Stone and Rubadue, who respectively stamped their tickets for the NCAA championships Monday in the men's 1-meter and women's 3-meter springboard events, needed top 12 finishes in Tuesday's competition to add the event to their national meet schedule.
Stone took second place in the men's 3-meter competition with a two-list combined score of 841.25, throwing in a new dive in the evening finals for possible preparation for NCAAs. He finished ninth at the NCAA meet last year, winning the consolation final.
"Liam did some really good stuff today," Tennessee diving coach Dave Parrington said. "Based off his prelim effort, we decided to gamble a little and try a dive in the final he had only done once before in competition, an inward three and a half. It's something we might use at NCAAs. With Liam, there was confidence there in doing that."
Rubadue climbed to ninth in the women's 1-meter finals with a combined score of 548.50. She dove more than 30 points better in the finals than the prelims, posting an evening six-dive list of 291.25.
"Rachel needed to hit her last dive in prelims to make the finals," Parrington said. "She did that and then scrapped her way up the standings. I was very pleased with the competitive spirit she showed today."
