Creating a one liner with wget, grep and mv

I have the following simplified script, that consists of a download (wget), a grab of only the lines with a comma (grep) and a rename of the file to indicate its date of origin (mv):
grep ',' datafile.csv
mv datafile.csv datafile.`date +"%Y%m%d%H%M%S"`.csv

However, what i really want to do is create a one liner, such that I am not dependent on file names, but simply treat the downloaded file as one object. Hence, I need something like this:
wget | grep ',' > datafile.`date +"%Y%m%d%H%M%S"`.csv

How do I create a one liner for this? Thanks in advance

wget --quiet -O - | grep ',' > datafile.`date +"%Y%m%d%H%M%S"`.csv
