Diana Taurasi added 17 points, nine assists and six rebounds for Phoenix (18-13), which is trying to lock down the third playoff spot in the Western Conference. The Mercury lead Seattle by three games and can clinch the third seed with one more win or a Storm loss. Seattle hosted Minnesota later Tuesday night.
The Mercury will visit Chicago before closing the regular season against San Antonio and Los Angeles.
