Baez was scratched from the lineup for Saturday's game against the Cardinals with a bruised right heel, Mark Gonzales of the Chicago Tribune reports.
Baez's heel issues date back nearly two weeks to when he was forced to exit a game May 19 after making a defensive play. He missed the next two games but had since been in the lineup for nine straight contests prior to Saturday's scratch. Addison Russell will replace him at shortstop.
