Penny Taylor led the Mercury with 13 points and veteran guard Diana Taurasi scored 11 points for the 2009 champions, who were 19-15 in the regular season and finished third in the West.
The teams finished the first quarter tied at 19, but Seattle asserted its dominance over the Mercury the rest of the way, outscoring them in each of the final three quarters, including a 29-11 thumping coming out of halftime.
