Save/Cancel/Close button behavior question

The attached image shows a dialog with a save/cancel button bank and a "x" icon to close the dialog. The question I have is this. Should the cancel button even be on the modal if it does not clear/cancel any of the values? I have it in now as a redundant way to close the dialog. Should I just use the "Save" button and rely on the "x" to close, or is the use of the "Cancel" as a redundant close acceptable? My thought was that having a positive action "Save" without a corresponding negative action "Cancel" is a pattern breaker.

Thanks for the feedback.
