A month into their coaching partnership Wesley Whitehouse thinks he's worked out the tweaks needed for Kiwi tennis number one Marina Erakovic.

After two and a half years together, Erakovic split from Spaniard Eduardo Nicholas last month.

South African born Whitehouse, a former Junior Wimbledon champion, says it's been about a change in Erakovic's approach rather than a change to her game.

He is trying to get her to be more aggressive.


However it hasn't been a good start with Erakovic crashing out of the first round at the WTA tournament in Seoul, losing 2-6, 7-5, 6-4 to Romanian Patricia Tig.
