Sancho Lyttle made a jump shot with 0.9 seconds 90 win over the Indiana Fever.
Lyttle had 14 points, 11 rebounds and five assists, guiding the playoff- hopeful Dream to a third straight victory. Angel McCoughtry had 28 points and Armintie Price 16 for Atlanta, which has won six of its last seven contests.
The Dream moved 2 1/2 games clear of Chicago for the final playoff spot in the Eastern Conference.
Despite the loss, the conference-leading Fever clinched a playoff spot as Chicago lost to the New York Liberty Tuesday night.
Erin Phillips totaled 21 points and Tamika Catchings 20 for the Fever, who have dropped two straight.
A jumper from Phillips gave the visitors a two-point edge with 1:16 left, but just seven seconds later Iziane Castro Marques made a jumper to tie the game.
Catchings missed a three-point try, Lyttle failed on two free throw attempts and a Price steal led to Lyttle's go-ahead bucket.
Phillips' three-point try at the end missed.
