2022 Fantasy Outlook
Arm injuries always seem to be the story with Jefferies. In 2021 it was biceps tendinitis early in the year and a flexor strain at the end of the year. The 6-foot righty has thrown 193.1 pro innings since getting drafted in 2016. He has nine strikeouts in 17 career MLB innings, so even if he is more durable than expected, there's not a high fantasy ceiling. When healthy, he has shown solid command and a starter's pitch mix. The A's will let him compete for a rotation spot in spring training, but there's little reason to invest in drafts. Read Past Outlooks
Done for season
Jefferies (thoracic outlet syndrome) won't return this season, Matt Kawahara of the San Francisco Chronicle reports.
ANALYSIS
He had thoracic outlet syndrome surgery Monday, which included the removal of his first rib. Jefferies' entire pro career has been altered by consistent arm injuries, and while he has made it back from Tommy John surgery, this next challenge could be even tougher.

Past Fantasy Outlooks
2021
2020
After posting strong numbers at Double-A in 2019, Jefferies spent last season at the Athletics' alternate training site and made his big-league debut in September as the 29th man for a doubleheader, although he got a rude welcome from the Rangers. The right-hander features a mid-90s fastball, a potentially plus changeup and good command, mixing in a curveball and cutter. Oakland's careful approach with his recovery from Tommy John surgery in 2017 would seem to leave the 25-year-old ready for his first full big-league campaign. The question is where he fits onto the staff. If A.J. Puk is healthy, there's no room for Jefferies in the rotation, but he could provide some length in the bullpen behind Puk and Jesus Luzardo. Conversely, the team could opt to keep him stretched out at Triple-A. That makes him a risky fantasy option in 2021 drafts, but if a starting role opens up, Jefferies does have upside.
