Oak Mountain and Briarwood Christian each posted 10-0 mercy rule victories in the first round of the Alabama High School Athletic Association girls soccer playoffs Tuesday.

Shannon Lathrop scored a hat trick in the first 15 minutes of the game to help the Lady Eagles, ranked third in Class 6A, silence Northridge.

“It was definitely good to start the game out strong,” said Oak Mountain head coach Kelly Christoffer.

The Lady Eagles stretched the lead to 8-0 before halftime with three goals coming between the 21st and 26th minutes and a pair of goals by Marissa Tomasewski in the 32nd and 35th minutes.

Lauren Byrd collected three saves in the net, while Northridge’s Victoria Sherwood had 10.

Oak Mountain (14-6-2) travels to Huntsville High for a second-round game Friday. Huntsville defeated the Lady Eagles 3-2 earlier in the season.

Briarwood also took advantage of a hat trick in its 10-0 win over Chelsea, as Abbie McCary scored goals in the 12th, 16th and 47th minutes of the match.

The defending 5A state champion Lady Lions took advantage of 21 shots in the first half to take a 7-0 lead into the break. They scored three goals off just seven shots in the second period, including a goal from Rachael Jones in the 53rd minute to call the game. Senior captain Morgan Haney had two goals within the first 14 minutes of play.

“I was real proud about the way they played at the beginning of the game,” Briarwood head coach Ryan Leib said. “We challenge the girls to play their best soccer no matter who the other team is.”

The top-ranked Lady Lions (16-3-1) travel to No. 7 St. Paul’s Episcopal on Friday for a second round match.

Chelsea ended their season 6-8-4 after making the playoffs for the first time in five years.

“We knew what we were up against. Briarwood is a great team, and we’re not at that level yet,” Chelsea head coach Samantha Corker said. “I feel pretty good though, having just lost 10-0, because these are a great group of girls and fans we had here tonight.”

Indian Springs also collected a first-round shutout, defeating Holy Spirit 8-0 on the road. Anchal Bansal and Devon Weldon each posted a hat trick. ISS travels to Trinity this weekend.

Thompson High School also qualified in Class 6A, falling to top-ranked Vestavia Hills 6-1. Marry Morris scored the Lady Warriors first-ever postseason goal off a direct kick in the first half
