Bari, on a goal by Carmine Gautieri one minute into the second half, jolted previously undefeated AC Milan 1-0 on Sunday for its first victory of the Italian League season.
Gautieri finished an individual run with an angled shot past goalkeeper Sebastiano Rossi, helping Bari improve to 1-2-2 (five points).Milan's high-priced attackers, Roberto Baggio and Liberian-born George Weah, failed to produce on the road against one of the league's most porous defenses. Bari packed its defense and Gautieri's score was one of its few threats on offense.
Milan's hopes dimmed in the 70th minute when midfielder Demetrio Albertini was ejected for a foul on Bari's Paolo Annoni.
Milan (4-1-0, 12 points) remained alone in first place because Juventus of Turin and Napoli played to a 1-1 draw, leaving both with 11 points (3-0-2).
That set up a battle for the league lead between Milan and Juventus in two weeks. There are no league matches next Sunday because Italy plays Croatia in a European Championship qualifier Oct. 10.
AC Parma (3-1-1) got two goals from Bulgarian striker Hristo Stoichkov and beat last-place Padova (0-4-1) 3-1, moving into fourth with 10 points.
Also, Cagliari matched Bari's feat, gaining its first victory by handing Sampdoria of Genoa (1-1-3) its first loss 2-1.
On Sunday night, AS Roma and Lazio of Rome played to a scoreless draw.
In other games Sunday: Fiorentina beat Cremonese 3-2; Inter Milan routed Torino 4-0; Atalanta of Bergamo blanked Piacenza 2-0; and Udinese and Vicenza tied 1-1.
