Marte has never been an extremely highly regarded prospect while with the Mets, but he has been worth note and is only 21-years-old.
After signing him for a $550,000 bonus out of the Dominican Republic in 2007, the Mets were quite excited about Marte's first stwteside season in 2008 when, as a 17-year-old, he hit .325/.398/.532 in 44 games in the Gulf Coast League. His power was evident, and that power potential was what got him signed in the first place.
What was not evident, at that point, was his inability to lay off of pitches out of the strike zone, and just how much that would limit his ability to use his power.
Since that brief show of success, Marte has never hit double-digit home runs, has never posted a slugging percentage above .401, and only once posted an OPS over .700.
On the positive side, his walk rate of 8.4 percent in 2012 was the highest of his career and his strikeout rate of 14.8 percent in 2012 was his lowest, but he still hit just .251/.322/.356 in Double-A.
But the power that was once evident has never developed, and while he has gotten better defensively at third base, it's not enough to carry him if he doesn't hit.
Marte needs another shot at Double-A and he's still young, so the progress he's made gives his new team some hope that he can yet become a productive major leaguer in some capacity, but the power must develop and it must do so soon.
