The NWSL postseason begins Sunday with four teams competing for the league’s title, with a doubleheader featured live on FOX Sports 1 beginning on Sunday the 13th at 1:30 p.m. EST.

This begins the completion of one of the NWSL’s most exciting seasons. The final four teams feature several women who played for their countries in the recent 2015 Women’s World Cup in Canada, including members of the world champions from the U.S. Women’s National Team.

The Chicago Red Stars, lead by U.S. internationals Christen Press and Julie Johnston, will be playing in their first playoff game, facing an FC Kansas City team whose lineup includes Americans Becky Sauerbrunn, Heather O’Reilly and Lauren Holiday.

Carrying over from FOX’s Women’s World Cup coverage, Jenn Hildreth will provide play-by-play analysis alongside Kyndra de St. Aubin and sideline reporter Julie Stewart-Binks. All three women will be broadcasting live from Toyota Park in Bridgeview, Illinois.

Immediately following the game in Illinois, Mark Rogondino, Aly Wagner, and Katie Witham will be live in Memorial Stadium’s Moda Pitch in Seattle, covering the Seattle Reign’s matchup against the Washington Spirit beginning at 9:30 p.m. EST.

The Reign finished runners up last season and are looking follow this year’s first-place regular season finish with a championship behind Megan Rapinoe, Hope Solo and Scotland international Kim Little. The Spirit, including Aly Krieger and Crystal Dunn (2015 NWSL Golden Boot honoree), are looking to make it to their first ever finals match.
