Harry Kane scored for the first time from open play since November and Bayern Munich stretched its Bundesliga lead to six points by winning in Freiburg 2-0 on Saturday. Bayern profited from defending champion Bayer Leverkusen’s 2-2 draw in Leipzig, where Florian Wirtz struck the post three times and the visitors were left to rue Edmond Tapsoba’s late own goal. Borussia Dortmund ended its four-game losing streak across all competitions in its first game since firing coach Nuri Sahin, but there was little celebration.
