NORMAN, Okla. -- Haley Lee hit a grand slam, Cydney Sanders and Alyssa Brito each added a homer and top-ranked Oklahoma extended its winning streak to 47 with a 9-2 victory over Clemson in the opener of the Norman Super Regional on Friday.
Oklahoma (55-1) tied Arizona's all-time Division I record of 47 straight wins -- set in 1997. The Sooners seek to break the record Saturday in Game 2 of the best-of-three series with Clemson (49-11).
Oklahoma had two fielding errors in the fifth inning as Clemson pulled within 4-2, but the Sooners broke it open in the bottom half with five straight hits, including a grand slam.
Oklahoma's 15th error of the season put runners on second and third with one out in the fifth. Caroline Jacobsen took advantage by hitting a two-run double down the line. Clemson loaded the bases after Oklahoma's second error of the inning, but Jordy Bahl ended the threat with a strikeout and a soft liner to Tiare Jennings at second base.
Oklahoma's first three batters of the fifth inning reached on hits -- after just four pitches -- and then Lee cleared the bases for an 8-2 lead. After a pitching change, Brito hit her 16th home run of the season.
Sanders hit her two-run homer in the fourth to extend Oklahoma's lead to 4-0. It was her third straight NCAA tournament game with a home run.
