I have just compared Gomez's win-loss record vs. Span's win-loss record.  Interesting statistics!  I also will include the Twins record when the start together.  These are only the games in which they start-even if they get substituted out, I still give the win or loss to them.  

Go-Go's win-loss record when he starts:

6 wins - 4 losses

Span's win loss record:

2 wins - 4 losses

When Both start:

2 wins - 1 loss

Interesting isn't it?  So, apparently Gomez isn't going to make much difference in the number of wins or losses the club will suffer this season.

But, from where I sit, I see the same number of losses whether it is Gomez or Span so that part of the controversy is right, but, look at the number of wins.  Gomez has 4 more wins than Span does.  

As I have said before, Gomez brings an electricity to the ballclub and his defense is better than Span's, no matter how much you try to deny it.  Gomez has made running catches, bang into the wall catch, cutting balls off in the gap, diving catches, throwing runners out.  What has Span done?  A few running catches, no diving catches, no crash into the wall catch, one runner thrown out.
