The first one I've seen is Baseball Prospectus (paywall): 1 Francisco Álvarez, C 2 Brett Baty, 3B/OF 3 Kevin Parada, C 4 Jett Williams, SS 5 Alex Ramirez, OF 6 Blake Tidwell, RHP 7 Ronny Mauricio, SS 8 Mark Vientos, 4C * 9 Dominic Hamel, RHP 10 Calvin Ziegler, RHP Parada and Williams were drafted this year. Matt Allen, who had been carried on past top 10 lists while recovering the TJ surgery has been dropped off - for now. Later * = They had "4C" after Vientos' name. I thought it was a typo and replaced it with 1B,3B. But the more I think about it, it means he can play the four corner positions, 1B,3B, LF and RF. I changed it back.
