It's one of my favorite posts every year, and we'll do it for every team from the Astros on down to the GCL. So where did the 25 members of the 2017 Opening Day roster come from?
Pitchers
Chris Devenski: Sent to the Astros on August 3, 2012 as the PTBNL trade with the White Sox that sent Brett Myers to Chicago in exchange for Matt Heidenreich and Blair Walters.
Michael Feliz: Signed as an amateur free agent on May 19, 2010 after the A's voided his amateur free agent contract in March 2010.
