Ok, this may be a stretch and may be a meaningless way to think of things... but lets see how it works. 

The general thought here is to see who is to blame for a loss or who deserves credit for a.  Not player wise, but pitching or offense wise. 

Rules
Any game in which the Astros lose when giving up 4 runs or less will be considered a loss caused by the offense.  Any loss in which the Astros give up 5 runs or more, will be considered a loss caused by the pitching staff. 

Same for offense; any game won when runs scored were 5 or more will be considered a win by the offense.  A game won when runs scored were 4 or less, will be considered a win for the offense. 

If the Astros score more than 4 runs and give up less than 4 runs, both the offense and pitching will get a point. 

Losses will count as a minus in that column and wins will count as a plus.  At the end of the season(if this lasts that long), whoever has the higher score, will be the side of the ball who should get credit for the most amount of wins.  Make sense?  Good.

In the event of an extra innings game... the score after 9 innings will be used to determine who gets credit for the win or the loss.  For example, if after 9 innings, the score is 4-4, then if the Astros win, the pitching will get credit for the win.  If the score is 5-5, then if the Astros win, the offense will get credit for the win.  Make sense?  Good!

** If Runs for >=5 and runs against <=4, there will be no credit given to the 1st 2 wins boxes, only the 3rd that has both... if that makes sense...
