Kubel allowed just two runs over eight innings and scattered eight hits while striking out three in the loss. The Sooners entered the game averaging eight runs per game.
As good as Kuebel was, Dillon Overton was better for the Sooners as he allowed no runs on seven hits and nine strikeouts in eight innings. He is now 3-0 on the season, while the Sooners improved to 7-0 this year.
Oklahoma scored its first run in the sixth and then tacked on a run each in the eighth and ninth innings. Iowa made things interesting in its half of the ninth inning with its only run but a strikeout by OU reliever Robert Tasin ended the threat and gave the Sooners the win.
Kris Goodman had three singles in the game and already has two three-hit games this year. He also extended his hit streak to four games, which matches a career-high.
Jake Yacinich also stretched his hit streak to four games as he went 2-for-3 from the dish.
