NORMAN, Okla. — Oklahoma softball knew it had a challenge ahead when reigning SEC Pitcher of the Year Karlyn Pickens rolled into town.

Pickens had a phenomenal outing in the circle over the last week for the Lady Volunteers. Pickens picked up three ranked wins over No. 14 Arkansas and No. 2 Oklahoma in addition to breaking the record for the fastest college softball pitch ever thrown, 78.2 mph, in the Lady Vol’s win over the Razorbacks.

With the loss, OU (31-3, 9-3 SEC) dropped its first series of the season. OU and Tennessee both finished with four hits apiece. Pickens tossed a complete game and following Sooners right fielder Kasidi Pickering’s three-run double retired six consecutive OU batters.
