Sandlot Sluggers

One of the first achievements you'll get in the game. Not too hard to score runs and pitch in this game, so getting wins is never that hard to come by. Always remember how many innings you set the game up for, to give you ample time to score however many runs you need.

If all else fails set the game up in the options menu for a three inning game against a second controller and just score more runs than them before the 3rd inning is over and voila!
