Isiah Kiner-Falefa (forearm) went 1-for-3 with two walks in a minor league rehab game for Triple-A Worcester on Tuesday.
Kiner-Falefa is expected to stay in Triple-A Worcester until rosters expand next week to prevent the Red Sox from having to make a challenging decision in a roster crunch. The 31-year-old has been out with forearm inflammation since late June.
