The yellow T-shirts with the imprint "Aufsteigerinnen 2022" were already ready, but the fact that the players from Alba Berlin will already be playing in the first division in the coming season came as a surprise.
"We had a completely different time horizon," said Managing Director Marco Baldi.
"But we're happy to accept that it's already happened."
For guard Lucy Reuss, success still feels a bit unreal.
"But I didn't think we'd do it so well." Alba is now the only basketball club where both men and women are top-notch.
2000 fans came to the arena at Ostbahnhof on Good Friday.
They saw coach Cristo Cabrera's team beat Rhein-Main Baskets 99-71 in the decisive semi-final second leg of the promotion play-offs and then celebrate their first promotion to the women's Bundesliga in yellow T-shirts.
Alba has big plans for the women.
"We've been saying for almost three years that we really want to support it.
And then we will also have a chance to make it to the top in women's basketball," said Baldi.
He hopes that the rise will have a signal effect.
"I can imagine that this will bring a push to women's basketball overall."
According to the club, around 400 girls and women play basketball in 24 youth and three adult teams.
From the current second division squad, more than half of the players (nine) are younger than 20 years.
“What we offered to boys, we always offered to girls.
And we're reaping the fruits now, so to speak," said Baldi.
The club can transfer the experience from the men's professional field to the women.
However, some organizational problems still have to be solved.
"We have the know-how and the infrastructure, but there is still a lot missing," said Baldi.
A suitable hall still has to be found - the current one is too small for the first division.
