We are going to close some ground

This very subtle malaphor was heard on a conference call.  The speaker was indicating that the backlog was starting to get smaller.  This is a mixture of “gaining ground”  and “closing the gap”, both meaning to make progress.  “Close in” might also be in the mix.  From a quick internet search, this malaphor appears to be a common one.  Thanks to Sandy Shultis for sending this one in!
