Can domain other than .com appear in first page result?

Hi all, Most of the sites get first page result are either .com or .net and rarely any other, unless they are already popular or people specifically searched the domain name.

I understand the problem of maintaining a .com domain with not-so-legal stuff, but what are the chances of .ws or .sx ..etc get first page result, if i'm starting from the bottom? (assuming i abide to google's rule)
