Kevin Grosskreutz hit a last-gasp goal to help Borussia Dortmund beat Cologne 3-2 at home in the Bundesliga on Sunday. Mats Hummels hit a brace for the hosts on 28 and 45 minutes, and Dortmund kept their two-goal cushion for more than half an hour. Cologne's Kevin McKenna pulled one back on 82 minutes while Youssef Mohamad equalized six minutes later. But Grosskreutz hit the winner for the home side in stoppage time. Now fifth-placed Dortmund are on 33 points, five behind leaders Bayer Leverkusen.
