In corresponding moves, they have placed righty Phil Maton on the 15-day injured list due to right knee tendinitis and designated left-hander Drew Pomeranz for assignment.

The Cubs have recently been giving the ball to Matthew Boyd, Shota Imanaga and Colin Rea. In addition to their rotation pursuits, the Cubs should be on the lookout for relief arms in the coming weeks.
