Baltacha, making her main draw debut at Roland Garros, must have feared a repeat of compatriot Anne Keothavong's 6-0 6-0 'double bagel' defeat by Dinara Safina at last year's French Open.
The highest-ranked woman in action on day one was second seed Maria Sharapova, who destroyed Russian compatriot Olga Puchkova 6-0 6-0 -- known as a "double bagel" -- in just 55 minutes.
The second-seeded Russian beat Japan's Misaki Doi by the double-bagel score in just 47 minutes, her second consecutive match at Melbourne Park in which her opponent failed to win a game.
