The world No 10 was beaten 7-6 (7-1) 6-1 in 89 minutes having struggled with his first serve throughout the match in the Power Horse Cup.
Pella, who missed a set point in the 11th game of the opener, made no mistake in the tie-break where he conceded just the fourth point.
In a one-sided second set, the world No 101 from Buenos Aires clinched a well-deserved victory by reeling off six straight games.
The defeated Serb could win just eight of the final 32 points, as Pella booked his quarter-final spot, where he will face seventh-seed Viktor Troicki, a 6-3 7-6 (7/3) victor over Grega Zemlja.
Tommy Haas will face the man who knocked him out of the Australian Open, Jarkko Nieminen, after he beat Ivan Dodig 3-6, 6-4, 7-5 in two hours.
"It was a tough battle," said Haas on the ATP World Tour's website. "I was close to losing, down 4-5, 15-30 in the third set. Ivan played a terrific match. It was tough conditions, with rain in between.
"It wasn't the best for my old bones. Jarkko is a very experienced player and it will be good to get revenge tomorrow."
Nieminen overcame Roberto Bautista Agut 6-4, 5-7, 6-3 in two hours and 33 minutes. while third seeded wild card Juan Monaco beat b 30-year-old Andre Ghem 6-4, 6-4 to reach his third quarter-final of the year.
Ghem won his first tour-level match in February 2006 at Costa do Sauipe (d. Kuerten). "It is always nice to play at a place where you have good memories," said Monaco.
"I played really well today. I knew from the beginning that the weather was not great. I now play Tobias Kamke, a good player who will have the support of the crowd."
