Tennis: Venus and Serena Williams both came through semi-final matches yesterday to set up an all-sister final at the $6.7 million Grand Slam Cup in Munich.

For the second time this year, the teenagers from Florida will square off for a tournament title. Elder sibling Venus, the Munich holder, won the pair's only other professional meeting for a trophy, beating her sister in March in Miami.

Serena, the 18-year-old reigning US Open holder, won a battle between the last two women to claim Grand Slam titles, ousting Wimbledon winner Lindsay Davenport 6-3, 6-4, while Venus took revenge for a defeat in a US Open semi-final three weeks ago with a 6-2, 6-7 (6/8), 9-7 victory over Swiss world number one Martina Hingis.

The women's winner on Sunday will claim $800,000 for winning three matches, $50,000 more than Serena Williams took from her Grand Slam singles title. Two men's quarter-finals were also decided at the richest payday event in the game. Briton Greg Rusedski knocked world number two Yevgeny Kafelnikov out 7-5, 7-6 (8/6) and French Open finalist Andrei Medvedev of the Ukraine knocked out Richard Krajicek of the Netherlands 7-6 (7/5), 6-4.

Golf: American Ryder Cup hero Justin Leonard was among seven players firing a five-under-par 67 on Thursday to trail leader Robert Friend by two shots after round one of the Buick Challenge in Pine Mountain, Georgia.

Leonard birdied the first three holes and gained strokes on the 11th and 15th holes as he played bogey-free golf.

Fellow Ryder Cup team-mates Steve Pate, Davis Love III and Jeff Maggert also found themselves chasing Friend. Pate carded a four-under 68, while Love shot a 70 and Maggert a one-over 73.

Friend had seven birdies without a bogey as he posted his best round of the year - he has made the cut just 16 times in 32 events.

Boxing: Felix Trinidad must make the first defence of his new World Boxing Council welterweight crown against American Derrell Coley in a bout that could come as quickly as December.

Trinidad beat Oscar de la Hoya two weeks ago to unify the WBC and International Boxing Federation crowns and his promoter, Don King, was hoping to stage a showdown with another King-backed fighter, World Boxing Association champion James Page. Instead, King has a month to make a deal with Coley's promoters or rights for the fight will be put up for bid.
