London, England (SportsNetwork.com) - World No. 7 Tomas Berdych was an easy round-robin winner Wednesday at the season-ending $6 million ATP World Tour Finals in London.
This week's sixth seed blew past eighth-seeded U.S. Open champion Marin Cilic 6-3, 6-1 in 75 minutes at The O2. The Czech Berdych tallied four service breaks, compared to zero for the Croatian star Cilic.
Berdych is now 6-4 lifetime against Cilic, including 2-2 this season.
Day 4's Group A night session match will pit world No. 1 Wimbledon champion Novak Djokovic against third-seeded Australian Open titlist Stan Wawrinka.
Surprisingly, all seven matches so far this week have ended in straight sets.
Group A features the two-time reigning and three-time overall Tour Finals champion Djokovic (1-0), Wawrinka (1-0), Berdych (1-1) and Cilic (0-2).
Djokovic topped Rafael Nadal in last year's finale in London. The 27-year- old Serbian star is two wins away from clinching the year-end No. 1 ranking for the third time in four years.
This week's four-player Group B boasts second-seeded Wimbledon champion Roger Federer (2-0), fourth-seeded U.S. Open runner-up Kei Nishikori (1-1), fifth- seeded British favorite Andy Murray (1-1) and seventh-seeded Canadian slugger Milos Raonic (0-2).
On Thursday, the 17-time Grand Slam king Federer will battle Murray and Nishikori will take on Raonic in some more round-robin play. Federer and Murray have split 22 career matchups, but Federer is 2-0 this year and 3-0 versus Murray all-time at the Finals.
Federer, who is making a record 13th consecutive appearance at the Tour Finals and still has an outside chance of capturing the year-end top ranking, holds the record for the most titles at this exclusive event with six.
If Federer were to qualify for his 12th career Finals semifinal, it would tie the record set by Ivan Lendl. The 33-year-old Swiss icon would also be the oldest player to advance to the last four since 2003 runner-up Andre Agassi.
Nishikori, Raonic and Cilic are making their Tour Finals debuts this week.
Round-robin action will be staged here through Friday, followed by the semifinals on Saturday and lucrative final on Sunday.
