for opening all files in a directory consider perldoc -f readdir 
my $zz = param('team');
my $z = param('squad');

if (param) {
  $sd = "../data/data_mlb";
  opendir( DIR, $sd) || die;
  while( ($filename = readdir(DIR))){
    next if "$sd\/$filename" =~ /\/\./;  ##skip . files
    push @dots, "$sd\/$filename";
  }  ## end of while
  @dots = sort @dots;
  closedir(DIR);
  for(my $a=0;$a<@dots;$a++){
    open (FILE, $dots[$a]);
    push @foo, <FILE>;
    if ($a+1 eq @dots) {
      close FILE;
      open (FILE, $dots[$a]);
      push @foo2, <FILE>;
      } ## end of if
    close FILE;
  }  ## end of for
