Ian Snell won't pitch in the Arizona Fall League; Mike Connolly will take his place.
Two articles on this issue, the John Perrotto article above and this one from the Royals' team website, offer conflicting explanations for Snell's withdrawal. Here's Perrotto's:
The decision was not related to fatigue as reported on the league's official Web site. Snell logged 154 innings this season between the Pirates and Class AAA Indianapolis, and Littlefield wanted Snell to continue pitching.
Hmm. Here's Major League Baseball's passive-voiced explanation:
Ian Snell is probably a jerk, and I can only speculate as to what's going on here, but it reminds me of this story, summarized by Wilbur Miller:
Why was Snell not quoted in either of these articles? I don't know what happened, but the Pirates' past suggests that this is part of a negative-publicity campaign against Snell. They don't like him, for whatever reason (be it his stuff or his personality), and my guess is that they're going to use every excuse to bury him in the bullpen or in the minors, just like they buried J.J. Davis. It's not hard to do if you can fling dirt freely in the media - already, the residents at one Pirate message board are declaring that they want Snell out of the organization.
