The Jayhawks are 0-4 in league games and 16-15 overall. The Cowgirls are 27-12 and have won two of five Big 12 contests. OSU received 11 votes in this week’s ESPN.com/USA poll.

Kansas is expected to have freshman catcher Elle Pottorf back for the OSU series. Pottorf suffered a leg bruise last weekend against Texas A&M and missed Tuesday’s 8-0 victory over UMKC.

“She’s much better,” KU coach Tracy Bunge said of Pottorf, the Jayhawks’ third-leading hitter with a .286 average. “We’re hoping Elle can go. She’s probable.”

Junior Serena Settlemier has emerged as the Jayhawks’ top pitcher with eight wins in 13 decisions and will start today’s game. Freshman lefty Christina Ross (5-5) has pitched 601/3 innings and has a team-best 1.97 earned-run average to go with 55 strikeouts, but sophomore right-hander Kassie Humphreys’ ERA has ballooned to above 4.00.
