The victory will give Ferrero a boost. He won his first-round match on Tuesday after opening-round losses in the Australian Open and another tournament in New Zealand.
Andreev, 26, reached his first quarterfinals of an ATP event since August. He won his two break points in the third set to close out the match in 2 hours, 33 minutes.
Andreev, who pushed top-ranked Roger Federer to four sets before losing in the first round of the Australian Open, next faces Cuevas.
