Compared to many of the others on our 10 To Watch list, Marc Polmans isn't a player that has had much success on tour just yet. The 21-year-old has played only two singles matches at the ATP level, and he lost each of those. Polmans is, however, a player that possesses some significant upside, and he's not somebody you're going to want to bet against succeeding.

Those that have spent time around the Australian have raved about his work ethic and eagerness to better his game. That is as important of a trait as any in a player, and it's not as if he's lacking in talent. Polmans is a well-rounded player that is capable of grinding out victories in a variety of ways. He'll only continue to get better as he gets some more experience under his belt.
