Osaka, Osaka Prefecture, Japan, 7 October 2014 |

Sam Stosur has kicked off her title defence at the Japan Women’s Open in style with a straight-sets win over Japan’s Misa Eguchi.

In the second round she will face fellow Australian Jarmila Gajdosova, who earlier on Tuesday overcame Japanese lucky loser Miharu Imanishi 6-4 6-0.

Gajdosova served six aces en route to the the 59-minute victory, and takes a 2-0 head-to-head record into her match against Stosur.

The world No.68 has won both their previous meetings – at Eastbourne in 2006 and Brisbane in 2011 – in straight sets.

Stosur, meanwhile, won 6-4 7-5 in one hour and 31 minutes, surviving a tough fight from the 127th-ranked Eguchi.

Scores were level throughout the first set until the top seed snared a break in the 10th game to pocket the opening set.

Stosur immediately went down a break in the second set, but from 2-4 reeled off three straight games to turn the match back in her favour.

With Eguchi serving at 5-6, the Japanese player raced to a 40-15 lead and looked set to send the set to a tiebreak.

But Stosur held firm, recovering to break serve and seal victory.

She finished the match with an impressive 83 per cent success rate on first serve points.
