The Reds recalled Friedl from Triple-A Louisville on Sunday.
The 30-year-old was optioned to Triple-A in early June after posting a .179/.259/.256 slash line through 178 plate appearances, but he'll get another chance with the Reds after Blake Dunn (elbow) landed on the injured list. Friedl filled the strong side of a platoon in center field at the start of the season, though it's unclear if he'll slide back into that role after posting an .841 OPS in 18 games for Louisville. The Reds will include him in the starting lineup and batting eighth versus right-hander Mitch Keller during Sunday's series finale in Pittsburgh.
