Norman, Okla. ? Kansas University junior Robby Price and sophomore Casey Lytle hit first-inning home runs and the Jayhawks’ bullpen pitched 3 1/3 innings of scoreless relief as Kansas defeated No. 9 Oklahoma, 5-4, Friday evening at L. Dale Mitchell Park.

The Jayhawks, now winners of five straight and eight of nine, improved to 32-15 overall and 11-8. OU fell to 33-13 overall and 11-8 in conference play.

In the top of the first, Price gave KU a 2-0 lead by slamming a 1-2 pitch over the right field wall following a lead-off walk to David Narodowski. The Jayhawks extended the lead after two outs, a Tony Thompson double and Lytle’s first career round-tripper.

The Jayhawks stretched the lead to 5-0 on a two-out RBI single by Preston Land, a ball that bounded up the middle with men on first and second in the third.

Kansas and OU face off again in a doubleheader at noon today.
