A little scoring help

SPORTING GOODS

No need to comment on the Sox lost weekend; they are what they are right now. But I have a scoring question for whoever can answer:

Can someone explain to me how David Wells is only charged with one unearned run in this inning?

- D. Hollins singled to shallow left
- C. Crawford safe at first on first baseman D. Ortiz's fielding error, D. Hollins to second
- J. Cantu singled to left, D. Hollins scored, C. Crawford out at third
- T. Lee fouled out to catcher
- J. Gomes walked, J. Cantu to second
- G. Norton singled to center, J. Cantu scored, J. Gomes to second
- B.J. Upton singled to center, J. Gomes scored, G. Norton to second
- J. Paul singled to left, G. Norton scored, B.J. Upton to third
- B. Zobrist grounded into fielder's choice, J. Paul out at second

It seems to me that Crawford reaching on an error should have been out number one. So then him getting out while trying to reach 3B on a single shouldn't be counted as "potential out number two." Crawford can't be counted out twice, can he? Lee's foulout then should be "potential out number two" (as it is also the actual real out number two), so Wells then crapping the bed should all be earned.

I know it doesn't really matter, but David Wells shouldn't get any suggestion that he did anything less than suck on Saturday night.
