Humphreys is a prep kid out of Crystal River, Florida, that was signed in the 18th round of the 2015 draft. He only got in seven professional games that year and all were for the GCL Mets out of the pen (11.2-IP, 7-K, 1-BB, 1.54, 1.11).
In 2016, he returned to starting and impressed in Kingsport (12-starts, 69,1-IP, 76-K, 15-BB, 3.76, 1.15). He also led the Appy league in strikeouts.
Lots of flags here, but yes. If he was fully healed and was producing at least at the level he was producing at last year before his back went south, I would add at least one more year to his contract.
Players have no say in what positions they play. They can stop by the manager’s office and voice an opinion but managers (and their boss upstairs) have usually decided who plays where during the pre-season camp.
