WASHINGTON (AP) -- Diana Taurasi scored 31 points and fellow U.S. Olympian Cappie Pondexter added 28 as the Phoenix Mercury beat the Washington Mystics 98-90, halting the host's winning streak at three on Tuesday night.

The Mercury (5-7) bounced back from their worst loss in nearly six years, earning just their second road victory this season, a day after visiting President Bush at a White House ceremony honoring their 2007 championship.

The Mercury looked nothing like champions in a 33-point loss at New York to start their five-game road trip Sunday. But the league's highest scoring team, averaging 87 points, opened the third quarter with a 13-2 run and built a 16-point lead, 73-57, late in the third against Washington.

Taurasi and Pondexter, the league's top scorers, averaging just under 25 points, were among nine selections to the U.S. Olympic team on Saturday. The final three selections will be announced before July 1.

The Mystics' Olympic hopeful and leading scorer, Alana Beard, was limited to 11 points on 4-for-13 shooting. She was averaging 19.7 points per game.

Washington (5-8) was led by 37-year-old Taj McWilliams-Franklin, who scored a career-high 31 points on 12 of 14 shooting, while Monique Currie scored 19 points for the Mystics.

McWilliams-Franklin's jumper with 1:49 to play reduced Phoenix's lead to 90-84, but the Mercury sank free throws down the stretch to ice the game. The Mercury lead the league in free throw shooting at 83 percent and hit 17 of 19 from the line Tuesday night.

The Mystics led the league in 3-point shooting percentage, 39 percent, but hit just five of 20 from behind the arc.

Taurasi hit 11 of 15 shots, including 4-for-5 on 3-point attempts, and sank all five of her free throws. She also led Phoenix with eight rebounds and six assists. Tangela Smith scored 14 points for the Mercury. Pondexter was 10-for-18 from the field.
