I try not to think much about trade rumors unless they're credible, but mlb.com says this one is credible:
Of the dozens of trade scenarios fans have submitted to me in the past few weeks, Mark, I would say yours is the most plausible. In fact, this deal was being discussed, at least internally, by the Pirates prior to the trading deadline.
Ed Eagle isn't a good writer, but I see no reason not to believe him on this one. I wonder if Wells for Pena was ever offered by the Reds? If it was, the Pirates would have been crazy not to take it. If Dave Littlefield can get Pena for Wells now, well, that would be even more one-sided and helpful than the trade that brought Wells to Pittsburgh in the first place.
Elsewhere at mlb.com, Jim Tracy will answer questions from fans tomorrow (Tuesday) at 4:00 PM EST.
