LSU broke open a scoreless tie with a seven-run fourth. Right fielder Quinn Stewart started the barrage with a RBI single, scoring third baseman Will Harris who reached on a double to start the frame.
Two defensive miscues by the Ospreys, including a throwing error by pitcher Jacob Dixon, brought home shortstop Michael Hollander.
With the Tigers leading 4-0, center fielder Jarred Bogany drove in a run on his third single of the game followed by a bases-clearing two-run double from designated hitter J.T. Wise.
Dixon was lifted just before the rains came after surrendering six runs on 11 hits in 3.1 innings of work.
Meanwhile, LSU starter Clay Dirks cruised through the first four innings, limiting UNF to two hits on 60 pitches. The senior racked up six strikeouts, just two shy of his career-high.
