LAWRENCE, Kan. — No. 8 Kansas has turned its attention squarely to fourth-ranked Missouri and one of the biggest meetings between the two border rivals in years.

The Jayhawks (18-4, 8-1 Big 12) took care of business against Oklahoma on Wednesday night. First place will be on the line when they meet Missouri in Columbia, Mo., on Saturday night.

Missouri (20-2, 7-2) is just a game back in the standings. It'll be the first time since 2009 that the teams have met with the Big 12 lead up for grabs.

Kansas has won the last five overall against the Tigers.
