(AP) -- While they've shown significant improvement of late, the Seattle Storm believe they can play at an even higher level.
The Eastern Conference-worst Washington Mystics can't be happy to hear that.
Visiting Seattle tries to extend its season-best winning streak to five Tuesday night as it concludes a home-and-home set with the Mystics, losers of seven of eight.
The Storm dropped seven of their first eight games before their current run. After winning 86-73 at hapless Tulsa on June 15, Seattle knocked off then-undefeated Minnesota and San Antonio before concluding its homestand Sunday with a 72-55 victory over Washington (2-8).
Sue Bird and Ann Wauters each scored 14 points for the Storm, who shot 56.3 percent and limited the Mystics to 34.9 percent from the field. Seattle last won five in a row during a 13-game run June 18-July 30, 2010.
"I think we're playing better, but I think there is still more to go," Bird said. "We still kind of have some lapses here and there. It will probably happen throughout the season, but the more we can minimize them. We still have a long ways to go."
Seattle (5-7) could surely benefit from a better effort on the glass. The Storm were outrebounded 29-23 on Sunday and allowed Washington to collect 13 offensive boards compared to their two - both grabbed by Wauters.
"That's an area where we're going to have to get better at," coach Brian Agler said. "Whatever it was is not going to play well for us on Tuesday."
Sunday marked the last of three consecutive road games for the Mystics, who scored nine points in the second quarter on 4-of-19 shooting.
"I felt like we were mentally fatigued," coach Trudi Lacey said. "When our shots didn't fall, it took the wind out of our defense."
Leading the team with 16.1 points per game, Crystal Langhorne scored a game-high 21 on 9-of-15 shooting as the Mystics fell to 0-5 on the road.
Langhorne had 22 points and 13 rebounds during Washington's last home game, a 67-66 win over Indiana on June 15. The Mystics haven't posted back-to-back victories in Washington since winning their final five home games during the 2010 season.
The Storm had dropped four straight road meetings with the Mystics before recording a 73-63 win July 3.
Seattle and Washington, averaging 68.7 and 68.6 points, are the two lowest- scoring teams in the league.
