Curt Partch reminds me of Logan Ondrusek. They both have good velocity, struggle with command at times, had mediocre minor league numbers, and couldn't get lefties out to save their lives. When the Reds sent Ondrusek to the AFL, they hoped a team would be intrigued by him and offer something valuable in a trade, but no one took the bait. Next thing you know, Ondrusek learned a cutter, and the rest is history.
