MINNEAPOLIS — Lindsay Whalen and Maya Moore scored 20 points apiece and Seimone Augustus added 18 to lead the Minnesota Lynx to an 85-62 win over Phoenix in Game 1 of the Western Conference finals on Thursday night.

Diana Taurasi scored 15 and Brittney Griner had 13 points and six rebounds for the Mercury, which now faces a must-win situation in Game 2 in Phoenix on Sunday.

Both teams started out cold but Minnesota recovered quickly and turned the first half into a mismatch. After hitting just one of their first six field-goal attempts, the Lynx made 16 of their next 23 shots, while Phoenix was just 9 for 37 (24.3 percent) for the half.

Whalen, a first-team All-WNBA pick, scored just 13 points in Minnesota’s two-game sweep of the Storm in the conference semifinals. That changed when she hit her first five shots and finished the first half 7 for 10 for 14 points.
