SEATTLE -- A slow start resulted in yet another loss for the Connecticut Sun.
Tina Thompson and Camille Little each scored 18 points Thursday as Seattle won 78-65 in front of 5,567 fans at KeyArena.
Trailing 22-12 after one quarter and 40-23 at halftime, Connecticut was doomed to its 21st loss in 28 games.
The Storm (15-14) maintained its hold on the Western Conference's fourth and final playoff spot. Seattle can clinch with one more win and one more San Antonio loss.
Tina Charles scored 18 points to lead the Sun, which moved within another loss of potentially being eliminated from playoff contention. A year after winning the Eastern Conference regular season title, Connecticut (7-21) will probably finish with the WNBA's worst record.
Renee Montgomery added 15 points for the Sun and Tan White chipped in 12. Connecticut trailed by double figures for most of the game's final 34 minutes and dropped its sixth straight game.
Temeka Johnson added 12 points and nine assists for the Storm, while Shekinna Stricklen kicked in 11 points.
Seattle hit 48.9 percent of its field goal attempts and drilled 26-of-33 foul shots, making four more free throws than the Sun attempted. Connecticut had a miserable shooting game, sinking only 23-of-61 (37.7 percent) from the field and 1-of-10 3-pointers.
The Sun finish their West Coast swing Saturday night in Phoenix at 10 p.m.
