Fourth-seeded Oklahoma (50-8) routed 13th-seeded Arizona (38-19) to get to the Women's College World Series for the second consecutive season, leaving Arizona home in June for just the third time in the last 25 years.
The Sooners plated five runs in the first inning and cruised to a 7-1 win in game two of the NCAA Super Regional.
Arizona fell short of the 40-win mark for just the first time since 1986 with the loss.
Kenzie Fowler allowed seven runs on nine hits while walking five, hitting one and striking out two in five and a third innings of work. Fowler allowed the first six batters she faced to reach and issued a pair of RBI free passes in the first inning. Fowler finished the season 15-9 on the season. Shelby Babcock relieved Fowler with one out in the sixth inning and retired five of the six batters she faced.
OU starter Keilani Ricketts did not allow an earned run in her three-hit, 13-strikeout complete game. At one point, Ricketts struck out nine straight Wildcats from the third to the fifth inning. Ricketts improved to 33-7 on the season.
The Sooners got their first six on board and scored five runs on just two hits in the first inning. The inning included an RBI walk, RBI HBP and a two-run error.
Fowler was able to hold OU off the scoreboard until the fifth when Jessica Shults led off the frame with a homer to give the Sooners a 6-0 lead.
Another solo home run, this by Lauren Chamberlain, put the Sooners up by seven runs and gave Arizona its largest deficit of the season.
Arizona's first run of the super regional came in the sixth inning when a single and walk put two on for Koria with two out. The senior's groundball was booted by OU third baseman Javen Henson, allowing Buchanan to score from second. The Wildcats later loaded the bases with two out, their biggest threat against Ricketts in the weekend, but could not score.
UA got a runner to third in the seventh, but Buchanan's groundout ended the season for Arizona.
The Wildcats finished the season 38-19. The 19 losses match the most since losing 24 in 1983. The 2008 and 1989 clubs also dropped 19 games.
