Mykal Riley's 3-point barrage ended Florida's three-year run as SEC tournament champions, leaving the Gators' NCAA tournament hopes in doubt.

The Crimson Tide (17-15) was dominant in the first half but had a 28-point lead shrink to 6 before recovering to beat Florida (21-11) 80-69 Thursday night in the first round of the Southeastern Conference tournament.

Alabama ended Florida's streak of 18 consecutive postseason victories over two years while giving the Gators (21-11) their first SEC tournament loss since the 2004 championship game. Florida is in danger of missing the NCAA tournament after winning two straight national titles.

Riley tied the school record with eight 3-pointers and finished with 26 points. The senior guard snapped Florida's momentum with back-to-back 3s after the Gators pulled to 57-51 with 9:02 left.

Alabama will face Western Division top seed Mississippi State in Friday's quarterfinals.
