Herrera is getting his first major league start Tuesday at second base in place of the injured Scooter Gennett.
Herrera nearly made the Reds' big-league club on Opening Day after a good spring and was off to a good start at Triple-A Louisville, hitting .311/.373/.607 in 68 plate appearances. He's not a highly rated prospect, however, as he was a minor-league free agent after spending his professional career in the Rockies' minor-league system without getting a call up.
