Italy eliminate Swiatek's Poland to reach second straight BJK Cup final
World number two Swiatek came from a set down to beat Jasmine Paolini in her singles rubber but the Italian earned immediate revenge over the five-time Grand Slam winner in the deciding doubles clash.
Paolini and veteran Sara Errani overcame Swiatek and Katarzyna Kawa 7-5, 7-5 in the doubles rubber to send the four-time champions through to Wednesday's final.
In the opening singles rubber, Italy's Lucia Bronzetti dispatched Magda Linette in straight sets 6-4, 7-6(3).
That was followed by Swiatek's three-set battle with Paolini which ran over two-and-a-half hours.
"It was tough today... the intensity was insane, I was a little bit tired but I said to myself, you still have to play the doubles, you have to give everything for Italy, for my team," said Paolini.
"When I lost the (singles) match I was a little bit sad, but then tried to go in the locker room and think positive about the doubles."
Linette, world number 38, was largely outclassed by Bronzetti, ranked 78th, in the first singles rubber.
At 4-1 down in the second set, Linette battled back strongly to force a tie-break but was eventually beaten when she slapped a return into the net after saving one match point.
It left the pressure on Swiatek to deliver, which she did in thrilling fashion.
Beaten every time in their three prior clashes and having never managed to take a set off Swiatek, Paolini battled with fierce determination from the outset.
Swiatek crushed the world number four in straight sets in the French Open final earlier this year but found a vastly tougher opponent in Malaga.
The Pole saved two break points to hold at 2-2 and then broke with a fizzing forehand to take the lead.
It did not deter Paolini, who doubled down and won the next four games, securing two breaks of her own, to claim the first set.
Swiatek spurned three break points in the final game and showed signs of tiredness after helping Poland reach the semi-finals by winning both her singles match and a doubles rubber against the Czech Republic.
Paolini had done the same for last year's runners-up Italy against Japan but dug deep to keep Swiatek at bay until the 10th and final game of the second set, which the Pole won to force a third.
After the players exchanged breaks in the decider, Swiatek eventually triumphed when Paolini went long.
Swiatek won 13 of the 16 break points she faced, proving the stronger in the key moments.
"For sure it was tough, my energy level was down in the second set but I managed to get back and that was the most important thing," said Swiatek, explaining she had "no time to celebrate" as the job was not done yet.
