Easier Homeruns
When at bat the easiest way to hit a home run is to the hold up and left buttons continue to hold these buttons after you hit the ball. This will cause the ball fly passed the left fielder. This is not guaranteed, the left fielder may still catch the ball.

An Out / Not a Hit After the game has started, throw a pitch so the hitter hits it. Then throw the ball to second base. When the player catches it move so that the other player covers the base. Move the player with the ball close to the base and press TRIANGLE and he will underhand it to the player on the base. If this is done correctly the ball will go high in the air. While the ball is in the air try to catch the ball with the outfielder before the ball catches the ground. If the outfielder catches it it's an out.

Easy Strike-Outs Get a pitcher with a good arm and a sinker. Pitch a sinker to the batter inside and down a little bit, outside of the strike zone. Once you find the right spot just keep pitching it there and you should strike the batter out in 5 pitches. Again, this is just a helpful hint, not a guarantee
