Getting better players
When you are in a season or a franchise, get a player from your lineup, but not as good as your better players. Spend time just trying to find better players than you are using, like Carlos Lee, Normar, Sheffield, Gordon, Lowe , Nathan. Get one of them and try to find one of the best player on a opposing team's line up. Trade your new player for him, such as Martinez.

Inside-the-park homerun
Hit the ball through the infield then you keep running towards second base until the fielder gets the ball. Then, run about halfway back to first base. You will see the first basemen get the ball. Then, run back to second base. You will make it without a throw if he does go back to first. Keep trying and you will eventually reach second base. Then, run to third base. The third basemen will get the ball halfway, then have your player run back to second base. If it does not work, keep repeating. Do the same thing for home plate. If you do this in season mode it will
register as a real home run. This is useful when trying to pass the homerun record. Note: Press L1 to run forward and R1 to run back.
