League MVP Breanna Stewart top-scored for the Storm with 30 points to earn the nod as the Finals' best player after averaging 25.6 points across the three games.
The Seattle Storm could clinch their third WNBA championship on Wednesday.
The 24-year-old was also named the WNBA Finals MVP on Wednesday following her 30-point performance.
The coach sensed something brewing early in his first year with the franchise.
Seattle converted 13 of 26 shots behind the arc, while Washington never found the mark behind the arc.
After trailing 69-53 entering the fourth quarter, the Mystics rallied to within five points at 72-67 on a 3-pointer by Tierra Ruffin-Pratt with 6:49 remaining.
"I'm still trying to find the right words, and I'm a guy that can usually find the right words", Hughes said after the game. "They've just said, 'OK, whatever you put in front of us, we'll deal with it'".
Although most of the team didn't shut their eyes until they got on a plane this morning, they said it was worth it to see all the fans waiting for them when they got home.More news: Candidates crisscross city ahead of Primary Day

"You're only going to impact [Delle Donne and Toliver] to a degree", Hughes said. In Game 2, the Mystics missed all 16 of their three-point attempts, any of which would have been the difference in a two-point loss.
Now she can add a WNBA title and a WNBA Finals MVP to her resume. Washington finished 8 of 23 on 3-pointers in Game 3 and 11 for 60 (18.3) in the series.
"We understand that we have to take care of the ball", Bird said. It didn't go our way, but you've got to keep things in perspective, and everybody else in the league wishes that they were playing tonight, and so we're very aware of that and thankful that we were here, and we know we can improve. We feel like we've got a lot of young, great talent, and obviously this isn't how we wanted it to end, but it's an experience that we can grow from.
"We were up at halftime, but we knew D.C. was going to come back", Stewart said.
"But when it got to eight, we kind of - we were calm". While players haven't been shy about standing up for themselves, they've gotten some help from their National Basketball Association counterparts this year, which is enormous given the men's game's meteoric rise both at home and overseas over the last half decade.
This is likely just the beginning for the dynamic 24-year-old forward, who won the NCAA Championship during each of her four seasons at the University of CT.
Bird understands her career is nearing the end, even though she remains among the league's best. Stewart dropped 17 points in the first half, too, going a flawless 4-of-4 from behind the arc.
"I'm sure [President Trump] is going to say we're not invited anyway", the Storm guard told KING 5, "so it all works out well".
