Maria Sharapova says her long road back from shoulder surgery is a source of both perspective and motivation.
"If I'm able to win a Grand Slam after my injury it'd be my greatest achievement in my career," she told reporters in Auckland ahead of next week's event in the city.
''One of the advantages I have is the experience behind my back of knowing that I've achieved a tremendous amount and more than I ever thought I would as a child. I have that in my bag and I've come back from something that could have taken me away from the game.
"I see myself back on the court, training and getting better and I look at that as a positive. Now I have to take that onto the court and build on it little by little."
