It’s official.

And it’s ugly.

Aaron Judge joined the party of the Yankees’ walking wounded Sunday, going on the injured list with a “pretty significant” strain to his oblique, manager Aaron Boone said. Boone would not speculate on a timetable for Judge’s return, which does not bode well for the outfielder, who went down on a swing Saturday.

Infielder Thairo Estrada was recalled from Triple-A Scranton/Wilkes-Barre. It appears Tyler Wade will serve as the fourth outfielder for the time being.

The Yankees’ makeshift lineup looks abysmal, and their IL is stacked. Judge joins Giancarlo Stanton, Aaron Hicks and Jacoby Ellsbury as injured outfielders. Infielders out include Gary Sanchez, Greg Bird, Troy Tulowitzki, Didi Gregorius and Miguel Andujar. On the mound, Luis Severino, Dellin Betances and Jordan Montgomery are still unable to help.
