Rangers farm report: Kumar Rocker is throwing off a mound, possibly destined for Arizona Fall League

(Rangers Today/Jeff Wilson)
Kumar Rocker, as we said last month and again this week, is healthy.
The Rangers’ first-round pick this year at No. 3 overall is in Arizona building up for the starts of fall instructs next month and potentially for the Surprise Saguaros of the Arizona Fall League.
But before rushing to buy tickets, everything is contingent on Rocker … being healthy.
What was the issue with Carter’s leg?
