Cubs shortstop Javy Baez will get an MRI on his left thumb Saturday as he continues to remain out of the lineup after jamming it on a headfirst slide last Sunday.
"When he came in today [Friday] he tried to swing," manager Joe Maddon said. "It still didn't feel right. As opposed to continually waiting, we just want to find out what we're dealing with."
Baez will miss his fourth consecutive game Friday and will miss Saturday's contest against the Brewers as well.
The Cubs won't have a timetable for him until after they see the results of the MRI.
