Wong has joined the Red Sox in Tampa and will be activated ahead of Tuesday's game against the Rays, Chris Cotillo of The Springfield Republicane reports.
Wong will serve as Christian Vazquez's backup for the near future while Kevin Plawecki (hamstring) heads to the injured list. The 25-year-old Wong has yet to make his big-league debut and has struggled to a .148/.188/.246 line in 16 games for Triple-A Worcester this season.
