Lets Call 50

I saw this puzzle on the site http://www.crackpuzzles.com/

Suppose two players are playing a game where we call integers. The first person who calls 50 wins. The rules are that the first person calls a number between 1 and 10. After that any new number that is called must exceed the last number by at least one and no more than by 10. For example: If the last number called is 15, then the next number that is called must be between 16-25.
I give you the first mover advantage, devise a strategy to win.
