I honestly feel sad for Matthews: he got his second podium in a monument this year, and during the race I was thinking loudly "Matthews still in the mix = a good chance for a podium". And then... the commissaires decided he went for a walk with his adversaries a bit too much... Imho, he first went to Bettiol / Teuns (nothing wrong with that), passed them on his right (nothing wrong) and kept going until he was almost at the barrier.
It all seems a bit too much, because Politt clearly wasn't coming over him.
