No. 10 Oklahoma (45-10, 16-2) closed the regular season Sunday with an 11-3, five-inning win over Oklahoma State (26-28, 5-13) on Senior Day in front of a Marita Hynes Field record crowd of 1,728.
Senior Brittany Williams was a career best 4-for-4 at the plate and drove in a career-high six runs. She hit a three-run home run in the first inning and added run-scoring singles in the second and fourth innings. Williams capped her career day with the game-winning single in the fifth inning.
The home run was Williams' 10th of the season and the 35th of her career. She's tied with teammate Shelby Pendley for 10th most in a career in OU history. Pendley also drove in a pair of runs Sunday with a two-run double in the second. She finished 3-4 with two runs scored.
Oklahoma State cut a seven-run lead to 7-2 in the third on Ari Morrison's home run, her second of the season and the fifth of her career, over the fence in rightfield. The Cowgirls made the score 7-3 in the fourth when DeLaCruz's fly ball down the leftfield line just made it over the wall at the foul pole and over the outstretched glove of OU's Paris Townsend. It was the shortstop's fifth homer of the season and the eighth of her career.
OU sophomore Erin Miller entered the game as a defensive replacement in the fourth and ended up with a two-run homer in the fifth inning. It was her third home run of the season.
Oklahoma finished the regular season on a 12-game winning streak and as winners of 27 of its past 29 games.
OU finished Big 12 play with a 16-2 record. That matches the 2008 season for the best Big 12 winning percentage in program history.
The Cowgirls finished the season with a 26-28 overall record, including 5-13 in Big 12 play. Of OSU's 28 losses this season, 14 were to ranked opponents, and 13 were by one run.
The Sooners will find out their postseason assignment Sunday night with the NCAA Selection Show at 9 p.m. CT on ESPNU.
