Ruth Riley scored 20 points, including the game-winning basket with one second left, to lead the Detroit Shock over the Silver Stars, 60-59, last night in San Antonio.
Shannon Johnson's turnaround jumper for the Silver Stars near the three-point line bounced off the back of the rim as the buzzer sounded, giving the Shock (14-14) its fourth straight win.
Detroit is one-half game behind Washington for the fourth and final playoff spot in the Eastern Conference. The Shock has not been at .500 since July 7.
"I think that we will need to finish at least 4-2 to be assured of a playoff spot," Shock Coach Bill Laimbeer said.
The Silver Stars (7-23) lost their fifth straight game.
Riley's game-winner came when she rebounded Katie Smith's missed shot on a drive into the lane with three seconds left.
"Once Katie's shot went up, it was just a matter of being in the right place at the right time," said Riley, who topped her previous season high of 11 points.
