Rookie Riley Tiernan scored her first professional goal in the second half and Angel City defeated the visiting Seattle Reign 2-1 on Sunday night at BMO Stadium.

Tiernan’s goal came on a header in the 63th minute. She’s the third rookie to score in the league this year.

“Probably the highlight of my life, to be honest,” Tiernan said with a smile after the 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.

Gisele Thompson was subbed out of the game in the 74th minute with an injury.

Second-half sub Christen Press appeared to score a third goal for Angel City in the final moments of stoppage time but it was offside.

U.S. women’s national team coach Emma Hayes was among those in attendance.
