Matt Shaw is optimistic about beginning a rehab assignment with Triple-A Iowa on Tuesday.

Shaw, on the IL since June 29 with a hand strain, has been hitting of a Trajekt machine. It doesn’t seem likely that he’ll have a particularly significant role after joining the Cubs. Pedro Ramírez has been a modest upgrade as an infield backup, and the Cubs acquired Tyrone Taylor at the deadline as an additional outfield option versus lefties.
