DAYTON, Ohio (AP) - Chris Johnson scored 20 points and Dayton closed with a 17-9 run to knock off No. 16 Alabama 74-62 Wednesday, ruining Crimson Tide head coach Anthony Grant's homecoming.

Grant starred for the Flyers from 1983-87. Alabama fell behind 38-27 at halftime with star forward JaMychal Green on the bench most of the first half with two fouls. Green scored the Tide's first six points and finished with 12 on 6 of 9 shooting.

Dayton (6-3) led 56-40 with 11:52 to play when Alabama increased its defensive pressure to cut its deficit to 57-53 with 7:43 left.

Dayton point guard Kevin Dillard answered with consecutive 3-pointers and Dayton was on its way to its third win this season over a BCS conference team. The Atlantic-10 Flyers have now won nine of their last 10 games against BCS opponents.
