The Braves are designating shortstop Jorge Mateo for assignment, relays Chad Bishop of The Atlanta Journal-Constitution. That’ll open a roster spot for Ha-Seong Kim, who’ll be on the active roster tomorrow as a utility player. Mauricio Dubón is slated for a super utility role but should remain in the lineup somewhere on the diamond most days. The veteran infielder has mostly been in a utility role and hit .240/.285/.380 with four home runs across 137 plate appearances. Atlanta has subtracted some speed from its bench between the Mateo DFA and trading Eli White to the Red Sox.
