This achievement usually needs to be boosted, as nobody seems to play this online anymore. Go the chat room here or check out this game's boost list.
This can be done in either a Player Match or Ranked Match.
What the achievement means when is says "10 versus zones", it means complete areas. For instance, finishing Emerald Hill Zone Act 1 first will not count as a win, but finishing Emerald Hill Zone Act 1 & 2 in first place will count as a win.
Basically, complete 2 and a half sessions of a LIVE match in first place, and the achievement will be yours.

Good luck. =)
