Washington 89, Seattle 57

WASHINGTON, July 20 (AP) -- Taj McWilliams-Franklin scored 22 points and Alana Beard tied a career-high with nine assists as the Washington Mystics, in their first game following a coaching change, snapped the Seattle Storm's seven-game winning streak with a shocking 89-57 win on Sunday.

The Mystics (9-14), one day after head coach Tree Rollins was fired, hit 10 3-pointers, including five in the second quarter when they outscored the Storm 25-8 to take a 48-25 halftime lead and held on for their largest margin of victory on the season.

It was also the biggest blowout of the year for the Storm (15-8), who entered the game in a statistical first place in the Western Conference. Seattle was held to its lowest scoring output of the season. The Sonics were led by reserve Katie Gearlds with 13 points. Sue Bird added 11 and Camille Little had 10.

Coming off consecutive demoralizing losses by a combined 58 points, the Mystics played with a sense of urgency right from the start under interim head coach Jessie Kenlaw, who is in her first season with the Mystics after four seasons as an assistant with the Storm. Under her watch the Mystics set a franchise record with their 23-point halftime lead and the 48 first-half points was a season-high for the league's lowest scoring team.

McWilliams-Franklin sparked the second quarter surge by scoring 12 of the Mystics first 14 points, hitting all five of her field goal attempts, including two from beyond the arc. Nikki Blue made all three of her 3-pointers and Monique Currie added 12 points for the Mystics.

They split the season series with the Storm, who played their second game without all-star center Lauren Jackson, who is with the Australian Olympic basketball team preparing for the upcoming games.

The Mystics 64-49 loss to the Storm on June 29 was start of the Storm's winning streak.
