Brittney Griner scored 18 points and the Phoenix Mercury tied the second-longest winning streak in WNBA history with their 15th straight victory, beating the New York Liberty 78-63 on Saturday night.

The Mercury (21-3) matched the 1998 Houston Comets with the victory and are three short of the league mark set by the Los Angeles Sparks in 2001.

Griner also had eight rebounds and six blocks, and Diana Taurasi added 15 points, 10 assists and five rebounds for Phoenix, which clinched home-court advantage in the first round of the playoffs.

Tina Charles had 20 points and seven rebounds to lead New York (10-14). The Liberty had won three in a row and six of their last eight.
