Under the Training menu there are three sections of tutorials you need to complete: Batting, Bowling, and Fielding. There are 37 tutorials in total across the 3 sections. Most of them are fairly straight forward and you should be able to finish them in a minute or two. While going for this achievement, you should unlock the Choo Choo achievement as well by simply going through all the tutorials.
A couple tips for the few tutorials that gave me some problems:
*For the Bowling tutorial where you need to appeal to the umpire by pressing up on the d-pad, you need to appeal after the batsman hits/swings at the ball. Thanks to Joel78 for clarifying this in the comments below.
*For both Fielding tutorials that involve catching, half the time the batters don't hit the ball in a way that gives you an opportunity to actually catch it, but if you keep playing you'll get the necessary catches eventually.
