LUBBOCK, Texas -- An 11-run fifth inning aided No. 6 Oklahoma (28-5, 3-0 Big 12) as it completed a three-game sweep of Texas Tech (16-20, 0-3 Big 12) with a 21-6, five-inning win on Sunday afternoon.
The 21 runs were the second most OU has ever scored against a Big 12 team. The only higher run total was the 24 scored against Iowa State on April 26, 2013. Oklahoma has scored 20 or more runs three times this season. Prior to 2015, the team had only scored 20 or more runs five times in program history and never more than once in a season.
Oklahoma scored in 15 of 18 innings this weekend en route to outscoring the Red Raiders 43-12 in the three-game sweep. OU has won 10 consecutive meetings in the series, outscoring TTU 98-21 in that span. The team's 46-7 (.868) all-time mark in the series is its best winning percentage against another Big 12 team.
Four different OU hitters had at least two hits, led by Nicole Pendley going 4-for-4 with three RBIs to set a career high in hits. In addition to the 15 hits, Oklahoma drew eight walks and had five batters hit by a pitch.
Lauren Chamberlain hit a grand slam in the fifth inning, moving her into a tie for second place on the all-time home run list with Arizona's Stacie Chambers (2008-11) with 87 career home runs. It was Chamberlain's fifth career grand slam, and she is now three home runs away from tying the all-time mark of 90. Kady Self went 2-for-4 with a two-run homer and finished with four runs batted in. Erin Miller was 2-for-3 with two runs scored and two RBIs, while Kelsey Arnold added a three-run double in the first inning. Paige Parker got the win in relief to move to 13-3 on the season. She struck out five, walked one and gave up one hit while keeping the Red Raiders scoreless in the final 3.2 innings.
The Sooners used a patient approach at the plate to jump on Texas Tech starter Cara Custer in the first inning, scoring six runs while sending 10 batters to the plate.
Texas Tech got two of those six runs back in the bottom of the first thanks to a hit by pitch and walk in consecutive at-bats with the bases loaded. Oklahoma countered with three runs of its own in the top of the second. The Red Raiders cut the Sooners’ lead down to 9-6 after a four-run second inning. A fielding error by Texas Tech allowed another OU run to score in the third, while Parker quieted the Red Raiders' bats for the next two innings before Oklahoma tacked on the final 11 runs in the fifth.
The 11 runs in the fifth inning marked the third time this season that OU scored double-digits in an inning. All of three of those instances have come since March 14.
