Who, ironically, himself was a low-level lottery ticket (17-year-old with a .742 OPS in Rookie/A- ball) in the 2016 trade for James Shields. (Tatis signed for $700K, so he was a decent prospect when signing, but not one of the top international prospects.) It appears Israel Puello signed for $460K in 2017. Not a top international prospect, but enough of an investment to show that he was well regarded.
