Lamb (b. 1990) was a 2nd round pick by the Rangers in the 2011 June Amateur Draft out of Clemson. He played in the minors from 2011 to 2017 in the Rangers, White Sox and Rockies organizations, reaching AAA. He had a record of 27-23 with 429 strike outs and a 4.20 ERA.
I mailed to Lamb on March 27 and got the cards back on April 19, for a 23-day TAT.
