Gasso offered Casey a scholarship, and she quickly accepted.
There was, of course, homesickness and major adjustments to life an ocean away from home.
“She's handled it so maturely,” Gasso said. “I've been really impressed with her, but also with my other athletes who have taken her in and made her feel welcome.”
In December, Casey was playing in a tournament back home and tore ligaments in her ankle, which cost her the first six weeks of her freshman season.
She made her debut as a pinch hitter March 2 against LSU, started her first game the next day against Iowa and has been in Gasso's lineup ever since.
“When she came back, our world changed,” Gasso said. “Georgia really changed the dynamic of our team when she came back on board.”
Just before last weekend's regional, Gasso made Casey the Sooners' leadoff hitter, and she's flourished in the role.
“It's a different kind of position than the 4, 5 and 6 (spots in the lineup),” Casey said. “In the leadoff role, your job is to get on base and put off a positive start to the game. You just have to look at it differently and have different goals.”
With Keilani Ricketts (31-7) and Michelle Gascoigne (16-1), Oklahoma has pitching covered this season.
But this summer, Gasso said she expects Casey to work from the circle and get used to pitching again.
“Just whatever the team needs,” Casey said. “I'm sure in the future I'll see more pitching time. I've always done both, but right now, our pitching is taken care of.”
After committing to Oklahoma last year, Casey watched online from Australia as the Sooners competed in the Women's College World Series. She's never played before a crowd quite like that, but is excited for the opportunity.
Gasso, who said this experience will make her think about bringing in more international recruits, is just happy to have Casey on board.
“Man, she has just exceeded any and every expectation I had at the plate and on the field, and I haven't even used her on the mound yet,” Gasso said. “She's a sponge; she wants to learn so much. She's probably the most advanced and knowledgeable freshman that I've ever had in this program, by far.”
