Montgomery was recalled from the alternate training site Friday ahead of his start against the Red Sox.
Montgomery was in line to make his season debut that got pushed back due to the Marlins' COVID-19 outbreak, but he'll officially join the 30-man roster Friday and start against Boston. The southpaw made two appearances (one start) for the Yankees in 2019, recording a 6.75 ERA and 1.75 WHIP over four innings.
