9 Mike Olt, 1B

Rangers infield prospect Mike Olt , who is on the minor-league disabled list with an eye issue, began a hitting program with Triple-A hitting coach Scott Coolbaugh.

General manager Jon Daniels told ESPN Sunday that eye specialists have not been able to locate a problem with Olt's vision. Olt was hitting .139 with a home run and six RBI in 20 minor-league games.

"You always like to have answers," Daniels said. "You deal with what you have."

At the beginning of the season, Rangers infield prospect Mike Olt was a prime minor-league stash candidate. A top prospect who has shown the willingness to play all over the field to get his bat in the lineup, Olt seemed like a great bet to make an impact at the major-league level before long. Whether by trade or injury, it looked like we would see Olt again before long as he seemed intent on forcing his way into the lineup.

Unfortunately, Olt is batting just .139 with one home run at Triple-A Round Rock, and he has already struck out in 32 of his 72 at-bats. Olt's extended slump to begin the season has the Rangers so baffled that he has been placed on the disabled list until they can find the source of his issues. Right now, the team is targeting his eyesight as the source, but visits with specialists have yet to find anything.

Olt entered the season ranked 22nd in Baseball America's prospect rankings, But after a month-plus of the season, it is starting to look like Olt might not even be worth a roster spot for most Fantasy owners, especially in leagues that do not allow an extra spot for minor-league players.

There are guys down in the minors who stand a better chance of making a Fantasy impact this season at this point. 

The Rangers placed first baseman Mike Olt on the disabled list while playing with Triple-A Round Rock Tuesday, the Fort Worth Star-Telegram reports. Olt is dealing with an eye issue. 

Expected to see a specialist in 10-14 days, Olt could be cleared to return to action following his visit. The infielder has hit just .139 with one homer and 32 strikeouts over 20 games this season and Texas feels the eye issue could be a big reason for his struggles.
