Schiavone, the 2010 French Open champion now ranked 48th, is through to her first final of the year. She'll aim for her sixth title and first since winning the Strasbourg Open last May.
She leads Dominguez Lino 3-1 in career meetings. The 32-year-old veterans first played each other 15 years ago on clay at Spoleto, Italy, where the Spaniard beat Schiavone for her only win.
Dominguez Lino goes for her third title and first since winning two years ago in Bogota, Colombia.
