The Pirates are taking a "very, very careful" approach to the trade deadline, rival officials tell ESPN.com's Buster Olney (Twitter link). There are many indications that the Pirates aren't trading major assets this month.
The 51-45 Pirates are tied for first place atop the National League Central. There's minimal room for error as the Cardinals and Reds are within four games of the division leading Brewers and Pirates. Pittsburgh has checked in on outfielders, including Carlos Beltran, and relievers in anticipation of the trade deadline.
Earlier in the week, Ken Rosenthal of FOX Sports reported that some rival GMs believe Pirates GM Neal Huntington over-values his prospects. The Pirates' first move of the summer saw them sign Jason Grilli in a deal that didn't cost Pittsburgh anything but cash and a roster spot.
