The Yankees have signed Dominican center fielder Eladio Moronta, according to LoHud's Sam Borden. According to Borden, Moronta was previously suspended by MLB for lying about his age.

Mike Axisa over at River Ave Blues goes into a little more detail:

The Yanks signed Dominican outfielder Eladio Moronta, a soon to be 21-year-old righty with “plus-plus speed, a strong arm and projectable power.” MLB had suspended Moronta earlier this year for lying about his age, and prior to the suspension it was believed he would receive a seven figure bonus. Instead, he settled for $570,000. One scout dropped a Raul Mondesi comp on him, which would be amazing. 30-30 guys don’t grow on trees.

Just judging from that description, I'd say it couldn't hurt to have this guy around. I won't pretend to know any more about him than the information Sam and Mike gave, though.
