ESPN writer Jayson Stark graded the National League Central on Tuesday and gave the Pirates a C+. Here is his thoughts on the Bucs offseason moves.

Pittsburgh Pirates

BIGGEST ADDITIONS: Lyle Overbay, Matt Diaz, Kevin Correia, Scott Olsen, Garrett Atkins, Joe Beimel, manager Clint Hurdle.

BIGGEST SUBTRACTIONS: Zach Duke, Lastings Milledge, Chan Ho Park, manager John Russell.

The task of making the Pirates respectable now falls to Clint Hurdle.

Look, it’s all relative. You don’t evaluate a Pirates offseason by the same standards you use to evaluate, say, a Yankees offseason, just the way a good year for Joe’s Computer Repair Shop isn’t quite the same thing as a good year for, say, Microsoft. So judged against what the Pirates were attempting to do, they did OK.

Jorge De la Rosa and Carl Pavano — both of whom they chased — would have been better rotation upgrades than Correia and Olsen. But Overbay, while he’s not exactly Adrian Gonzalez, should be an improvement over last year’s first-base hodgepodge. Diaz is a career .301/.350/.456 hitter. And there are potential bargains in their nonroster free-agent crop (Beimel, Atkins, Jose Veras, Fernando Nieve, Josh Fields).

Then there’s Hurdle, who will represent about as dramatic a change in the manager’s office, when you compare him with the soft-spoken Russell, as this team could have hired. So while it would be a monumental upset if this turns into the year the Buccos climb above Mount .500, they at least inched northward.

Grade: C+
