Omaha, Neb. ? Kansas University swept a day-night softball doubleheader Thursday, defeating Nebraska, 5-3, in Lincoln, and Creighton, 2-1, in Omaha.

The Jayhawks improved to 31-18-1 overall, 6-8 in Big 12 play.

Senior Kassie Humphreys figured in the decision in both Kansas victories and had a key two-run hit against the Cornhuskers to give the Jayhawks a four-game winning streak – all victories on the road.

In the afternoon game against Nebraska (34-16, 7-7), Humphreys tossed a three-hitter and helped her cause with a two-run single in a four-run sixth inning.

Sophomore Dougie McCaulley broke up Ashley DeBuhr’s no-hit bid to lead off the sixth with a single to left-center. Senior Nicole Washburn then reached on a fielder’s choice when the NU first baseman unsuccessfully attempted to cut off McCaulley at second.

Freshman Amanda Jobe walked to load the bases, and sophomore Stevie Cristoso knocked in the first Kansas run and reached on an error. Sophomore Elle Pottorf then hit a sacrifice fly to center field to put the Jayhawks ahead, 2-1, and set up Humphreys’ single. The Jayhawks added a run in the seventh when Washburn hit a two-out single to score sophomore Val Chapple from second after she had reached on a single to lead off the inning.

Humphreys struck out four while walking eight. The Huskers mounted a two-out rally, scoring three runs on three hits in the seventh, but fell short.

In the night game, the Jayhawks traveled to Omaha, where they defeated Creighton (32-11-1).

The Blue Jays scored first in the bottom half of the first inning, but Kansas scored twice to take back the lead. Cristoso led the inning off with a single and Pottorf followed suit. A sacrifice by freshman Sara Ramirez advanced the runners, and a Chapple single to right field scored Cristoso. Freshman Ally Stanton drove in the other run with a fielder’s choice.

Sophomore Valerie George started against Creighton, lasting 3 1/3 innings, until she was relieved by Humphreys after surrendering back-to-back singles. Although she walked a batter to load the bases, Humphreys escaped the jam by getting Creighton’s Michelle Koch to ground out to third base to end the inning. Humphreys raised her record to 17-10 .

The Jayhawks return to action Saturday, when they play host to Oklahoma. First pitch is 2 p.m. at Arrocha Ballpark.
