Pratt is out of the lineup for Sunday's game against the Diamondbacks.
Pratt will sit Sunday after starting the previous four games, and he went 2-for-12 with three walks, a steal and a run during that span. The 21-year-old has struggled to a .200/.317/.220 slash line with one double, six steals, two RBI and five runs in his first 17 big-league games. Joey Ortiz is taking over at shortstop for the series finale in Arizona.
