Thanks, I didn't realize it's based on days in the MLB.
So in order to be considered a prospect, a guy has to still be eligible to win Rookie of the Year in the majors.
In other words, Sogard and Eaton are no longer prospects, even though they are better bets than Arias this year to play in Boston.
I'd also say if any position player on the list makes it to Boston this season it will Braiden Ward at #40... unless Romero rakes and there are so many injuries to infielders in Boston and Woo he gets the call.
Ward has one big league skill that can help a team win right now, and a pennant contender might be willing to trade for him, rather than someone like Campbell, who currently has none.
