OKLAHOMA CITY — Oklahoma used a six-run fourth inning to send Kansas University tumbling out of the Big 12 softball tournament.
Second-seeded OU (44-13), which had lost to KU on Thursday, handed the seventh-seeded Jayhawks (33-25) their first run-rule loss of the season, 10-0 in five innings, on Saturday at Hall of Fame Stadium.
"I give a lot of credit to Oklahoma," Kansas coach Tracy Bunge said. "They really came to play. They made some good adjustments and took advantage of us today. We were a little flat and not very energetic."
KU beat the Sooners, 3-1, on Thursday. Kansas was the first No. 7 seed to beat a No. 2 seed in tournament history.
But OU scored a run in the first, three in the third and six more in the fourth while keeping the Jayhawks scoreless despite four hits. The Sooners banged 14 hits, including three home runs, off three Kansas pitchers, including loser Kirsten Milhoan (6-7). Milhoan surrendered four runs all earned off nine hits over three innings.
Kami Keiter (12-6) earned the win after allowing three hits over four scoreless innings.
"I am pleased with our performance except for one inning in the previous three games," Bunge said. "I thought we played extremely well and represented the University of Kansas very well. We played to the best of our ability."
