Green (0-1) allowed six runs (four earned) on eight hits and a walk with five strikeouts over four innings in a loss Monday to Arizona.
Green was able to draw eight swinging strikes in 79 pitches in his major league debut, but he got touched up for a pair of home runs and three doubles as the Diamondbacks were able to capitalize when Green missed in the zone. Green has shown more than enough promise to earn a spot in the Yankees rotation at some point in the near future, as he owns a brilliant 1.22 ERA in seven starts for Triple-A Scranton, but he will likely be ousted from the rotation when CC Sabathia returns from the disabled list, expected this Friday.
