Dave Wallace played several minor league seasons in the Indians organization as a catcher before beginning his coaching career as a staff assistant in Cleveland from 2009-10.

With Matt Wieters‘ future in Baltimore looking cloudy, Sisco could be the backstop of the future.

Each weekday during the minor-league season, FanGraphs is providing a status update on multiple rookie-eligible players. Note that Age denotes the relevant prospect’s baseball age (i.e. as of July 1st of the current year); Top-15, the prospect’s place on Marc Hulet’s preseason organizational list; and Top-100, that same prospect’s rank on Hulet’s overall top-100 list.

NOTE: In no way are the three players presented in this article meant to represent the three singular top performers of last month in the minor leagues. They are merely players who had clearly dominant Mays about whom I have especially relevant and novel information to add.

Summary
