The Yankees announced today that they have selected the contract of lefty Justus Sheffield, the organization’s top pitching prospect. He’ll be heading up for his first taste of the majors.

To create space on the 40-man roster, outfielder Clint Frazier was moved to the 60-day DL. The Yanks also brought up righty Domingo German to bolster their pitching options down the stretch.

Sheffield’s promotion was already reported over the weekend, but had not yet formally been made. The organization first had to sort out its roster machinations. Frazier, who came to the club along with Sheffield in the 2016 Andrew Miller swap, is going to be sidelined the rest of the year owing to his ongoing concussion issues.

Now that Sheffield is officially on the roster, it’ll be interesting to see how he’s utilized. Perhaps he will have some opportunities down the stretch, while the Yanks seek to hold off the A’s for home-field advantage in the Wild Card game. And it’s still conceivable that Sheffield could earn a role on the postseason roster.
