The struggling Chicago Sky host the WNBA's hottest team in a Wednesday matinee at Allstate Arena.
The Los Angeles Sparks (18-1) carry a seven-game winning streak into the clash and need just two victories to match the now-defunct Houston Comets' record 20-1 start in 1998.
Chicago (8-11) has dropped four of its last six games while searching for a winning combination. The Sky are fifth in the WNBA Eastern Conference after employing their fifth different starting lineup of the season in last Sunday's 100-95 victory over Phoenix.
Nneka Ogwumike tops the Western Conference-leading Sparks with a 19.1 scoring average and 8.4 rebound average and leads the WNBA with a .701 shooting percentage. Chicago-area native Candace Parker is next, scoring at an average of 16.9 points
Chicago's Elena Delle Donne is second in WNBA scoring, averaging 20.9 points and 7.3 rebounds per game. She collected a season-high 38-points in an 87-82 loss to Minnesota on July 5 in Minnesota.
Guard Allie Quigley, usually first off the bench, had 29 and 21 points in Chicago's last two games.
Delle Donne will travel to the Rio de Janeiro Olympics later this month as a member of the U.S. women's national team.
The Sparks beat the Sky 98-85 on June 14 in Los Angeles as Ogwumike topped all scorers with 27 points and 12 rebounds.
Parker has dominated previous meetings as Los Angeles has taken five straight and six of eight from Chicago over the past three seasons. She has averaged 22 points and 7.2 rebounds in those games.
