Sharapova, who reached her first quarter-final since returning from her drugs ban in Madrid last week, outlasted the Australian 7-5 3-6 6-2 in a match lasting two and a half hours.
Sharapova, who is chasing a fourth career Italian Open title, told wtatour.com: "This tournament has been special in my career, and brought me some great matches.
"I'm a little bit more relieved this year, and just playing and not worrying about anything else, which is nice."
