Maria Sharapova’s belated return to the Australian Open ended swiftly Monday when the former world number one was knocked out just hours after the first grand slam of 2010 began.

Sharapova, making her first appearance at Melbourne Park since winning the championship two years ago, lost to fellow Russian Maria Kirilenko 7-6 3-6 6-4 on the Rod Laver Arena.

Unable to defend her title last year because of a shoulder injury, Sharapova was a shadow of the player who stormed to the 2008 title without dropping a single set, contributing to her own defeat with 66 unforced errors and 11 double faults.
