Rangers general manager Chris Young told reporters on Tuesday that the “acute” injury happened during this season and wasn’t something that had existed prior to the 2022 draft.
Rocker had 42 strikeouts in 28 innings over six starts for Class A Hickory this season while going 2-2 with a 3.86 ERA. He had just seven walks.
The 6-foot-5, 245-pound Rocker was 28-10 with a 2.89 ERA over 42 games from 2019 to ’21 at Vanderbilt. He received a $5.2 million bonus after signing with the Rangers in 2022.
In other news, Corey Seager, who has been out with a hamstring injury, will be activated by the Rangers after he gets over a stomach illness. He had been eligible to come off the injured list on Monday.
