Rivals Portland and Seattle play to 0-0 draw in NWSL (The Associated Press)

The Portland Thorns and Seattle Reign played to a scoreless draw in a rivalry match that drew 18,114 fans to Providence Park on Sunday, even without the U.S. national team stars playing. Michelle Betos had four saves in her third start of the season for the Thorns, who remained the National Women's Soccer League's only undefeated team. Portland (3-0-4) was without goalkeeper Adrianna Franch, defenders Emily Sonnett and Meghan Klingenberg and midfielders Tobin Heath, Lindsey Horan and Allie Long, who have all been called up to the U.S. national team.
