Leading 2 - 0 from the away leg, they beat Barbastro 1 - 0 with a goal from Victor Vazquez [contemporary and good friend of Leo Messi].
[Match report from the official website.]
The club had made a massive effort to fill the Miniestadi, which paid off with more than 10000 there at the game, the sort of numbers not witnessed since the B team of De la Pena and co, years and years ago.
Overall, B team have performed admirably in the play-offs, scoring 9 goals in total and conceding none in two-legged ties against Castillo and then Barbastro. [God, I'm so proud of them.]
Coach Pep Guardiola [the incoming first team coach, for those of you who have been living under a rock] proved himself very similar to Frank Rijkaard in one respect: at the end of the match, he shook hands with the opposing coach and disappeared down the tunnel, leaving the spotlight to his players and their crazy celebrations.
He didn't spare his successor, Barca legend and good friend Luis Enrique any pressure at the press conference afterwards, stating that promotion to the Segunda Divison would be the B team's aim next season.
[The phrase 'the declarations of Pep Guardiola' put an enormous grin on my face. Seriously, though, the man needs more joy in his life. Smile, Pep, smile!]
