According to BA, this is the highest rated minor leaguer White Sox returned at the deadline.
Out of the 89 minor leaguers traded at the deadline, William Bergolla is ranked 16th.
Alexander Albertus (Dodgers) is ranked 29th.
Jeral Perez (Dodgers) is ranked 33rd.
Jarold Rosario (Royals) is ranked 61st.
Trey McGough (Orioles) is ranked 85th.
I was expecting Jeral Perez to be leading this charge.
