You can attempt to do this in a regular game. Try to lead off as much as possible and use a speedy runner. It's much easier if the pitch happens not to be a fastball (if you somehow know what's coming). Weak arm catchers are easier to steal on also. Some pitchers have longer windups (Like Lincecum of the Giants).
Otherwise you can use these tips.
1) Play with a friend online. Have him intentionally walk a guy, then you steal the bases. Don't forget you can steal home, just have him throw the ball to a different base when running.
3) Increase your sliders in the in-game menu, specifically speed and hitting so that you get on base in the first place. Then steal away.(Did not get it this way, can not completely verify)

No need to read or do all that stuff from the other solutions this way can get you 11 or more playing a regular game.

Play AGAINST the Brewers make the starting pitcher D.Bush as he takes 50 years to throw the ball. Then just pick your team or a team with good speed (I play as the Phillies and was stealing bases with Ryan Howard against this guy) take how ever many steps off the bag he'll let you get when he starts to throw the ball just run to second and stay there. With a fast runner you should be able to take third base as well.

You should have no problem with this I stole 3-4 times on fastballs with slow runners....

Hope this helps
