The Dodgers selected Robinson's contract from Triple-A Oklahoma City on Thursday.
The 31-year-old will join the big club for the first time this season to make up for the loss of Will Smith, who landed on the injured list Thursday with neck inflammation. Robinson owns a .763 OPS through 84 plate appearances at Triple-A this season but isn't likely to receive many at-bats with the Dodgers while working as a backup to Dalton Rushing.
