The Yankees used to think Jorge Mateo was their future shortstop and lead off hitter. His speed numbers are off the charts, and he is too fast what Aaron Judge is to power. But Mateo is trying to be all he can be, and that might be the end of Mateo.
When Mateo came into the Yankees organization, he flashed his primary weapon: speed. He played only 14 games in 2012 and stole four bases; he also worked 12 walks. A small sample size to be certain but it starts the story well. If we multiply his games by 10 to project his skills, it comes out to 120 walks and 40 stolen bases in 140 games.
