If you want to get this over and done with quickly, you can play with two controllers.
Make sure you're batting first, then with your second controller go into the
Settings and turn "
Assisted Fielding" to "
Manual" (it's listed in "
General Settings").
Then simply bowl and hit a shot. The fielders will just stand still so you can mash

and rack up the runs. Once you think you've got enough, just get the ball with your second controller.
Note: There doesn't seem to be a limit of how many runs you can score from one ball this way (I managed 212 in one go when testing to see if it counted).
