Brantly was returned to Triple-A Scranton/Wilkes-Barre on Monday.
Brantly's contract was selected after Kyle Higashioka tested positive for COVID-19 following the All-Star break. The 32-year-old Brantly went 2-for-15 with a double and three strikeouts across four games, but he'll head back to the minors after the Yankees acquired right-hander Clay Holmes from Pittsburgh on Monday.
