Jon Heyman of SI tweets " the Pirates may still not have a manager...but hearing they're aggressive going for players early."
It's hard to guess who they're after; it's not like there's just one or two holes to stick a finger into. But if they're out this early, maybe they're looking at non-tendered JJ Hardy for short, a guy they should have grabbed last year.
Jason Bartlett and Ryan Theriot are non-tender candidates, too. The market itself is quite slim; Orlando Cabrero and Juan Uribe may be the top players. Corner outfield or first base is really barren; they may have to trade to upgrade there.
The pitching prospects are problematic; it's a thin market. They could be looking at cross your fingers and hope guys like Jeremy Bonderman, Rich Harden, Jeff Francis, Javier Vazquez, Jon Garland, Chris Young or Aaron Harang.
Expect another cattle call for the bullpen; those arms are ample and available, especially if they commit to Evan Meek and Joel Hanrahan to set up and close. The rest is easy.
