( CNN ) -- Bayer Leverkusen moved to within three points of German Bundesliga leaders Bayern Munich after a comfortable 4-2 home victory over Hamburg on Sunday . A double from Stefan Kiessling helped Leverkusen on their way to another three points , leaving them clear in third , a point behind second-placed Schalke , with the top three now pulling away in the race for the title with just eight games left . Kiessling opened the scoring after running onto Tranquillo Barnetta 's through-ball and out-pacing two defenders before firing past goalkeeper Frank Rost . But Ze Roberto volleyed home a 33rd-minute equalizer for Hamburg after a defensive mix-up involving Sami Hyppia and goalkeeper Rene Adler . Eren Derdiyok restored Leverkusen 's lead in the 55th-minute when heading home Daniel Schwaab 's ball into the box -- and Kiessling quickly added a third with a simple tap-in after some great work from Renato Augusto . Czech defender David Rozehnal gave Hamburg some brief hope when converting an 83rd minute Piotr Trochowski free-kick but the victory was confirmed just a minute later when Gonzalo Casto fired home from just inside the area . Meanwhile , in the day 's other match , Claudio Pizarro scored his 11th league goal of the season to give Werder Bremen a 1-0 home win over Hoffenheim . The Peruvian striker lobbed goalkeeper Timo Hildebrand with just nine minutes remaining to leave Werder sixth in the table , one point away from a place in Europe .
