Jen Langosch of MLB.com reports that the Pirates have recalled first baseman Jeff Clement and infielder Argenis Diaz. Langosch also said that Garrett Jones is not going anywhere.
Diaz is known as a defensively strong shortstop with no bat. I'd think Bobby Crosby is on his way out, but who wants Bobby Crosby?
Update: Apparently, the Diamondbacks want Crosby, as he and D.J. Carrasco are going to the Diamondbacks as part of the trade for catcher Chris Snyder. Even more incredibly, the Diamondbacks wanted Ryan Church, as he is part of the deal. Obviously, the Diamondbacks don't really want Church, as this trade is almost certainly about getting rid of Snyder's salary.
The Pirates will also receive an unnamed minor league player. Carrasco was a useful relief pitcher, but this trade is probably of little consequence: Clement will replace Church, Diaz will replace Crosby, and while both Clement and Diaz aren't likely to produce much offensively, neither did the guys they're replacing.
