This system is so easy even a caveman can do it.

Only play on teams that won their prevous game...it's a game of streaks.

Only play on the pitcher with the better ERA...they will probably give up fewer runs.

Now that's going to give you too many games so you need to narrow it down to a select few. Choose whatever system you're comfortable with. For me, I use the pitcher's biorhythms. Frito was talking about Brad Penny's miserable performance a little while back. Had you checked out his bios, you wouldn't have been surprised that he performed poorly. He was either crossing from positive to negative or negative to positive in the 3 major bio categories that measure how he's doing physically, emotionally, and intellectually.

Had you played this system yesterday (Wednesday) you would have played Baltimore...winner, Milwaukee...winner, Cubs...winner, SD...winner, Atl...winner, CWS...winner, Min...loser, LAD...loser.
