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.

OU dropped its series finale against No. 10 Tennessee on Sunday, 5-3, and dropped a Southeastern Conference series for the first time in school history. The Sooners had beaten South Carolina, Arkansas and Missouri in its first three SEC sets.
