PHOENIX — Brittney Griner scored 16 points, including her second dunk of the season during a key fourth-quarter stretch, as the Phoenix Mercury extended their franchise-record winning streak to 11 with a 90-78 win Tuesday night over the Washington Mystics.
The Mercury (17-3) ran off six straight points after Washington had cut the deficit to 73-65 with 8:43 left. Phoenix had led by double digits since the last three minutes of the first quarter.
Candice Dupree, announced as a WNBA all-star reserve earlier Tuesday, had 19 points, six rebounds and four assists for Phoenix, which has won 13 of 14.
Monique Currie scored 19 points to lead the Mystics, who had won back-to-back road games.
Diana Taurasi added 18 points, six rebounds and four assists for the Mercury.
Griner, who added eight rebounds and two blocked shots, has four dunks in her year and a half in the league. No other WNBA player in the history of the league has more than two.
Bria Hartley scored 15 points while Ivory Latta added 13 for Washington.
The Mystics trailed by 18 in the second half but were 10-of-14 from the field in the third quarter to stay within 73-60 entering the final period.
Dupree had 13 points and four rebounds in the first half as Phoenix opened up a 48-33 lead at the break.
The Mercury made 11 of their first 14 shots to grab a 32-14 in the first nine minutes. Griner added 10 points in the first quarter and a pair of blocked shots for Phoenix.
With more than a month left in the season, the Mercury has a magic number of three to clinch a playoff spot. Phoenix has been in the postseason four of the last five years, reaching the conference finals three times.
Phoenix beat Washington 81-66 on June 10 to sweep the season series.
