ROTTERDAM, Netherlands (AP) Third-seeded Tomas Berdych of the Czech Republic beat Andreas Seppi of Italy for the fifth time in a row 6-3, 6-3 to open his account at the ABN Amro tournament on Monday.
Berdych, coming off a semifinal run at the Australian Open and Davis Cup win over the Netherlands, didn't face a break-point.
A semifinalist two years ago here, he will play the winner of an all-French faceoff between Gilles Simon and Nicolas Mahut.
Fifth-seeded Jo-Wilfried Tsonga played Florian Mayer of Germany late Monday.
Defending champion Juan Martin del Potro and Wimbledon champ Andy Murray - a last-minute wild card addition as second seed - will appear on Wednesday.
