Mississippi scored three runs in the seventh inning to spoil a Kentucky rally and complete a series sweep with a 6-5 win in Oxford on Sunday.
Junior Braden Kapteyn hit a two-run homer as Kentucky scored five in the sixth to take a 5-3 lead.
But the Rebels hit back-to-back doubles to start the seventh, sparking a rally that sent the Cats to their 12th straight Southeastern Conference loss. Ole Miss won the three games by a total of four runs.
It was the fifth homer of the year for Kapteyn (0-2), but it was the junior designated hitter/reliever who gave up all three earned runs on two hits and two walks in the seventh, taking the loss after two-thirds of an inning.
UK starter Taylor Rogers gave up a run in each of the first three innings. He allowed six hits and four walks, striking out two over 52⁄3.
