Over/under isn't typically played with tennis but leave it to Ladbrokes to find a betting angle.

Ladbrokes are currently running a great prop for tennis betting that involves using your knowledge of a player to guess where he will be ranked at year's end (for 2010). 

You've played over/under with football, baseball, basketball, and hockey scores but the game isn't usually offered in tennis.  At the present time however you can play over/under with the ATP tour - not with any scores but with a player's tennis ranking.

Do you think you know the direction one of your favorite stars is heading in?  Check with Ladbrokes to see if that player has a betting line and make your picks on those lines.  Results will be decided by the ranking system and the results at the end of the 2010 ATP season.
