The ratings are not that high, but in many different franchises I have found Maicer Izturis to be very effective; some contact, some speed, some glove, and I've found him to be very clutch.

Also, if you hadn't mentioned defense specifically, I'd point you to Martin Prado. I know he's a starter now, and may make the all-star team and probably take over for Chipper, but I've always thought his best use might be a super utility role, but he'd be most useful as a guy you rotate through 4 or 5 positions a week, rather than as a defensive replacement.

You could also look at older guys who you could plausibly put in that role, depending on your budget; I'd go for a guy with speed who can play a few positions, like Chone Figgins.
