Hamburger SV moved a step closer to Bundesliga relegation with a 4-0 defeat at Bayer Leverkusen in sports director Peter Knaebel's first game as interim coach on Saturday. Knaebel, who took over from the sacked Joe Zinnbauer, restored Rene Adler in goal, but Adler was picking the ball out his net in the seventh minute, when sloppy defending allowed Gonzalo Castro an easy score. Castro set up Stefan Kiessling in the 44th, then again in the 56th, before completing the scoring on another counterattack in 63rd. Wolfsburg consolidated second place with a 3-1 home win over Stuttgart. Fourth-place Borussia Moenchengladbach won 4-1 at Hoffenheim. Werder Bremen drew 0-0 with Mainz, Hannover drew 2-2 at Eintracht Frankfurt and Freiburg beat Cologne 1-0. Borussia Dortmund was hosting Bayern Munich later.
