ZAGREB, Croatia — Juan Martin Del Potro rallied from two sets down and overcame a finger injury to beat Marin Cilic 6-7 (4), 2-6, 7-5, 6-4, 6-3 as Argentina drew level at 2-2 with Croatia in the Davis Cup final on Sunday.
The best-of-five series will now be decided in the second reverse singles played later Sunday between Croatia’s Ivo Karlovic and Argentina’s Federico Delbonis.
Croatia was leading 2-1 in the series after winning the doubles on Saturday.
Only twice since the World Group Davis Cup format was introduced in 1981 has a team come back from 2-1 down in the final.
Argentina is targeting its first Davis Cup title after playing in four finals. Croatia won in 2005.
"I was calm, I hoped all the time that I could win and I did it," said Del Potro, displaying a bandage on his little finger on his non-racket left hand.
He said the injury happened in the fifth set while he was trying to catch a ball.
"I’m very happy to hand my team a chance of a victory," Del Potro said
The action-packed match at Arena Zagreb that lasted nearly five hours saw plenty of drama created by two players with similar styles.
"It is very difficult to lose such an important match," Cilic said. "I feel a lot of disappointment."
Cilic had a furious start to race to a 3-0 lead including a break in Del Potro’s first service game. The Croat capitalized on the first of three break points with a cracking forehand winner.
Del Potro fought back in the 7th game with Cilic under pressure at deuce. Two ground strokes, first a forehand long then a looping backhand, saw Del Potro break at the sixth attempt.
In the tiebreaker, Cilic raced to a 5-0 lead to seal the game with a slice backhand down the line that Del Potro could not control.
Under pressure after losing his fourth straight tiebreaker during the finals, Del Potro started the second set slowly and dropped his serve in the fifth game with a double fault and another in the seventh at love.
At that point, Cilic seemed to be cruising toward victory with some spectacular ground strokes that the tired-looking Argentine watched in disbelief.
But then Del Potro, who has recovered after two injury-hit years, showed the form he displayed in beating now top-ranked Andy Murray as Argentina knocked out holder Britain in the semifinals.
He broke Cilic in the 12th and 10th games in the third and fourth sets respectively to send the match into the decider.
"After losing the third set, I was still confident I could win as he looked tired," Cilic said. "I started pushing a bit too hard, handing him a chance for a comeback."
Trailing 15-40 in the eighth game of the final set, Cilic sent a forehand beyond the baseline to give Del Potro the decisive break. He served out the match, sending the Argentine fans and their bench into jubilant celebrations.
