The Cubs have designated infielder Mike Olt for assignment, the club announced. His roster spot was needed for the acquisition of Austin Jackson, which Chicago also made official.

Olt, 27, has never regained his trajectory after topping out as a prospect that rated as high as 22nd on league-wide rankings. In the midst of a disappointing 2013 season, he was dealt to Chicago as part of a package deal that sent righty Matt Garza to the Rangers. Vision issues were noted as a cause for concern at the time, and Olt has dealt with a right wrist fracture more recently.

Last season represented Olt’s first real opportunity at the big league level, in spite of that rough 2013, but he did not make the most of it. Over 258 plate appearances, Olt swatted 12 home runs but slashed just .160/.248/.356 while striking out an even 100 times.

He cracked the Opening Day roster as Chicago’s starting third baseman, but that run was short-lived. Olt suffered the aforementioned wrist injury and was ultimately replaced, as had been expected anyway, by Kris Bryant — after the team was assured of keeping another year of future control.

Nevertheless, another team will likely be glad to take a shot on Olt’s upside. He’s always been regarded as a potentially solid defender at third base and has shown plenty of pop in his right-handed bat. And despite his struggles in relatively scant action at the big league level, Olt has hit will at Triple-A over the last two years. In 246 turns at bat there this season, he’s slashed .273/.346/.477.
