Freshman shortstop Cale Iorg reached on a two-base throwing error by UL shortstop Micah Cockrell and Rice took third on the play. Bush then lifted a sacrifice fly to center to score Rice from third with the four-run lead.
UL cut the lead in half in the sixth inning when Dallas Morris drilled a two-run home run to left center field off Downs. It was Morris' 12th home run of the season.
The Cajuns added another run in the ninth when Justin Morgan led off with his fourth home run of the year.
Downs left after the home run to Morris and Davis came on to retire the next three batters for the save.
Rice and Thomley had two hits apiece and accounted for four of the Tide's seven hits in the win.
