High-A Greensboro placed Blanco on its 7-day injured list Sunday due to an unspecified injury.
Blanco may be tending to a lower-body issue, as Anthony Murphy of Baseball America notes that the 21-year-old was lifted for a pinch hitter shortly after legging out a triple in Saturday's game. The first baseman is slashing .237/.319/.500 with 12 home runs and one stolen base over 210 plate appearances with Greensboro on the season.
