Mike Olt heading back to Triple-A

The Rangers have promoted infielder Mike Olt to Triple-A Round Rock, according to Fox Sports Southwest.

Olt returned from the disabled list Friday due to an issue with his vision. He hit .333 (4 for 12) in his first three games back from the DL. He had a .139 batting average with one home run and six RBI in 20 games played at Triple-A earlier this season.
