If Castro repeats his minor league stats (that's a huge if)...that probably leaves him right around a top 50 reliever in baseball (assuming he's staying under 70 innings in my scenario). That's pretty good, but also the best case scenario. Nearly a win out of a reliever may be the difference for this team, but I still doubt he outperforms the guys you mentioned earlier, and not a lot of guys can repeat their A Ball numbers in the Majors.
