Pitching for a bad team does not help determine if a relief pitcher can hold a lead. For a career on poor teams Kintler has not blown leads at a rate any worse than the better relief pitchers do in terms of blown saves to holds and saves. It is not pretty, he is not lights out, but effective. Ryan O"Rourke has pitched in 54 games in the majors. He has neither a save, hol, or a win. Low leverage pitching . I don't think he or Boshers would get claimed. If they did, there would likely be some else similar available.
