The 22-year-old Hurkacz broke third seed Thiem
four times, including in the final games of each set, to record
the biggest win of his career.
Austrian Thiem, who beat Roger Federer on Sunday to win his
first career Masters 1000 title at the BNP Paribas Open, was
uncharacteristically sloppy on the Grandstand court.
Kei Nishikori was also sent packing from the second round after
Serbian Dusan Lajovic stunned the Japanese world number six 2-6
The fifth seed had a first-round bye and appeared headed for a
routine victory until Lajovic, who was misfiring in the early
stages of the match, suddenly stepped up his game.
"He definitely raised his level (in the) second and third sets.
He wasn't missing much like in the first set. He served well in
the end," said Nishikori.
"Maybe I didn't play quite my best today. Credit to him today."
Nishikori, playing in his first match since falling in the third
round at Indian Wells last week, had his serve broken five times
during the match.
"I'm trying to keep my head up," said Nishikori. "Claycourt
season is coming. It's a completely new season. I'll try to have
good practice, two more weeks, and be ready for Monte Carlo."
Next up for world number 44 Lajovic, who had lost in the first
round of five tour-level events this season, will be a clash
with Nick Kyrgios after the Australian defeated qualifier
Alexander Bublik of Kazakhstan 7-5 6-3.
Djokovic needed just over an hour to brush aside Australian
Tomic 7-6(2) 6-2 and advance to the third round of a tournament
