Yeah every time I clobber the other team I take my batting contact down, and turn the computer AI up. My last two games I only won by 1 run, so it's set well for me.
As for the glitch, I emailed tech support at 2Ksports and politely asked to exchange the disk. No response

I guess they don't care. It's a shame too because it really is a nice game, it just seems like they ran out of time halfway through playtesting and released it with bugs left in it.
There are many other glitches. One time I was not allowed to put in a relief pitcher, poor Marcum had to finish the game with 60% stamina. Also sometimes the announcers seem to be watching another game entirely, or think my catcher and 1st baseman traded places.
Like I said, go simulate the first season, playoff, and offseason in franchise. I'm curious to hear if you have the major glitch or not.
