Tennis: Williams to meet Errani in Paris s-finals

PARIS (Reuters) - Serena Williams extended her winning streak to 29 matches when she beat Russian Svetlana Kuznetsova 6-1, 3-6, 6-3 in the quarter-finals, to continue her run towards a second French Open tennis title on Tuesday.

The world No.1, who won her only Roland Garros crown in 2002, came back from a break down in the decider and played some beautiful tennis to set up a semi-final meeting with Italian fifth seed Sara Errani.

After strolling through the opening set, the 15-time Grand Slam singles champion came up against a streak of forehand winners from Kuznetsova, the 2009 French Open winner.

The American fell 0-2 behind in the third before winning five games in a row, wrapping up victory with a forehand volley after nearly two hours.

Earlier, Errani proved her run to last year's French Open final was no fluke as she toppled Polish fourth seed Agnieszka Radwanska 6-4 7-6 (8-6).

In a scrappy match where the second set alone featured eight breaks of serve, it was the diminutive Italian who finally raised her arms in celebration after her opponent whipped a backhand into the tramlines.

Errani's prolific work ethic this year - her 81 matches are almost double that of anyone else in the top 10 - paid off as she flummoxed Radwanska with an array of ferocious forehands, delightful drop shots and luscious lobs, to secure her first-ever win over a top five player.
