(CNN) -- Brazilian ace Grafite grabbed a double as VfL Wolfsburg stayed three points clear of defending champions Bayern Munich with a 2-1 win over Bayer Leverkusen on Saturday.
Grafite is congratulated by a teammate after Wolfsburg's 2-1 home win.
It was the 10th straight Bundesliga win for Wolfsburg with Grafite's goals a key factor.
He tops the league scoring charts with 22 goals, none more crucial than his 85th minute winner to claim the three points.
Wolfsburg, unbeaten this season at home under coach Felix Magath, took the lead when Grafite was pulled down and got up to convert the penalty in the 23rd minute.
Leverkusen drew level through Tony Kroos in the 54th minute before Grafite popped up late to coolly convert.
Magath's former team Bayern Munich kept doggedly in the hunt as Italy World Cup star Luca Toni scored the only goal of the game at Arminia Bielefeld.
Toni headed home from a Franck Ribery corner just after the hour mark, the win taking the pressure off coach Juergen Klinsmann for the time being.
Bayern went out of the Champions League to Barcelona in midweek and he has come under criticism from demanding fans and former players of the Munich giants.
