Sania Mirza [Images] crashed out of the Pacific Life Open on Monday, losing her singles and doubles matches.

The Indian ace lost 7-5, 4-6, 4-6 to fourth seeded Elena Dementieva in the third round of the singles, and then, pairing with Ai Sugiyama of Japan [Images], lost 6-7, 6-2, 7-6 to the second seeded pair of Zimbabwean Cara Black and Australian Rennae Stubbs in the doubles.

Against Dementieva, Sania started well in the two-hour contest, but the Russian came back strongly after losing the first set to clinch the match.

The Indian broke her higher-ranked opponent thrice in the first set to win it 7-5, but her tendency to let the momentum slip again proved her undoing as the Russian held on in the next two sets to win the match.

Sania was broken four times in the second set, which she lost 4-6.

Dementieva proved to be too good in the decider too, and despite committing six double faults, won the set 6-4.
