The Red Sox transferred Kiner-Falefa (forearm) from the 10-day injured list to the 60-day IL on Tuesday.
The transaction clears up a spot on the 40-man roster and ensures that Kiner-Falefa won't be available for the Red Sox until at least Aug. 18 while he continues to recover from a stress reaction in his left forearm. Kiner-Falefa was cleared to begin a hitting progression shortly after the All-Star break, but it's unclear where he currently stands in his rehab program or how close he might be to heading out on a rehab assignment.
