His been good defensively so far this year, but statistically he's a league average CF at best.
He can't get on base to utilize the one offensive advantage he has over Pena.
That being said, he plays the game very hard and clearly wants to succeed, I just think him getting consistent ABs right now is hurting the team. They aren't putting the best team out there that they can, and that's what I take issue with.
I just found that picture to be funny.
