The Chicago Sky are locked in as the No. 4 seed in the upcoming WNBA playoffs, but the Seattle Storm will be jockeying for position when the teams meet in the final game of the regular season on Sunday at KeyArena in Seattle.

Chicago (18-15) is second in the Eastern Conference, 2 1/2 games behind the New York Liberty and 1 1/2 games ahead of the Atlanta Dream, which lost to the Minnesota Lynx on Saturday.

The Sky, who will be without star Elena Delle Donne when they play Seattle, will enjoy a first-round bye as the fourth seed in the playoffs regardless of the outcome of Sunday's game.

Seattle (15-18) and the Phoenix Mercury are tied for third in the Western Conference. Seattle and Phoenix both have clinched playoff berths with one game remaining on their regular-season schedules. One will enter the playoffs as the No. 7 seed, the other as the No. 8 seed.

Seattle won the season series against Phoenix and would hold the tiebreaker advantage if it finishes with identical records. Neither team can move ahead of the Indiana Fever for the sixth seed because the Fever won the season series against Seattle and Phoenix.

Seattle has won six of nine games since the Olympic break. The Storm are coming off an 86-62 loss to Phoenix. Breanna Stewart had 14 points and nine rebounds, and Jewell Loyd and Kaleena Mosqueda-Lewis had 11 points apiece for Seattle.

Chicago has won three in a row and seven of nine since the Olympic break. The Sky are coming off a 92-68 victory over the New York Liberty. Both teams sat key starters, including Delle Donne and Tina Charles. Tamera Young had 22 points and nine rebounds for Chicago. Allie Quigley came off the bench to score 18 points.

Delle Donne, who is second in the WNBA in scoring at 21.5 points per game, underwent surgery on her injured right thumb on Tuesday. The team has provided no timetable for the return of the reigning WNBA MVP, but Delle Donne tweeted that she will "be back on the court in no time."
