A new multi-station line forms on Billy Beane's Athletics Roster Tree (BBART), going from the trade of Addison Russell, Billy McKinney, and Dan Straily for Jeff Samardzija to the subsequent trade of Samardzija and Michael Ynoa for Marcus Semien, Chris Bassitt, Josh Phegley, and Rangel Ravelo. Jorge De Leon, a waiver claim from earlier this offseason, falls off the BBART station map.
