Subject: How does friction stop a ball from rotating while also slowing it down?

When a ball first begins motion across a surface, it is obvious that it is a 
frictional force in the direction opposite the motion that causes the ball to 
roll instead of slide. When the ball begins to slow down, there must be a 
frictional force acting in the direction opposite the balls motion, but it 
would also appear that this force would make the ball roll faster. Since there 
can't be two frictional forces acting on the ball, what is it that causes the 
ball to be able to slow down and stop rolling at the same time?
