BERLIN (AP) -- Borussia Dortmund piled the pressure on its Bundesliga title rivals Friday with a hard-fought 2-0 win at Nuremberg to move three points clear ahead of the rest of the weekend's games.
Sebastian Kehl fired the defending champion ahead in the 48th minute after Moritz Leitner split the Nuremberg defense and Lukasz Piszczek pulled the ball back for the Dortmund captain to slot into the corner.
Lucas Barrios sealed the win in the 82nd, following up on a rebound to score his first goal of an injury-plagued season.
Dortmund stretched its unbeaten run to 14 games.
Bayern Munich can reclaim the lead on goal difference with a win at Hamburger SV on Saturday, when Schalke can also move level on 43 points with a win against Mainz at home.
