Goals: 1-0 Maxim (2'), 1-1 Walace (9'), 2-1 Bell (52'), 3-1 Latza (58'), 3-2 Salihovic (pen., 90+2')
Despite Mainz leaving out top scorer Yoshinori Muto, it only took Sandro Schwarz's side two minutes to take the lead: Levin Öztunali's clever pass found Giulio Donati, whose equally clever cutback was converted coolly by Alexandru Maxim. The hosts' weaknesses defending set-pieces were again exposed soon after, however, when Walace capitalised on a loose clearance to lash in Hamburg's first goal since Matchday 2. From that point on, the visitors were dominant and should have gone ahead in the 42nd minute, only for Andre Hahn to shoot against the bar with the goal at his mercy.
As is so often the case, having failed to make their dominance count in the first half, Hamburg fell behind at the start of the second period, some lax defending from a corner allowing unmarked Stefan Bell to head into an empty net at the back post. Buoyed by the goal, Mainz extended their lead soon afterwards, Danny Latza making up for hitting the bar in the first half by sweeping a powerful effort past Christian Mathenia from the edge of the box. The hosts were largely untroubled until Sejad Salihovic's injury-time penalty caused a scare, but Mainz held on to make it three games unbeaten.
Man of the match
Although not on the score sheet, Öztunali was irrepressible for Mainz, playing a key role in his side's opener and delivering the corner from which Bell headed the 05ers back into the lead. The 21-year-old is flourishing this season and Hamburg will be ruing the 2013 decision to allow him to leave.
