In acquiring Ben Zobrist and Yunel Escobar for John Jaso, Daniel Robertson, and Boog Powell, the deep trade line coming from Gio Gonzalez and in turn from Ben Grieve, Astros manager A.J. Hinch, and Angel Berroa rolls on:
Jason Wojciechowski would term this a seventh-generation Athletic, exceeding sixth-generation Athletic Eric Sogard. Jason Wojciechowski has declined to call Zobrist and Escobar seventh-generation Athletics because he defines generations as flowing through the centerpiece of a trade. I agree with him that Robertson is the centerpiece of this trade which would make Zobrist and Escobar only fifth-generation Athletics on the Woj-scale, but I think it's more enjoyable to give the player the longest-possible lineage. We therefore must accept there is a schism in how to calculate a trade/compensation generation. I propose the abbreviations wGen and kGen to avoid confusion, as in the phrase "Ben Zobrist is a 5th wGen/7th kGen player.
There remain only three players on the 40-man roster the A's acquired in the draft: Sonny Gray, Sean Doolittle, and A.J. Griffin.
Andy Parrino was designated for assignment to clear space on the 40-man roster for the two new players: A higher-resolution version may be downloaded at this link: (link).
Update (10:08 PM): Jason Wojciechowski reminded me that Daniel Robertson's lineage is more interesting than I realized Saturday morning, as Robertson was drafted using a compensatory draft pick for Josh Willingham's free agency. Besides tracing to Ben Grieve and A.J. Hinch through John Jaso, Zobrist and Escobar also trace back to Frank Thomas through Daniel Robertson! The maps have been updated to reflect this change.
