Vientos (wrist) is expected to be activated from the 10-day injured list Sunday, Anthony DiComo of MLB.com reports.
Vientos played in a rehab game with Triple-A Syracuse on Friday, and it's apparently the only one he will need. The rookie infielder has been out since mid-August with left wrist tendinitis. He had been seeing regular action at third base before the injury and should return to playing almost every day.
