The Tigers are expected to call up Sweeney from Triple-A Toledo on Friday, Kiley McDaniel of ESPN.com reports.
Sweeney was acquired from the Dodgers on July 30 as part of the return for Jack Flaherty. Since reporting to Triple-A Toledo, the 24-year-old infielder has slashed .381/.447/.667 with two homers and nine RBI across 47 plate appearances while also swiping four bags in 11 games. He has played almost exclusively at shortstop throughout his minor-league career and could now take playing time away from Javier Baez, who has struggled at the plate for most of the season.
