DUBAI, March 4: Serena Williams quit her Dubai Open semi-final with an arm injury on Friday while trailing Serbia's Jelena Jankovic 6-0 4-3.

The second-seeded American, who also defaulted her quarterfinal match at the last event she played in Paris earlier this month, pulled out after a discussion with a courtside trainer.

Jankovic will play top seed Lindsay Davenport in the final of the $1 million event after Davenport overcame a stomach upset and a strong challenge from Switzerland's Patty Schnyder to win 4-6 7-5 6-1 earlier in the day.

Seed Davenport was ultimately too strong for her opponent in the other semi-final although initially Schnyder took advantage of a lethargic performance in the first set.

SEMIFINALS RESULTS: Lindsay Davenport bt Patty Schnyder 4-6, 7-5, 6-1; Jelena Jankovic bt Serena Williams 6-0, 4-3 retired. -Agencies
