The Mets promoted Ewing from High-A Brooklyn to Double-A Binghamton on Sunday, Pat Ragazzo of SI.com reports.
Ewing earned the promotion after slashing .288/.387/.388 with two home runs and 44 stolen bases over 78 games with Brooklyn this season. The 21-year-old saw most of his action in center field with Brooklyn, but he also made starts in the corner outfield and at second base.
