Go to "Created Players" and make one for each position. Make sure you set their stats to the maximum. Then, add all of them to the same team (for example, Kansas City because they are the worst). Save the roster so that you can upload them whenever desired. Start a franchise with the team you have enhanced. Simulate the entire season including the World Series for easy tokens. The amount of tokens you get ranges from 4,500 to 6,000. If you run out of tokens, re-upload the enhanced team and simulate another season.
Play a game in Exhibition mode with two controllers and defeat your opponent without them getting a hit or a walk. If the winning side is using a profile, that profile will be credited with a perfect game. This is also an easy way to earn tokens.
You can edit any player and their abilities, and not just the way they look. Sign a desired minor leaguer to the maximum term (seven years) at the lowest amount, even though they may get upset later in their career. Then, change their name, abilities, position, etc. This also works for changing other major league players. For example, you can change Joe Young on the Giants to Barry Bonds by editing everything except his appearance. By doing this, you can sign an entire team. Note: You can only re-negotiate contracts at one year to seven year contracts at about $1 million each or less, then make them perfect. When you are finding a player to make your own, look for one year contracts.
On the Oakland A's default roster, notice that they have Milton Bradley, Antonio Perez, and Andre Ethier on the team. This is incorrect because the Dodgers traded Bradley and Perez to Oakland in exchange for Ethier. Therefore, all three players cannot be on the same team.
