From Rosenthal:
Sources: Garcia trade stalled due to #Braves’ medical concern on #Twins’ prospect. Still could revive, but both teams working alternatives.
Here is story behind the story. I'm sure this is who the Braves targeted:
Double-A Chattanooga lefty Tyler Jay, taken sixth overall in the 2015 draft out of Illinois, is being evaluated for thoracic outlet syndrome and is likely headed for season-ending surgery.
Jay, 23, is rated the Twins’ No. 5 prospect by both Baseball America and MLB.com despite throwing a total of 16 innings the past two seasons. Signed to a bonus of $3.89 million, Jay made 13 starts with a 2.84 earned-run average at Class A Fort Myers in the first half of 2016, but shoulder weakness after a midseason promotion to Double-A landed him on the disabled list.
Tests last summer had ruled out a shoulder injury or TOS. Instead, the diagnosis last August was neuropraxia, which is considered a mild nerve injury, and the decision was made to move Jay to the bullpen full-time this spring.
This, from a Twins fans message board:
Reading up on TOS and seeing the past cases on it doesn't give me much hope. I think the only Pitcher that came back and was as successful post surgery as they were pre surgery was Chris Young.
