Lowary will have two seasons of eligibility remaining in Norman. It was not immediately clear if she had been granted a release from Missouri and would be able to play right away in 2017, or if she will have to sit out a season per NCAA rules.
Sources did confirm to Justin's World of Softball that Lowary was one of the players at the center of the controversy that led to the school's investigation of head coach Ehren Earleywine for alleged verbal abuse of players.
During her Tiger career, Lowary recorded a 43-15 record with a 3.33 ERA and 315 strikeouts. In the Tigers' hosted Regional last season, Lowary pitched every one of her team's games, becoming the first and only pitcher in NCAA history to be in the circle for three run-rule victories and sweep the Regional round of games.
In joining the defending-champion Sooners, Lowary joins forces with Paige Parker to give Patty Gasso one of the best pitching staffs in the nation and some experienced depth in the circle.
Lowary has spent the summer as part of the USA Elite team for the second year in a row.
