Halle, June 15:

Roger Federer kept alive his grass winning streak and captured his 55th title on Sunday with a 6-3, 6-4 win against Philipp Kohlschreiber at the Gerry Weber Open.

Federer, who sailed through the Wimbledon warmup without a dropped set, ran his record unbeaten run on grass to 59 matches. The 40th-ranked German netted a backhand after a long rally to end the match.

The top-ranked Swiss restored some confidence after one of his worst defeats — a rout in the French Open final at the hands of rival Rafael Nadal. He took just four games.

Federer, who raised his record to 10-0 in grass finals, won Halle for the fifth time. The previous four were followed by Wimbledon title three weeks later. Federer won Halle for the first time in 2003 — before going on to win his first Wimbledon title — and now has won 24 straight at the tournament, a streak dating back to that year.

In Barcelona, second-seeded Maria Kirilenko of Russia won the Torneo Barcelona on Sunday with a comfortable 6-0, 6-2 victory over Spanish wild card Maria Jose Martinez Sanchez. The title was Kirilenko’s second of the year, following her win at Estoril, Portugal, in April.

Kirilenko, who will climb to 19th in the world rankings on Monday, allowed her opponent a little respite in the second set.

In Warsaw, top-seeded Nikolay Davydenko captured his third ATP Tour title of the year, beating second-seeded Tommy Robredo 6-3, 6-3 in the final of the Warsaw Open.

Davydenko, who also won the clay-court tournament in 2006, broke the defending champion three times in the first set, while giving up his serve once. He needed just one break in the second, saving five breakpoints en route to clinching the victory.

Davydenko also won the Sony Ericsson Open in Miami and the Hypo Group International

in Poertschach, Austria, this year.
