Yesterday, in his Minor League Update at BP, Kevin Goldstein had the following to say about C Francisco Pena:
The son of Tony Pena, who won four Gold Gloves in the 1980s, Pena was a big-budget signing out of the Dominican three years ago, but he spent his first two years doing little offensively in the Low-A Sally League. Still just 19, his overall batting line is still a poor .237/.281/.369, but he's as hot as he has ever been as a pro of late, going 8-for-16 in his last three games with a home run in each one. A plus defender, he's still got a chance to turn into a solid big league backstop.
Emphasis mine. Pena has the tools and it's now noteworthy that KG is getting reports out of Florida that Pena has translated those tools into "plus" defensive capabilities.
