Szynski (b. 1997) was a 4th round pick by the A's in the 2016 June Amateur Draft out of high school. He played in Rookie ball in 2016 where he went 0-3 with 8 strike outs and an 8.10 ERA. Szynski remains in the A's system after missing the last several seasons due to injury. According to MILB.com, he is on the Midland Rockhounds roster.
I mailed to Szynski on January 4 and got the card back on January 15, for an 11-day TAT.
