German Bundesliga leader Borussia Dortmund missed a penalty and conceded a last-minute equalizer in a 1-1 home draw with Mainz 05 on Saturday that extended its advantage at the top to 10 points.

Defender Mats Hummels gave Dortmund an early lead but it was left fuming when Petar Sliskovic equalized from close range in the 89th minute with Dortmund's Neven Subotic down injured in the box with the referee allowing play to go on.

Dortmund has 62 points with seven games left, ahead of second-placed Bayer Leverkusen which was hosting Schalke 04 yesterday.

"This is a fair result in a way," said Dortmund coach Juergen Klopp. "Mainz were a tough opponent and for us a lot went wrong today. We missed a penalty and then had to take (striker Lucas) Barrios off."

Barrios went off injured late in the first half after colliding with Mainz goalkeeper Christian Wetklo.

Franck Ribery scored an 88th-minute goal to give fourth-placed Bayern Munich a nervy 2-1 win at SC Freiburg that keeps it in the hunt for a Champions League spot.

Ribery fired in a low left-footed drive to break the host's gutsy resistance and lift the champion to 48 points, two behind Hanover 96 which beat Hoffenheim 2-0.

Michael Oenning's debut on the Hamburg SV bench was a success as his team crushed Cologne 6-2 with a hat-trick from Mladen Petric.

Ze Roberto, who matched the Bundesliga record for most games by a foreign player when he made his 330th appearance, was also on target converting a second-half penalty.

Werder Bremen beat Nuremberg 3-1 to move four points above the drop zone while Eintracht Frankfurt got its first win
