I feel like this news came out a few weeks ago (and that I whiffed on writing about it then), but since it's in today's paper, maybe not:

The Phillies will send eight players to the Arizona Fall League to play for the Mesa Solar Sox: righthanders Joe Bisenius, Andrew Carpenter and Pat Overholt; lefthander Sergio Escalona; catcher Lou Marson; infielder Jason Donald; and outfielders Quintin Berry and Jeremy Slayden.

It's an interesting group. Marson and Donald you probably know about: they're generally regarded as the top two position prospects in the system, and just played pivotal roles in the U.S. Olympic baseball team's bronze medal win. Bisenius, who turns 26 next month, has gotten off-track in the last two years after looking like a possible closer-to-be through 2006, but the team still seems to believe he has a big-league future. Carpenter's season got off to a dismal start; he showed up at camp overweight and was pounded at Reading for two months before being sent back to Clearwater. Successful again there, he's been much better since a return promotion to AA. Escalona I know very little about, but his strikeout numbers are intriguing.

Berry, a speedster without any power, and Slayden, a Greg Dobbs-type hitter with perhaps a little more pop, are both on the old side for prospects and project as extra outfielders in the majors. It's possible that the Phillies are thinking that one or both might gain some trade value with strong showings in the desert.
