Since the Trade, Lopez has hit .284/.385/.432 with 2 HR in 81 AB. Still not on par with last year (except for the BB rate), but still good numbers.
And about his defense:
How bad is it really? From what I could tell visually, he had at the very least average range, if not above average, and a strong, if at teams a tad erratic, arm. What really was wrong with his defense?
