The Reds recalled Lopez from Triple-A Louisville on Wednesday. He'll start at shortstop and bat eighth in Wednesday's series finale in Miami.
Barrero began the season in Louisville and has slashed just .209/.262/.377 with nine homers, 27 runs, 24 RBI and five stolen bases over 55 games with the Triple-A club. In spite of his lackluster performance in the minors, the 24-year-old will join the active roster as infield depth after Brandon Drury was traded to the Padres on Tuesday.
