Just for info...
In this case, you don't need (I'm working with GNU awk here) the -F to specify the field separator, nor do you need to specify whitespace in the output, the comma will "expand" to a single space in the output.
e.g.
awk '{ print $1, $3 }' myfilename
Also, for info, you could use cut, but then you'd need to explicitly define the delimiter,
e.g.
cut -d' ' -f1,3 file
Just some thoughts...
