Top seed Caroline Wozniacki powered into the final of the Malaysian Open on Saturday with a dominant 6-2 6-2 win over Hsieh Su-Wei.

Wozniacki needed just an hour and 17 minutes to see off wildcard Hsieh, although it was not all plain sailing for the world number five.

The Dane cruised into a 3-0 lead in the first, only for Hsieh to briefly put matters back on serve at 3-2 before Wozniacki won three straight games to take the set.

Hsieh threatened a comeback by breaking Wozniacki immediately at the start of the second.

But Wozniacki instantly broke back and her quality then shone through as she claimed five of the next six games to stay on course for a 23rd WTA singles title.

After the match Wozniacki posted on Twitter: "In to my second finals of the year! Thank you for the support everyone! Finals tomorrow 6pm!!"

And the former world number one will be expected to make similarly short work of Alexandra Dulgheru in the final.

Dulgheru will head into the showpiece having come through a gruelling clash with fourth seed Jarmila Gajdosova 5-7 7-5 7-6 (7-4).

The Romanian won the tie-break at the end of a deciding set in which Gajdosova had spurned 14 break-point opportunities to triumph after three hours and 14 minutes.
