Madrigal will start at third base and bat ninth in Sunday's game against the Giants.
He'll pick up a third consecutive start despite having gotten on base at a .286 clip through his first two contests since being promoted from Triple-A Iowa on Friday. The Cubs have an opening in the lineup at the moment while Seiya Suzuki (undisclosed) tends to a minor injury, but once Suzuki is healthy, Madrigal will have to battle Trey Mancini or Christopher Morel for one spot in Chicago's everyday lineup.
