Pearce could return soon, which might lessen the need some for a position player off the bench.
Neal Huntington was on MLB Network Radio, and told Jim Bowden that the team is looking to add a starting pitcher, a bullpen arm, and a position player. That's not really ground breaking, as it covers pretty much every possibility.
The starting pitcher might be a surprise with the way the rotation has been performing. However, the Pirates don't really have much depth. Ross Ohlendorf is returning from an injury, and probably won't return until early August. Brad Lincoln looked good in his one start this year, but is unproven. Justin Wilson has put up good numbers, despite some control issues, but has yet to make a major league start. The Pirates have been lucky to avoid the injury bug with their starting rotation. At the same time, that's led to a situation where most of their starters are nearing their 2010 inning totals, which could lead to some struggles down the stretch.
