2018 Oakland Athletics Instructional League Roster
The A’s Instructional League team takes the field this weekend, ramping up toward game action next week. Their full roster is below.
The top-ranked prospect listed on the roster is outfielder Lazaro Armenteros. He was No. 8 on Oakland’s midseason list.
A’s fans may find the rehabbing list just as interesting as the actual roster. Rough injury luck hit both the major league team and the farm system this year. Kendall Graveman, A.J. Puk, James Kaprielian and Daulton Jefferies are all expected to continue their rehab work in Arizona.
