BERLIN, Germany (AP) — Bayern Munich opened their German Cup defence with a 4-1 win at third-division side Preussen Muenster yesterday.

Robert Lewandowski crossed for former Borussia Dortmund teammate Mario Goetze to score with a header in the 19th minute, and Thomas Mueller claimed his 100th goal in a competitive game for Bayern 10 minutes later.

David Alaba’s powerful shot in off the crossbar made it 3-0 in the 52nd, before Mueller set up substitute Claudio Pizarro to score in the 73rd.

Rogier Krohne scored an 89th-minute consolation from the penalty spot for Muenster.

There was still time for goalkeeper Daniel Masuch to save Lewandowski’s weak penalty attempt in injury time. Muenster midfielder Marc Heitmeier was sent off for bringing down the Polish striker.

Bayern defender Holger Badstuber played his first competitive game since tearing the cruciate ligament in his right knee in a draw with Dortmund on December 1, 2012.

Bayern were missing Bastian Schweinsteiger, Rafinha, Franck Ribery, Javi Martinez and Thiago Alcantara through injury.

Elsewhere, Sven Schipplock scored five in Hoffenheim’s 9-0 rout of fifth-tier side USC Paloma, Werder Bremen needed extra time to beat fourth-tier FV Illertissen 3-2, and Freiburg defeated Eintracht Trier, another fourth-tier side, 2-0.

Augsburg lost 1-0 to fourth-tier side Magdeburg for the biggest upset of the opening round, and Paderborn, promoted to the Bundesliga this season, lost 2-1 at second-division Leipzig.

Third-division side Arminia Bielefeld upset second-division SV Sandhausen 4-1, with captain Fabian Klos scoring arguably the goal of the round — a spectacular volley directly from a corner in off the crossbar.

There was another upset later, when fourth-tier Wuerzburger Kickers defeated second-division Fortuna Duesseldorf 3-2 with a deflected free-kick in extra time.

Erzgebirge Aue defeated fourth-tier Carl Zeiss Jena 1-0, 1860 Munich beat third-division Holstein Kiel 2-1 and Karlsruher SC won 3-1 at fifth-tier Neubrandenburg.

Another second-division side, Aalen, defeated fourth-tier BSV Rehden 4-3 on penalties after their game finished 1-1 after extra time.
