Rafaela is expected to move to second base Saturday, when shortstop Trevor Story (shoulder) will be activated off the 60-day injured list, MLB.com reports.
Second base has been a revolving door all season for the Red Sox, whose second basemen have combined for league lows in batting average (.196) and OPS (.535). The position had been designated for Vaughn Grissom, but his injuries, setbacks and performance in the minors prevented that plan from being executed. Rafaela, whose two-run home run was the winning blow Friday, has slumped of late, going 5-for-36 (.139) with 14 strikeouts over the last 11 contests.
