Bernard Tomic's rapid rise into the top 50 at the tender age of 19 has created a tidal wave of expectation in Australia ahead of the year's first grand slam,but the rangy Gold Coast native is merely pleased he may have finally reached his full height.Since grabbing the world's attention with his stunning quarter-final run at Wimbledon as an 18-year old qualifier,Tomic's ranking has soared to 37 making him far and away Australia's greatest hope in the men's draw at Melbourne Park.
