Steele was diagnosed with a left hamstring strain Thursday and will be placed on the injured list, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

Steele suffered the injury in Thursday's season opener against the Rangers as he attempted to field a bunt. Manager Craig Counsell didn't commit to a minimum 15-day stint for Steele, but a clearer timeline should emerge after he undergoes an MRI on Friday. With Jameson Taillon (back) also sidelined, the Cubs rotation is shorthanded. Drew Smyly is a candidate to shift from a relief to starting role as a result.
