Racing Louisville won at Chicago 1-0 after a two-hour weather delay in the day's earlier game.
Alyssa Thompson scored for Angel City in the eighth minute with a hard strike from the top of the box. She yelled in celebration before she was embraced by her sister Gisele Thompson, a defender on the team.
It was Alyssa Thompson's second goal of the season.
The Reign pulled even some four minutes later when Ji So-Yun converted on a penalty.
