I can't help but draw some parallels between the current Andrew Lambo situation and the Jeff Clement experiment at first base a few years ago. In both situations you've got a guy learning first base in the majors. Lambo has more experience at the position than Clement, which gives him an edge, but not enough experience to make you comfortable with his defense.
In each case the Pirates couldn't play the player at his original position. Clement could no longer play behind the plate, and the Pirates have no need for Lambo in right field, since they'll open the season with Travis Snider/Jose Tabata, and will eventually move to Gregory Polanco for the long-term.
The appeal for each player came with their bat, and especially their power potential. Lambo is coming off a season where he hit 33 home runs between Double-A, Triple-A, and the majors. That's actually better than Clement, who had 21 home runs in Triple-A in 2009, with 14 of those coming in the PCL.
