Yunel Escobar is a very good bat with average defense by UZR/150. To be "elite" IMHO either the bat or the glove needs to improve one more tick.
Yunel certainly has elite potential, if he can improve that last little but, but I'd say he's not there yet.
On a largely unrelated note, I've fished for a comment on this before and didn't get a bite, so I'll outright ask: does anyone see Lowrie actually abandoning hitting from the left side if that wrist continues to be an issue, and just hits from the right side, and would that actually accomplish anything meaningful?
