Wong is starting at first base and batting fifth in Saturday's game against the Rangers, Chris Cotillo of MassLive.com reports.
It's the first start for Wong in the field anywhere other than catcher in his major-league career, per Cotillo. Wong's move to first base allows Boston to start new acquisition Danny Jansen behind home plate for Saturday's contest. Since the All-Star break, Wong has slashed .289/.360/.489 with three doubles, two home runs and five RBI across 49 plate appearances.
