Gittens (ankle) was activated off the 10-day injured list Friday and optioned to Triple-A Scranton-Wilkes-Barre.
Gittens spent time in the big leagues in June and July but didn't make much of an impression in limited playing time, hitting .111/.250/.194 in 44 trips to the plate. Anthony Rizzo is still on the COVID-19 injured list, but the Yankees also have Luke Voit to play first base, so Gittens isn't needed at the moment.
