He played stellar defense for the Sox in 2006. And right now he is batting a hell of a lot better than Nick Green. He'd likely cost the Sox a lower-tier farm player or the ever-popular "player to be named later". To me, this is a no-brainer. But then again, I am not running the team.
Update Less Than Five Minutes Later: Alex Gonzalez has rejoined the Red Sox. Chris Woodward, we hardly knew ye.
Yet Another Update: According to WEEI, through a report on Boston.com, the Sox have sent Single A shortstop Kris Negron to the Reds in exchange for Gonzalez.
Negron is surplus to the Sox, as SS is a position the Sox have two or three prospects in that project much higher than Negron. That said, the kid is a speed demon and if he could ever hit with consistency, he could have a future.
