Chile have the chance to claim back-to-back Copa America titles against Argentina on Sunday after sealing their passage to the decider of the Centenario tournament with a 2-0 win over a 10-man Colombia late Sunday (early Monday morning).
The defending champions without suspended Arturo Vidal raced out into a 2-0 lead after 11 minutes in Chicago courtesy of early goals from Charles Aranguiz and Jose Fuenzalida.
Colombia winger Juan Cuadrado headed a cross down to Aranguiz, who had the simple task of slotting it past David Ospina, before Fuenzalida tapped home from close range after an Alexis Sanchez shot came off the post.
However, as a severe storm made its way to Soldier Field, the second half of the contest was delayed for over two hours due to the threat of lightning.
The skies finally cleared and action resumed at almost 22:30 local time (03:30 GMT), but wet patches all over the pitch made things difficult for the players.
Colombia worked hard to reduce the deficit but were dealt a huge blow when Carlos Sanchez received a second yellow card in the 57th minute.
Chile held on to the win to seal their spot in the final against Argentina – a rematch of the 2015 decider in which the former came out winners after a penalty shoot-out.
