Cubs' Justin Steele: Activated ahead of Monday's start

The Cubs activated Steele (hamstring) from the 15-day injured list ahead of his scheduled start Monday against the Padres at Wrigley Field.

Steele will rejoin the rotation Monday after being sidelined since straining his left hamstring Opening Day. The left-hander threw just 63 pitches in his lone rehab outing, so he'll likely have his workload curtailed Monday to some degree.
