San Diego Wave FC experienced its first stumble of the regular season Wednesday, falling to Racing Louisville FC 1-0.

The team was without coach Casey Stoney, who was left behind in San Diego after testing positive for COVID-19. But the defense remained sound, with only a free kick by Louisville making it past the team’s back line and through the goaltender.

“It was a frustrating evening for us,” said Wave assistant coach Rich Gunney, who took over for Stoney in the interim. “Obviously, we’re disappointed with the result. It’s tough on the road, especially with a short turnaround.”

Savannah DeMelo was the owner of said free kick in the 27th minute. She sent one high into the net from roughly 30 yards out to put the Wave behind for the first time in the new franchise’s regular-season history. The goal made SportsCenter’s top 10 plays for the day, coming in at No. 10.

It’s just the second goal scored on San Diego through four matches this season. It’s also the first win of the season for Racing Louisville. The team has been dealing with a COVID-19 outbreak, which limited practice time and led to some reshuffling in the lineup.

“It shows that we have a lot of depth on this team,” DeMelo said postgame. “No matter if you never play or if you play all 90 minutes, once you step on the field, I think everyone is equal. I think it showed these past two games.

“I’m just really excited that we got our first win under all those circumstances, and now we know what we have and just carry it forward to this weekend.”

Both sides generated nine shots over the course of the match, with Racing goalkeeper Katie Lund making four saves on the evening.
