HERRIMAN, Utah (AP) — The Portland Thorns and the Chicago Red Stars played to a scoreless draw Wednesday in the group stage of the National Women’s Soccer League’s Challenge Cup tournament.

Portland dominated possession and outshot Chicago’s young lineup but couldn’t manage to score in a game without fans in Herriman, Utah.

Rookie Morgan Weaver had a good chance for the Thorns in the 14th minute but Chicago goalkeeper Emily Boyd got a hand on it and pushed it over the net. Raquel Rodriguez also had a shot from distance go just wide after coming in off the bench in the second half.

Chicago’s Savannah McCaskill had a free kick in the 85th minute that went wide.

The game was the second of the tournament for both teams. The Red Stars swapped out their lineup from the opener, with key players including Julie Ertz, Alyssa Naeher, Kealia Watt and Yuki Nagasato all on the bench. Red Stars coach Rory Dames has said he wants to give young players experience during the tournament.
