O'Leary finished her season with a 0.39 earned-run average, struck out 237 and walked 27. She started all but three games for the Spartans and had a win-loss record of 25-2 with 23 complete games and 16 shutouts. The ace also held batters to a .137 batting average and .187 on-base percentage.
"[O'Leary] has the movement and she relies on that," Cervenka said. "When you have that you don't have to throw hard … if you're keeping the batters off-balance you're doing your job. She's very, very tough and that's come with years and made her the pitcher that she is."
As far as style goes, Cervenka labels O'Leary as a finesse pitcher, similar to the way she pitched at Crescenta Valley and Long Beach.
