The Baggies went down 2-0 to Sunderland Ladies thanks to goals either side of half-time, but they matched one of the division’s strongest teams for much of the contest.
Sunderland finished second in National League Northern Premier Division last season, the league Albion won promotion into after winning the Division One Midlands title.
After the opening game of the season, manager Louis Sowe said: “Without being cliche there were a lot of positives which sets the standards for this season.
“Against the early favourites it was a creditable performance from us, and I’m proud of all the players.
“Shout out to Jaye Walker who stepped in goal for us this week after a few seasons out.”
Sowe’s sentiments were echoed by player Fran Orthodoxou, who said: “Personally feel we deserved more than what the scoreline shows but it was important to put a stamp down as to why we deserve to be in this league.
“Plenty of positives but back to the training ground we go to tighten up on a few things ahead of the rest of the season.”
Albion’s next league game is at home to Burnley at Walsall Wood FC on Sunday, September 1.
Season tickets cost £45 and covers entry into all league games as well as Birmingham FA County Cup matches.
