Might be a little shady, but should work. 
 
my @array_of_strings;
my $string = '12-12 WANG 28 Jul H PRG SPEC 1320m Bk past midfield wide
+,btn car top T J Bau 57 (12) 7/7 Wnr: VENUS SERENA 1:26.82 13.5L';

@array_of_strings = split(/Wnr/, $string);

#replacing removed Wnr
$array_of_strings[1] = 'Wnr' . $array_of_strings[1];

#  $array_of_strings[0] = '12-12 WANG 28 Jul H PRG SPEC 1320m Bk past 
+midfield wide,btn car top T J Bau 57 (12) 7/7'
# $array_of_strings[1] = 'Wnr: VENUS SERENA 1:26.82 13.5L'
