In his first full season with the Tigers, Jackson has played in 51 games and is batting .341 with an OBP of .387. Even more impressive than his offensive statistics are the flashes of greatness he's shown in center field. Most recently when he made an over-the-shoulder grab to keep Armando Galarraga's perfect game intact in the ninth inning.
Leyland said there is no limit to what Jackson can achieve if he continues working to get better.
"I think the key is going to be if he continues his work habits over his career, then he'll be a great center fielder," Leyland said. "If he's satisfied with where he's at and doesn't continue to work, he won't reach the potential that he has.
"He has the potential to be a tremendous center fielder and most of that is because of his concentration. If he maintains that, he will play second fiddle to nobody."
