CHICAGO: Chile stormed into the Copa America final here Wednesday, beating Colombia 2-0 in a weather-disrupted semi-final that took more than four hours to complete.

The defending champions advanced to a repeat of last year's final against Argentina on Sunday after a whirlwind start left Colombia chasing the game.

Chile, who had destroyed Mexico 7-0 in the quarter-finals on Saturday, picked up where they left off, scoring twice in the opening 11 minutes to take a grip on the contest.

Bayer Leverkusen midfielder Charles Aranguiz opened the scoring in the seventh minute before Jose Pedro Fuenzalida made it 2-0 after 11 minutes.

But the explosive start to the contest was overshadowed by the intervention of Mother Nature at half-time, as a powerful electrical thunderstorm rolled into downtown Chicago and halted play.

Tens of thousands of spectators were ordered to take shelter inside the stadium, leaving the ground empty as torrential rain pounded the stands.

For a while it looked as if play would be abandoned, with the teams forced to return to the venue on Thursday to complete the remaining 45 minutes.

However a break in the weather allowed teams of ground staff to set about clearing excess water from the field, and after a delay of two hours and 25 minutes, the second half resumed at 10:25pm local time (0325 GMT).

When play got under way both sides produced one of the most entertaining halfs of the tournament, Colombia attacking relentlessly in an effort to get back into the match and Chile chasing a third goal to kill the game off.

Penalty appeal

Colombia had appeals for a penalty waved away early in the second half when Daniel Torres tumbled over the outstretched leg of Gonzalo Jara in the penalty area.

With Real Madrid star James Rodriguez doing his best to take control of the match, Colombia looked lively in attack but were unable to find the final ball to unlock Chile's defense.

The Colombians' job became even more daunting in the 57th minute when Aston Villa midfielder Carlos Sanchez was sent off, collecting a second yellow for a clumsy challenge on Aranguiz.

Chile almost took an unassailable lead soon afterwards when only a superb diving save by Arsenal goalkeeper David Ospina thwarted Erick Pulgar's close-range header.

The closing stages of the game descended into a niggly encounter, with referee Chicas Aguilar of El Salvador eventually issuing eight yellow cards and one red.

Colombia continued to chase the game relentlessly, but came up short, paying the price for a lackadaisical start which saw Chile seize control with two goals in the first 11 minutes.

Fuenzalida was the architect of the opener, racing clear of the Colombian defense down the right flank before crossing to Alexis Sanchez.

The Arsenal star was beaten to the ball by Colombia's Juan Cuadrado, but the Juventus player could only succeed in heading back to the feet of Aranguiz who tapped in from close range.

Four minutes later, Chile doubled their lead.

A long goal kick from Chile goalkeeper Claudio Bravo found Sanchez, who turned Santiago Arias inside out on the edge of the penalty area before unleashing a fierce low shot which struck the bottom of the post.

The ball rolled into the path of Fuenzalida who had the simplest of finishes to make it 2-0 after only 11 minutes.

Sunday's final will be the second time Argentina and Chile have met in the tournament. Argentina beat the Chileans 2-1 in their opening Group D earlier this month. - AFP
