Mike Olt has experienced improvement with his vision problem. Olt was placed on the disabled list with Triple-A Round Rock earlier this month due to a nagging eye issue, but symptoms have improved following eye drops and medication. He's scheduled to head to Surprise, Arizona to begin workouts and will eventually make his way back to Triple-A. There's no timetable for his return, though. Olt was hitting just .139 (10-for-72) with one home run and 32 strikeouts in 20 games prior to being placed on the disabled list.
