Oh, I see, you are calling glob in scalar context where it returns the number of files matching. Also, you don't need mget when you have already used glob to resolve the name. get will do in that case:
($file) = $sftp->glob($file, names_only => 1); defined $file or die "file not found"; $sftp->get($file, "$ai_dest_day/$file");

    Ok now I am getting the file names and downloading them the way I was hoping for with one exception. In my script I want a file "IRP_20130410" the remote server has a file named "IRP_20130410000438.txt" The remote windows machine adds 6 characters for time and the ".txt" extension. I want to be able to match the file name I am looking for and don't care about the remaining characters. So can I just put a wild card in the glob?

    ($file) = $sftp->glob("${file}*", names_only => 1); defined $file or die "file not found"; $sftp->get($file, "$ai_dest_day/$file");
      yes, glob also accepts Perl regular expressions:
      ... my $start = quotemeta "$file$yesterday"; my ($file) = $sftp->glob(qr/^$start\d{6}$/, names_only => 1); ...
      But there are easier ways to do what you want. For instance, you can use a regular expression matching all the prefixes in @ai_files_day plus $yesterday plus any six digits and let mget download all the files matching:
      $sftp->setcwd($ai_dir); my $starts = join('|', map quotemeta, @ai_files_day); $sftp->mget(qr/^(?:$starts)$yesterday\d{6}$/, $ai_dest_day);
