Worth noting

• Right fielder Justin Ruggiano was scratched from Saturday's lineup due to a sore left ankle. Ryan Sweeney took his spot and batted fifth.

• Friday's winner Jake Arrieta trimmed his season ERA to 2.53, the lowest by a Cubs pitcher in his first 20 starts of a season since Greg Maddux's 2.33 in 1992.

• Javier Baez's six homers through his first 18 games are the most by a Cubs rookie since 1925, when Mandy Brooks hit six through his first 15 contests.
