Seattle finished the first half of the season having taken two of three and aimed to carry that momentum into Wednesday afternoon, but fell behind early despite a push in the third. They were unable to recover and lost to Washington 87-74.
Seattle fell behind by 20 points after the first and slowly began to chip away.
Seattle tried to keep it close in the second, where Crystal Langhorne scored seven of her nine first half points. A pair of free throws from Markeisha Gatling at the end of the half cut the lead down to 16.
Seattle defense stepped up and held the Mystics to 38.1 percent from the field in the second.
Seattle came out in the third and quickly made a game of it. Ramu Tokashiki drove to the basket and connected on the scooping layup to cut the lead to 16 and then hit a running bank shot to make it 55-41.
Following a Washington timeout, Alysha Clark found Sue Bird on the left wing for the three and the Storm were within 11.
The Mystics responded with a 10-1 run to push the advantage back to 20 and went back up by as much as 24. But Seattle had one final push in the fourth and rode Abby Bishop and Quantira Hollingsworth for a 12-0 run to cut the Washington lead to nine.
Bishop finished one point short of tying her career-high with 17 on 6-for-12 from the field.
This marks the beginning of a six-game road trip for Seattle, and it will continue on Friday when the Storm takes on Connecticut at 4 p.m. PT.
