Easy Homers
Go to the Main Menu then go to Rosters and create a player with the name "Erik Kiss" . He will hit a ton of homers. Also for some more broken bats name a player Keegn Patersn, Jacob Patersn, or Ziggy Patersn.

Fenway Homeruns
Use your big hitter in Fenway and hold the Left Analog stick diagonal toward the green monster. Inside or hot spot pitches should go over the wall.
Trade Hint
In rookie mode the computer will take almost all trades in season mode. Trade your non used players for superstars on other teams to make a super team!
Strikeout Hint
If you get two strikes on a batter make your next pitch a low inside or a slider. This is highly effective for getting the strikeout.
Right Handed Batter Hint
Point the Left Analog stick toward Right field to increase your chance of a homer.
Strike Out Hint
To get more strikeouts in a game you first have to pick a corner any corner. Then, get the baseball as tightly to the line as possible. Next. if your pitcher has a 4-seam or 2-seam fastball, sinker, slider, or a splitter you can use that. Finally, pitch like that and 80% of the time you will strike th batter out.
Vlad Guerrero
When up in the count 3-0 with Vlad, the pitch will be high and inside 95% of the time. I hit 5 homeruns in a game with Vlad.
Sucker The Padres
When playing in the franchise mode, the best way to improve your team is to trade for Oliver Perez of the San Diego Padres. You can trade a much less valuble player to get Perez, and he will be well worth it. Every franchise I've done I've got him for nothin and he's won multiple Cy Young Awards, never having an ERA over 3, plus he's in his early 20's. If you're gonna make any trades make it this one.
Cheat to Win
One way to cheat the system, especially in the playoffs, is to save your game, then configure your lineup and sim the results. If you lose, don't save. Reset the game and reconfigure the lineup based on their previous performance against that same pitcher. When you win, save the game again. Repeat to never experience defeat. It's the fastest (cheapest) way to win a World Series.
