Federer adds Halle to schedule

Berlin - Roger Federer will warm up for this year's Wimbledon by playing at Germany's Halle ATP tournament from June 7 until June 12, it was announced on Thursday.

The 29-year-old Swiss star, who has won a record 16 Grand Slam titles including six Wimbledon crowns, traditionally plays at Halle's event to prepare for the fortnight-long championships at SW19.

Federer has won the Halle tournament five times and Australia's Lleyton Hewett, who beat him 3-6, 7-6 (7/4), 6-4 in the 2010 final, has also said he will play the grass-court tournament.

With a world ranking of second in the world, Federer is the top player to sign up so far for Halle with fellow top-10 players Tomas Berdych, of the Czech Republic, and Sweden's Robin Soderling, also due to attend.
