2009 WIMBLEDON FINAL
Serena ended Venus' two-year reign as Wimbledon champion with a 7-6 (7-3), 6-2 victory that secured her a third All England Club crown. It was the fourth time the sisters had met in a Wimbledon final, with Serena, who now held the Wimbledon, Australian and US Open crowns, winning three of those showpiece showdowns. The 27-year-old's 11th career win over her sibling saw her regain the Wimbledon title she won in 2002 and 2003, and shattered five-time champion Venus' hopes of lifting the trophy for a third successive year.
2009 DUBAI CHAMPIONSHIP SEMI-FINAL
Venus beat top-ranked Serena 6-1, 2-6, 7-6 (7-3) to take a 10-9 lead in the sibling rivalry. It was Venus' fifth win in their last seven meetings but Serena earned plenty of plaudits as well, for defying the pain of a knee injury that had forced her to retire from a tournament the previous week. It was only the second time a set had gone all the way to a tie-break in their 19 career meetings up to that point.
2008 US OPEN QUARTER-FINAL
Down 3-5 in the first set and 2-5 in the second, Serena refused to let Venus cross the finish line in a marathon New York encounter. Serena saved two set points in the first set and eight in the second, all in the two tie-breakers that she eventually won to secure a 7-6 (8-6), 7-6 (9-7) victory in front of a capacity crowd, including celebrities Diana Ross, Spike Lee and Robert Redford, at Arthur Ashe Stadium.
2008 WIMBLEDON FINAL
Venus clinched her fifth Wimbledon title with a 7-5, 6-4 win in one of the few really high-quality clashes between the pair at the All England Club. Venus, 28, defied blustery conditions to become one of only four players to lift the trophy five times or more in the modern era. She sealed the historic victory when Serena fired a backhand wide, but her celebrations were muted as she hugged her sister at the net.
2003 AUSTRALIAN OPEN FINAL
One of the most dramatic finals between the sisters came in the heat of Melbourne, when Serena clinched the last Grand Slam title to elude her with a tension-filled 7-6 (7-4), 3-6, 6-4 victory. It was only the sixth time a woman had held all four of Grand Slams at the same time, and the first since Steffi Graf in 1994. Venus made unwanted history as the first woman to lose four straight Grand Slam finals.
