MELBOURNE — Maria Sharapova finished her first match of the year in 55 minutes Monday, cruising to a 6-0, 6-0 win over Olga Puchkova to start proceedings on center court at the Australian Open without showing any signs of trouble with her sore right shoulder.

The No. 2-ranked Sharapova, who lost the final to Victoria Azarenka here last year before going on to win the French Open, faced only two break points in the match and she saved both of those in the first game.
