Martinez (b. 1994) was a 17th round pick by the A's in the 2016 June Amateur Draft out of Arizona State University. He played in the A's system from 2016 to 2019, missing 2020 due to COVID. He has a record of 15-20 with 210 strike outs and a 3.11 ERA.
I mailed to Martinez on January 6 and got the card back on January 15, for a 9-day TAT.
