Thanks to the San Diego Union-Tribune-
That's a market the Padres have explored since last May, when they and the Cubs – frequent trade partners in recent years – considered various scenarios. The Cubs have kept tabs on Padres shortstop Khalil Greene, and the Padres have monitored Cubs center fielder Felix Pie, who lost playing time to Reed Johnson. After Edmonds went down last month, the Padres considered center fielders such as Jeremy Reed, who was optioned to Triple-A by the Mariners, and Tony Gwynn Jr. of the Brewers.
I doubt the Cubs would give up Pie straight up for Greene, let alone in a package for him. Although I do like the idea of getting Greene because of his defense and decent bat. He has never fair well at Petco and would benefit hitting in a hitter friendly division. I think if we offered a guy like Fuld, Colvin, or Eric Patterson in part of a package would seem fair. Either way the Cubs adding Greene would really benefit them, even though Theriot and Cedeno have been doing a decent job.
