FRANKFURT, April 15 (Reuters) - Michael Ballack and Mehmet Scholl struck second-half goals to give Bayern Munich a 2-0 win over Arminia Bielefeld on Saturday, keeping the champions four points clear of Hamburg SV with four games left.
Hamburg, doing their best to keep the Bundesliga title race alive, enjoyed a 2-0 win at MSV Duisburg, with both goals coming in the first half.
For a long time that looked like being enough to cut the Bayern lead in half but Ballack drilled in with 21 minutes to go and substitute Scholl wrapped up the points with another long-range strike five minutes later.
With 30 games played, Bayern lead with 69 points and remain on course for a 20th German title. Hamburg are second on 65, with Werder Bremen in the third and final Champions League slot with 60 points after a 1-1 draw at VfL Wolfsburg.
Schalke 04 are fourth on 54 after sneaking a 1-1 draw at home to second-from-bottom Cologne.
