Madrigal was placed on the 10-day injured list with a right groin strain Saturday, Gordon Wittenmyer of NBC Sports Chicago reports.
Madrigal exited Friday's matchup with a groin issue, and he'll be sidelined for at least a week and a half after being diagnosed with a strain. Zach McKinstry is starting at second base Saturday against the Giants and should see the majority of the playing time at the keystone during Madrigal's absence.
