McCoughtry scored seven straight points — on a 3-pointer, bank shot and pull-up jumper — to cap Atlanta's 19-5 run to start the fourth for an 85-71 lead. She collided with Breanna Stewart on Seattle's next possession and stayed on the ground before being helped to the bench by the Atlanta staff. She later returned.
Bria Holmes added 21 points for Atlanta, which will face the Chicago Sky on Sunday. Atlanta was without its second leading scorer Tiffany Hayes, who was serving a one-game suspension after picking up her seventh technical foul. The Dream's second leading rebounder, Sancho Lyttle, did not play because of a foot injury.
McCoughtry, who picked up her fourth foul early in the third, made two free throws with 1:11 left in the quarter to give Atlanta a 66-64 lead — its first since 21-20.
Jewell Loyd scored 24 points and Stewart added 19 points in their first career playoff games for Seattle. Stewart had 15 points in the first half and Loyd scored 12 as Seattle held a 45-37 halftime lead.
Before the game, Atlanta forward Elizabeth Williams was named the WNBA's Most Improved Player.
The game was played at Georgia Tech, where the Dream will play for the next two seasons.
Tamika Catchings, who played in her final game, and the entire Indiana team knelt with their arms intertwined during the national anthem. Two members of the Mercury, Kelsey Bone and Mistie Bass, also took a knee.
"This game of basketball is important for a lot of reasons. One of them is bringing people together. Even uniting people," Catchings said about the "impromptu" kneeling during the national anthem. "Well, we thought it was important to have a voice about something greater than basketball."
WNBA president Lisa Borders, who was in Atlanta for the playoff game between the Dream and Seattle backed the players choice to kneel.
"I support our players expressing their views on important social issues," Borders said in a statement. "Standing for an anthem is a sign of respect and a demonstration of unity across many cultures throughout the world. The call to action is for all of us to invest time and resources to help rebuild and strengthen our communities. And we have been actively working with the players on this next impactful effort."
Briann January made a reverse layup with 2:39 remaining to pull Indiana to 77-72 and she drew an offensive foul on Taurasi on the other end. Erlana Larkins had a putback on Indiana's next possession to cap a 10-1 run to make it 77-74.
But Phoenix answered with a 6-1 run — on free throws by Taurasi, Penny Taylor and Bonner — for an 83-75 lead.
Brittney Griner added 18 points, nine rebounds and three blocks for Phoenix, which will play at New York on Saturday. Bonner was just 2-for-5 from the field in the first half.
Catchings and Marissa Coleman (Maryland) each scored 13 points as all five starters for Indiana scored in double figures.
Shenise Johnson made two free throws to tie Tiffany Mitchell's franchise record with 42 consecutive made free throws.
Catchings left the floor at the final buzzer to a standing ovation from the crowd and she hugged every Indiana teammate, including a long embrace with January. Then she hugged each player on the Phoenix team.
Before the game, Catchings received the 2016 Kim Perrot Sportsmanship Award prior to the opening tip. She is the first three-time winner since the award's inception in 1997.
