BERLIN, April 6 (Reuters) - Bayern Munich moved nine points clear in the Bundesliga with seven games to play when they recovered from an early goal and the dismissal of Mark van Bommel to win 3-1 at home to VfL Bochum on Sunday. Bayern, heading for a 21st German league title, were rocked when Mimoun Azaouagh fired the ball in from 25 metres and their situation soon got worse with Van Bommel's red card but goals from Lucio, Franck Ribery and Christian Lell saw them home. Bayern have 57 points from 27 games, followed by Schalke 04 on 48 after their 1-0 win at home to Hansa Rostock on Saturday. Hamburg SV, beaten 1-0 at resurgent VfB Stuttgart on Saturday, drop to third with 47, ahead of Werder Bremen on goal difference after their 2-1 win at Hertha Berlin. Stuttgart, last season's champions, climb to fifth on 45 points, with Bayern Leverkusen sixth on 44 after they suffered a last-gasp 2-1 defeat at Borussia Dortmund on Sunday.
