The Cowgirls have ended 13 games this season in less than seven innings (all wins), but their series finale on Sunday lasted nearly four hours.
Oklahoma State secured another weekend series win but saw a seven-game win streak end in extra innings and was handed its first conference loss.
The Cowgirls came into the weekend ranked No. 3 with a 37-3 record (6-0 in the Big 12) while the Cyclones were just 13-23 and 1-8 in conference. But the Cyclones made things tough on the home team all weekend and came out on top in 11 innings on Sunday.
