MUNICH (AP) - Federico Delbonis of Argentina beat two-time champion Nikolay Davydenko 6-2, 7-6 (4) Monday to reach the second round of the BMW Open.

The 44th-ranked Delbonis never faced a break point and broke the Russian twice in the first set to take control of the match.

German wild-card entry Dustin Brown also advanced by ousting big-serving Ivo Karlovic 7-6 (4), 7-6 (5) in a match that saw no breaks of serve and only one break point for each player.

Brown will play top-seeded Fabio Fognini of Italy in the second round.

In Monday's other matches, Alejandro Falla of Colombia defeated Jarkko Nieminen of Finland 6-2, 6-1, and Marinko Matosevic of Australia advanced when Michal Przysiezny of Poland retired when leading 6-2, 5-6.
