Dominique Wilkins' 10-footer off the baseline put Georgia ahead to stay and Wilkins came back with a slamdunk and two free throws in the final three minutes as the Bulldogs upset third-ranked Louisiana State, 68-60, to gain the final of the Southeastern Conference basketball tournament last night in Birmingham.

The Bulldogs, passing the semifinals for the first time in their history, will face Mississippi, which earlier demolished Vanderbilt, 71-51, in the championship game today.

Wilkins' go-ahead shot off the base-line gave the Bulldogs a 53-52 lead with 3:03 remaining.

The Georgia sophomore then stole the ball from LSU's Ethan Martin and Georgia held it until Wilkins got his dunk on an out-of-bounds play with 1:46 remaining.

Wilkins sank two free throws 13 seconds later to give Georgia a five-point lead and the Bulldogs protected it down the stretch as freshman Vern Fleming sank two free throws and also converted a three-point play.

LSU, which has a 26-game winning streak snapped by Kentucky Sunday, fell to 28-3 and became the third nationally ranked conference power to be ousted from the tournament.

Ole Miss upset No. 10 Tennessee and Vanderbilt upset No. 7 Kentucky Thursday.

In the first game, all-conference forward Elston Turner led a 23-4 outburst in the first five minutes of the second half for Mississippi.

Ole Miss (l5-l3) was down by two points before sophomore Carlos Clark tied the score at 20 with 33 seconds left in the half. Mississippi took a 22-20 halftime lead when sophomore Cecil Dowell made a 20-foot jumper as the horn sounded.

The Rebels were ahead, 4l-24 five minutes into the second half and led by 24 several times before Ole Miss Coach Bob Weltlich cleared his bench.
