If Jacque can get close to what he did last year, he's more than worth keeping on the roster and playing almost everyday especially for what he's being paid.
The only way one of the two doesn't go on the DL is if they're both out for a maximum of two days. Otherwise one of them will have to go on the DL. There's just no other option as the Cubs can't live with 2 players on the bench who just can't play.
