Oklahoma softball knew it had a challenge ahead when reigning SEC Pitcher of the Year Karlyn Pickens rolled into town. In last week’s Lady Vols' win over Arkansas, Pickens set the record for fastest-recorded pitch in softball history when she was clocked at 78.

The second-ranked OU softball team suffered its first series loss as a member of the SEC with a 5-3 loss to Tennessee on Sunday afternoon at Love’s Field.
