It's a Friday, I come out of a three-hour meeting and suddenly a thought zapped into my mind: Jeff Kent and Jose Vizcaino were traded together twice, once from the Mets to the Indians, and then from the Indians to the Giants. So that got me thinking--which other pairing has been traded twice together? Any pairs that have been traded together three or more times? Andy from High Heat Stats is asking his readers too, but Bluebird Banterers: can you think of any?
