This year he's hitting lefties reasonably well. Over the course of his career, he hits them like crap, though. Neifi has a .275/.299/.429 line against lefties in his career. Is that better than Todd or Ronny vs lefties? Perhaps, but I really don't think it's enough to justify the roster space he takes up, and certainly not at the price he's being paid. For comparison, Todd vs lefties in his career: .259/.311/.370
