Yankees' Jasson Dominguez: Placed on IL at Triple-A

Triple-A Scranton/Wilkes-Barre placed Dominguez on its 7-day injured list Sunday with what Yankees manager Aaron Boone termed as a left side injury, Bryan Hoch of MLB.com reports.

The 21-year-old was formally activated from the Yankees' 60-day injured list earlier this week after a long recovery from Tommy John surgery and was subsequently optioned down to Triple-A. Over nine games at Triple-A thus far, Dominguez hasn't taken long to settle into a groove at the plate, as he was slashing .389/.405/.639 with five extra-base hits and two stolen bases prior to being deactivated. The extent of Dominguez's side injury isn't fully known yet, with Boone noting that the young outfielder is set to undergo further testing.
