Link: Alvarez and Tabata to Get the Call in 2010?

In a chat with readers, Dejan Kovacevic of the Pittsburgh Post-Gazette discusses the timetables of some of the Pirates top prospects.  At the top of any Pirate prospect discussion has to be Pedro Alvarez and Jose Tabata, both of whom Kovacevic says will likely be called up at some point in 2010, but implies that it is likely to be after the Pirates are comfortable that neither player's arbitration timetable will be pushed up by the promotion.
