Lawrence, KS (SportsNetwork.com) - Perry Ellis had 15 points and five rebounds to help give No. 12 Kansas an 86-54 victory over Texas Tech on Saturday.

Kelly Oubre had 14 points, Cliff Alexander gave 12 points and five boards and Frank Mason had 10 points and five assists for the Jayhawks (13-2, 2-0 Big 12), who have won four straight.

"Everybody played well today," Kansas head coach Bill Self said. "We shot the ball fairly well, especially in the second half, and the starters were good, but I thought our bench was solid too."

Justin Jamison had 12 points for the Red Raiders (10-6, 0-3), who have dropped their first three games to open conference play.

Kansas led this game from start to finish, as the Jayhawks built an 11-2 lead after Wayne Selden put in a basket five minutes in.

An Alexander dunk gave the Jayhawks their first double-digit lead at 18-7 with 10 1/2 minutes left in the first half, and it was an 18-point lead with seven minutes left in the period on a pair of free throws from Mason that made the score 29-11.

Kansas eventually took a 42-25 lead into the break, then scored the first 11 points of the second half as Ellis hit a pair of threes, with the second making it a 53-25 game 3 1/2 minutes into the second half.

The Jayhawks led by as many as 38 the rest of the way.

"Their sheer physical size made it tough for us," Texas Tech head coach Tubby Smith said. "We have to compliment Kansas, they are a very talented team, the most talented team we have played so far."
