McKinney will travel with the Pirates on their road trip to Texas and is expected to be called up from Triple-A Indianapolis prior to Monday's game against the Rangers, Noah Hiles of the Pittsburgh Post-Gazette reports.
Andrew McCutchen (knee) landed on the injured list Saturday, which will likely push Bryan De La Cruz to designated hitter in most scenarios. In turn, Pittsburgh will be shorthanded in the outfield, which could leave McKinney as the starting right fielder against right-handed pitching.
