Top seed Rainer Schuettler [ Images ] took revenge by beating Swede Robin Soderling [ Images ] 6-4, 7-6 in the first round of the Munich Open on Tuesday.

Schuettler, a losing finalist in the Monte Carlo Masters on Sunday, was made to work by an opponent who beat him in the Australian Open [ Images ] first round in January.

The German, who won a close tiebreak 7-5 in the second set to seal victory, next meets his compatriot Tommy Haas [ Images ].

Wild card Haas had earlier delighted the home fans by crushing Czech Bohdan Ulihrach 6-3, 6-2.

Haas, who missed the whole of last season with a shoulder injury, put his injury woes behind him by stunning American Andy Roddick [ Images ] in the Houston final this month.

Thailand's Paradorn Srichaphan [ Images ], seeded second but not a claycourt specialist, made an early exit, beaten 6-3, 6-2 by Belgian baseliner Oliver Rochus.

Goran Ivanisevic, the 2001 Wimbledon [ Images ] champion, lost in straight sets to unheralded German Alexander Waske in his first match in the Munich tournament.

Croatian Ivanisevic is struggling after a string of injury problems and has won just two matches this year.

Qualifier Waske won 6-4, 7-6 and will next meet American Vince Spadea, the fifth seed, who moved past German qualifier Dieter Kindlmann 6-4, 6-2.
