Although it's the height of Rule 4 draft season, I typically reorder my top 25 pro prospects as we approach the end of May each year. This year there isn't as much chaos as there usually is near the top of the rankings, as just one top-10 prospect from this winter is currently in the majors.
We had two late but significant promotions that removed players from consideration for this list -- Jurickson Profar (Texas) and Kevin Gausman (Baltimore). Profar was the top prospect on my offseason list and would have remained so if he were still in the minors right now. Gausman would have moved up significantly from the offseason into the back of the top 10, as he was one of the top pitching prospects in the minors alongside Taijuan Walker and Archie Bradley.
Taveras hasn't had a huge start in Triple-A this year, hitting for average but not power with a poor walk rate, although he won't turn 21 until mid-June, and the raw hit and power tools are beyond any doubt. Whenever the Cardinals have an opening in their outfield, he's ready, as soon as he gets over a recent ankle injury that has had him on the shelf for a couple of weeks.
