The Pirates ended the first half of the season in first place and they plan to stay there. According to Major League sources, Pittsburgh has had preliminary trade discussions regarding two power-hitting outfielders, San Diego's Carlos Quentin and Arizona's Justin Upton. Talent evaluators from the Padres and Diamondbacks have scouted Pittsburgh's minor-league affiliates in recent days. It would seem unlikely that the Pirates would acquire both Quentin and Upton, but they clearly want to upgrade their offense. Quentin would come at a lower prospect price, because he's eligible for free agency after this season. Upton would command a larger package, since he's under contract through 2015.
