Seems like he is starting to get back on the map on the national level. Keith Law brought him up in his most recent podcast, here's what he said:
Michael Ohlman, who has kind of emerged. He's really been on a tear offensively for the past month plus. Poor defensive catcher, I don't know that he lasts at the position. But there's some bat speed there. There's some quickness in his wrists, a little long from his load to contact, but nothing that would concern me terribly.
He also said his offensive might be good enough to get him to the big leagues. Not a top 100 guy yet.
