Superb first-half goals from Franck Ribery and James Rodriguez gave Bayern Munich their 10th consecutive win in all competitions at Mainz.
Bayern Munich increased their lead at the Bundesliga summit to 18 points with a routine 2-0 win at Mainz.
Sandro Schwarz's hosts enjoyed moments of encouragement during both halves at Opel Arena but Bayern's extra class ultimately told.
Franck Ribery is seemingly back to top gear following his knee ligament injury at the end of last year and the former France star showcased his enduring class with a sweetly struck half volley to put Jupp Heynckes' men ahead.
