Pratt is out of the lineup for Monday's game against the Reds.
Milwaukee will hand the 21-year-old his first day off since he was promoted from Triple-A Nashville last Tuesday. Joey Ortiz will step in at shortstop in place of Pratt, who went 7-for-19 (.368 average) with a 2:4 BB:K, three stolen bases, two runs and two RBI over his first six big-league starts.
