Last November, in comparing Blake Swihart with Jarrod Saltalamacchia at a similar age, I wrote: "Swihart's performance in the first four months of 2017 should determine whether he has more, less or about the same trade value as Saltalamacchia had on July 31, 2010" when the Texas Rangers traded Saltalamacchia to the Red Sox for the humble package of Chris McGuiness, Roman Mendez, Michael Thomas and cash.

SoxProspects never ranked McGuiness, Mendez or Thomas among the franchise's Top 20 prospects.
I can't imagine that Swihart would command a greater return this month.
