Mike Olt returning to action in Frisco

ARLINGTON, Texas -- Texas Rangers prospect Mike Olt is on his way back to Double-A Frisco.

Olt, who slumped badly in April and left Triple-A Round Rock to deal with issues with his vision, is set to be activated for Friday's game. Olt, one of the Rangers' top prospect who made his debut last season for 16 games in the big leagues, has been at extended spring training in Surprise, Ariz.

Olt hasn't appeared in a game since April 25 for Triple-A Round Rock. He tweeted Thursday afternoon that he was coming back to Frisco.

Olt has posted a .135/.235/.236 line with 32 strikeouts in 72 at bats in Triple-A Round Rock this season.
