Either that or that is the best they can do. His defense is the only thing that is carrying him. His bat is horrid. Drop in slugging, drop in walk rate, increase in strikeouts. He's basically Rick Ankiel.
He is Don Lock: fine CF; enough homers to give fans some hope; a million K's; mediocre average. Maybe Espinosa is good enough, and certainly he fields well enough at 2B and SS to carry on the team. I'm not yet convinced he ought to start at 2B. (In the Don Lock comparison, Unser was an improvement.)
