Bundesliga top-scorer Robert Lewandowski's 25th goal of the season was enough for Bayern Munich to comfortably beat Cologne 1-0 and provisionally stretch its lead to eight points Saturday. Lackluster defending allowed the Poland striker to score in the 10th minute, firing inside the far corner after Xabi Alonso and then Thiago Alcantara encountered a similar lack of resistance. With seven games remaining, Lewandowski already has one more than his previous season-best of 24 for Borussia Dortmund in 2012-13. "There are still lots of games and goals to score, I hope. The number I need for the top-scorers' trophy is not an issue for me," said Lewandowski, competing with Dortmund's Pierre-Emerick Aubameyang (22 goals) and Bayern teammate Thomas Mueller (19). With the lead in the bag, Bayern comfortably dominated the rest of the half without too much exertion. Leonardo Bittencourt had the home side's first shot on goal in the 50th, straight at Manuel Neuer. Anthony Modeste had Cologne's best chance with Neuer stranded, but David Alaba came to his goalkeeper's rescue with a crucial block. Alaba extended his Bayern contract to 2021 Friday. Neuer also saved from Bittencourt in injury time. Dortmund can restore the five-point gap with a win at Augsburg Sunday. Japan's Genki Haraguchi scored one and set up another for high-flying Hertha Berlin to beat Ingolstadt 2-1 and consolidate third place. Haraguchi shot the home side ahead in the 54th and crossed for Solomon Kalou in the 69th. Lukas Hinterseer pulled one back to make it exciting with 15 minutes remaining, but John Anthony Brooks cleared off the line to safeguard Hertha's three points. Also, Andre Schuerrle scored in injury time to salvage a 1-1 draw for Wolfsburg against Darmstadt, Hoffenheim boosted its chances of avoiding the drop with a 3-1 win at Hamburger SV and Mainz drew 1-1 at Werder Bremen. Claudio Pizarro's 12th goal of the season for Bremen, a penalty before the interval, canceled out Julian Baumgartlinger 38th-minute opener for Mainz. Baumgartlinger then gave away the penalty. Sandro Wagner's 82nd-minute strike looked like it was going to be enough for promoted Darmstadt, only for Schuerrle to score in the 93rd to spare the home side's blushes. Wolfsburg was drawn against Real Madrid in the Champions League quarterfinals Friday. Atletico stumbles Atletico Madrid stumbled in its pursuit of Barcelona for the Spanish league title after conceding two late goals to lose 2-1 at relegation-threatened Sporting Gijon Saturday. Atletico looked set to maintain its title challenge after Antoine Griezmann scored from a free kick in the 29th minute. The visitor's defense had resisted Sporting's attack until a late push produced a free kick that Antonio Sanabria blasted in with 11 minutes to play. Sporting's Carlos Castro completed the turnaround with a goal in the 89th just after he appeared to have blown the comeback when he hit the bar with the net wide open. Barcelona leads second-place Atletico by eight points before visiting fourth-place Villarreal Sunday.
