Back in 2016, the Oakland A’s selected Daulton Jefferies with the 37th overall pick in the MLB Draft. He was considered to be the type of pitcher that could fly through their system given his outstanding command and advanced feel for pitching. Armed with low 90s fastball and an exceptional change, the biggest question with Jefferies was whether or not he could develop a consistent third offering.
Then came 2017. Jefferies lasted all of seven innings before he underwent Tommy John surgery, costing him virtually all of 2018 as well. He did come back for two innings in the Arizona Rookie League, allowing one hit while striking out five, but there were concerns as to whether or not he would able to ascend the ranks as previously hoped.
