EDGE Analysis

Cahill has been on the shelf with a shoulder strain for the past month. If he's able to work through his upcoming bullpen session with no setbacks, he'll be able advance his rehab by throwing a simulated game this weekend either in Milwaukee or with a minor-league affiliate. Cahill could rejoin the rotation in the next week or two.
