The Pirates are using Sunday to give several players a break from starting, as right fielder Gregory Polanco, second baseman Neil Walker and first baseman Pedro Alvarez are not in the lineup against the Cardinals.
The Cardinals are sending a lefty to the mound, making it the first time in 10 games that the Pirates have faced a lefty starter. Polanco and Alvarez have been in the lineup for that entire stretch but also sat in the team's last game against a southpaw. The switch-hitting Walker also received last Sunday off from starting.
With the shakeup to the lineup, Josh Harrison will man second and return to the leadoff spot, while Jung Ho Kang will bat second and play third base.
The Pirates are favorites (-115) at home Sunday.
