(CNN) -- Two goals from Mario Mandzukic helped Bayern Munich to a 3-0 at Mainz on Saturday to increase their lead at the top of the Bundesliga to 14 points.
The in-form Croatian striker sealed victory for the runaway leaders early in the second half with goals in the 50th and 57th minutes after Thomas Muller had given Jupp Heynckes' side the lead four minutes before the break.
The win extends Bayern's unbeaten run in the league to 11 games and gives them a tally of 51 points for the season.
Second-placed Bayer Leverkusen, who could only manage a draw against Freiburg last weekend, face reigning champions Borussia Dortmund on Sunday.
