to take a 42-14 halftime lead.

Patrick Patterson had 16 points for Kentucky and Eric Bledsoe added 10. The Tigers limited Wall, the star freshman, to season-low six points on 2-of-9 shooting. It marked only the second time that Wall failed to reach double figures this season.

LSU (9-14, 0-9) shot less than 19 percent from the field in the first half and finished at 26.7 percent overall (21 of 66).

Bo Spencer led LSU with 25 points, 19 in the second half, but he had seven turnovers. Tasmin Mitchell added 10 points for the Tigers.
